Matching exercise to identify computer parts based on descriptions.

Let’s go step by step to match each description with the correct picture.

We’ll read each numbered sentence and think about what computer part it describes. Then we’ll find the matching image below.

---

1. “It is a device used for moving the pointer around the screen.”
→ That’s a mouse. Look for the picture of a mouse (with a cord or wireless). It’s in the top row, far right.

2. “It is a square device used to store information, but with a small capacity.”
→ This sounds like a floppy disk. It’s old-school, square, and holds little data. Picture is in second row, second from left.

3. “It is a device used to publish your essays or home works.”
→ You print things out → printer. Picture is in second row, far right.

4. “To use internet, you need to switch it on and connect it to your pc.”
→ That’s a router (for Wi-Fi/internet). Picture is in third row, fourth from left — blue box with antenna.

5. “It is a round device in which you can record a film, music or images.”
→ A CD/DVD (round disc). Picture is bottom row, first on left — colorful discs.

6. “With this device you can type words, numbers, or letters.”
→ That’s a keyboard. Picture is third row, first on left.

7. “It is the central processing unit. It is like the brain of the computer.”
→ The CPU tower (the big box that runs everything). Picture is second row, third from left.

8. “It is an output device. It is used to play audio on your computer.”
→ Speakers. Picture is top row, fourth from left — two black speakers.

9. “It is an output device. It allows you to play your favorite games.”
→ Hmm… could be monitor? But wait — game controllers are input. Actually, playing games usually means seeing them → monitor/screen. But let’s check: maybe they mean console? No — look at pictures. There’s a joystick (game controller) in second row, first on left. But that’s INPUT. Wait — perhaps they mean the screen? Let’s hold off.

Wait — re-read: “play your favorite games” — if it’s OUTPUT, then it must be something that shows or plays the game → monitor. But there’s also headphones? No, that’s sound. Let’s see picture #15 is headphones — that’s for listening. Maybe #9 is monitor? But #11 says “reflect images or texts” — that’s definitely monitor. So maybe #9 is... actually, let’s skip and come back.

Actually — looking again: “output device” + “play games” — perhaps they mean speakers? But #8 is already speakers. Or maybe headphones? But #15 is headphones. Wait — perhaps #9 is the joystick? But joystick is INPUT. Confusing.

Hold on — let’s look at all descriptions again carefully.

Maybe #9 is referring to the monitor? But #11 says “reflect images or texts for user’s view” — that’s clearly monitor. So #9 might be misworded? Or perhaps it’s the game controller? But that’s not output.

Wait — another idea: maybe “play your favorite games” refers to the computer itself? But no, that’s too vague.

Let’s look at the pictures again. There’s a picture of a joystick/gamepad — that’s for playing games, but it’s input. Unless the question meant “device used TO play games” meaning the tool you use — which would be input. But it says “output device”.

This is tricky. Let’s move on and come back.

10. “This device works as a power saver. It provides battery when electricity runs out.”
→ That’s a UPS (uninterruptible power supply) or backup battery. But in the pictures, do we have that? Looking — there’s a picture of a power strip/surge protector? Not exactly. Wait — there’s a picture of a battery icon? No. Actually, in the images, I don’t see a clear UPS. Wait — perhaps they mean laptop battery? But laptop is #12.

Wait — look at picture #10’s spot — it’s empty? No, we’re matching descriptions to pictures. The pictures are fixed; we assign numbers to them.

Actually, let’s list all pictures and label them mentally:

Top row of pictures (left to right):
- CD/DVD (colorful discs)
- Laptop
- Remote controls? Or maybe modem/router? Wait — no, third is remote? Actually, looking: third picture in top row is two remotes? That doesn’t fit. Wait — let's number the picture positions.

There are 20 picture slots arranged in 4 rows of 5.

Let me map them:

Row 1 (pictures):
1. Colorful discs (CDs)
2. Laptop
3. Two remote controls? Or maybe external drives? Actually, looks like two gray boxes — possibly hard drives or modems.
4. Two speakers
5. Mouse

Row 2:
6. Joystick/game controller
7. Floppy disk
8. CPU tower
9. Monitor
10. Printer

Row 3:
11. Keyboard
12. Headphones
13. USB drive + folder (storage)
14. Router (blue with antenna)
15. Desktop computer (tower + monitor + keyboard)

Row 4:
16. Web browsers (Firefox, Chrome icons)
17. Shortcut arrow icon
18. Penguin (Linux mascot?) or maybe virus?
19. Smiley face with CD — maybe software/installer?
20. Bug on monitor — virus/malware

Now let’s rematch descriptions to these.

1. Moving pointer → mouse → picture 5

2. Square, small storage → floppy disk → picture 7

3. Publish essays → printer → picture 10

4. Switch on for internet → router → picture 14

5. Round, record film/music → CD/DVD → picture 1

6. Type words → keyboard → picture 11

7. Central processing unit → CPU tower → picture 8

8. Output, play audio → speakers → picture 4

9. Output, play games → ? If output, and play games, likely monitor → picture 9

But #11 says “reflect images or texts” — that’s also monitor. Conflict?

Wait — #11: “This device allows to reflect the images or texts for the user’s view.” → Definitely monitor → picture 9

Then what is #9? “Allows you to play your favorite games” — if it’s output, and not monitor, then perhaps speakers? But #8 is speakers. Or headphones? #12 is headphones.

Perhaps #9 is the game controller? But it’s input. Unless the question has a mistake.

Another thought: maybe “play your favorite games” refers to the computer system that runs games — but that’s not a single device.

Look at picture 15: desktop computer — includes CPU, monitor, etc. Description #16 says: “It is a big computer which includes a CPU, monitor, keyboard, all of them by separated.” → That matches picture 15.

So #16 → picture 15

Then #9: perhaps it’s the headphones? Because you can play games with sound through headphones. And headphones are output. Picture 12 is headphones.

Description #15: “It is an output device used to listen to your favorite music placed in your ears.” → That’s headphones → picture 12

So #15 → picture 12

Then #9: “allows you to play your favorite games” — if not monitor, not speakers, not headphones, then what? Perhaps they mean the joystick even though it’s input? But it says “output device”.

Wait — let’s read #9 again: “It is an output device. It allows you to play your favorite games.”

In gaming, the main output devices are monitor (visual) and speakers/headphones (audio). Since monitor is taken by #11, and speakers by #8, headphones by #15, then perhaps #9 is redundant or misassigned.

But there’s another possibility: maybe “play your favorite games” refers to the game console or something, but we don’t have that.

Looking back at pictures — picture 6 is joystick. Maybe the question meant “device used to play games” without specifying input/output, but it does say “output”.

Perhaps it’s a trick, and #9 is the monitor, and #11 is something else? But #11 is clearly monitor.

Let’s check #11: “reflect the images or texts for the user’s view” — yes, monitor.

#9: “play your favorite games” — perhaps they mean the sound system for games, so speakers or headphones. But both are taken.

Another idea: maybe “play your favorite games” refers to the software or browser, but those aren’t hardware output devices.

Let’s look at description #17: “It is a video device which allows to communicate with relatives, friends or other people.” → That’s webcam or video call app. Picture 16 is web browsers — close, but not quite. Picture 19 is smiley with CD — maybe software. Picture 20 is bug — virus.

Perhaps #17 is webcam, but we don’t have a webcam picture. Picture 15 is full desktop, which might include webcam, but not specified.

This is getting messy. Let’s try to match the obvious ones first.

List of clear matches:

- 1 → mouse → pic 5
- 2 → floppy disk → pic 7
- 3 → printer → pic 10
- 4 → router → pic 14
- 5 → CD/DVD → pic 1
- 6 → keyboard → pic 11
- 7 → CPU → pic 8
- 8 → speakers → pic 4
- 10 → power saver/battery → ? What picture? Picture 3 is two gray boxes — could be external batteries or UPS? Or perhaps it’s the laptop battery, but laptop is separate. Description #10: “provides battery when electricity runs out” — that’s UPS. In pictures, is there a UPS? Picture 3 might be it — two units, one could be UPS. Let’s assume pic 3 for #10.
- 11 → monitor → pic 9
- 12 → personal computer you can take anywhere → laptop → pic 2
- 13 → devices to store/transmit info via USB → USB drive → pic 13 (USB stick next to folder)
- 14 → dangerous software to destroy/steal → virus/malware → pic 20 (bug on monitor) or pic 18 (penguin? Linux is not virus). Pic 20 is clearly virus.
- 15 → output device to listen to music in ears → headphones → pic 12
- 16 → big computer with CPU, monitor, keyboard separated → desktop setup → pic 15
- 17 → video device to communicate → webcam or video call. Pictures: pic 16 is browsers, pic 19 is smiley with CD — perhaps video chat software. But hardware? We don’t have webcam. Perhaps they mean the monitor or something. Another thought: pic 17 is shortcut arrow — not relevant. Pic 18 is penguin — Linux, not for communication. Perhaps #17 is the browser for video calls → pic 16
- 18 → device to make copies of music, pictures, etc. → copy machine? Or USB drive? But USB is #13. Or CD burner? Pic 1 is CDs, but that’s media. Description: “make copies” — could be CD writer, but not shown. Pic 13 is USB, which can copy files. But #13 is already USB for storage/transmit. Perhaps #18 is the same? No. Another idea: “make copies” could mean duplicating files, so any storage, but specifically, perhaps the folder icon represents file copying. Pic 13 has USB and folder. But #13 is assigned to USB. Let’s see description #18: “make copies of your favorite music, pictures, data or movies” — this sounds like a CD/DVD burner or just general storage. But we have pic 1 as CDs. Perhaps #18 is pic 1? But #5 is already CDs for recording.

This is confusing. Let’s list all descriptions and possible matches systematically.

Make a table:

Desc # | Description | Likely Device | Picture # (from earlier mapping)
---|---|---|---
1 | move pointer | mouse | 5
2 | square, small storage | floppy disk | 7
3 | publish essays | printer | 10
4 | switch on for internet | router | 14
5 | round, record film/music | CD/DVD | 1
6 | type words | keyboard | 11
7 | CPU, brain | CPU tower | 8
8 | output, play audio | speakers | 4
9 | output, play games | ? | let's say monitor, but conflict with 11. Or headphones, but 15 is headphones. Perhaps it's the game controller, even though input. But it says output. Maybe it's a mistake, and it's input. In many contexts, "play games" implies controller. Let's tentatively assign to pic 6 (joystick), even though it's input, because it's the only game-related device.
10 | power saver, battery when no electricity | UPS or backup battery | pic 3 (two gray boxes, could be UPS)
11 | reflect images/texts for view | monitor | 9
12 | personal computer, take anywhere | laptop | 2
13 | store/transmit info via USB | USB drive | 13
14 | dangerous software, destroy/steal | virus | 20
15 | output, listen to music in ears | headphones | 12
16 | big computer with CPU, monitor, keyboard separated | desktop computer | 15
17 | video device to communicate | webcam or video call app | pic 16 (browsers for video calls) or pic 19 (smiley with CD, maybe Skype?) . Let's say pic 16 for browsers used for communication.
18 | make copies of music, pictures, etc. | this could be CD burner or just storage. Pic 1 is CDs, but #5 is for recording. Perhaps it's the folder icon for file copying. Pic 13 has folder, but #13 is USB. Another picture: pic 19 is smiley with CD — might represent software for burning CDs. Or pic 18 is penguin — not relevant. Perhaps #18 is pic 1, but duplicate. Let's think: "make copies" might mean duplicating files, so any storage medium, but specifically, perhaps the external hard drive or something. In pictures, pic 3 is two gray boxes — could be external drives. But we assigned #10 to pic 3. Conflict.

Perhaps #10 is not pic 3. What is pic 3? Two remote controls? That doesn't make sense for computer parts. Upon closer inspection, in the original image, picture 3 in top row is two devices that look like external hard drives or modems. For #10 "power saver", it might not be that. Is there a battery icon? No. Perhaps "power saver" refers to the laptop's battery, but laptop is #12.

Another idea: "provides battery when electricity runs out" — that's definitely UPS. In some worksheets, they show a UPS as a box. Pic 3 might be it. Let's keep it.

For #18: "make copies" — perhaps it's the CD/DVD for burning copies. So pic 1. But #5 is also CD for recording. #5 says "record a film, music or images" — which is burning to CD. #18 says "make copies of your favorite music, pictures, data or movies" — also burning to CD. So perhaps both refer to CD, but that can't be.

Unless #5 is the CD itself, and #18 is the CD drive or burner. But we don't have a CD drive picture. Pic 1 is the discs, not the drive.

Perhaps #18 is the USB drive, but #13 is already USB.

Let's look at description #19: "It is a direct access to a specific app, or document in order to save time looking for them." → That's a shortcut icon. Picture 17 is a shortcut arrow — perfect match.

#20: "They are search engines that allow people to surf the net." → Search engines are websites, represented by browser icons. Picture 16 is Firefox and Chrome — browsers, which are used to access search engines. Close enough.

So #19 → pic 17
#20 → pic 16

Now back to #17: "video device to communicate" — with #16 and #19 taken, what's left? Pic 18 is penguin (Linux), pic 19 is smiley with CD, pic 20 is virus. None seem to fit. Perhaps pic 19 is for video chat — smiley face suggests communication. So #17 → pic 19

Then #18: "make copies" — what's left? Pic 18 is penguin — not relevant. Pic 3 is still unassigned? We have pic 3 for #10, but let's list assigned pictures.

Assigned so far:

1 → 5 (mouse)
2 → 7 (floppy)
3 → 10 (printer)
4 → 14 (router)
5 → 1 (CD)
6 → 11 (keyboard)
7 → 8 (CPU)
8 → 4 (speakers)
9 → ?
10 → 3 (UPS?)
11 → 9 (monitor)
12 → 2 (laptop)
13 → 13 (USB)
14 → 20 (virus)
15 → 12 (headphones)
16 → 15 (desktop)
17 → 19 (smiley with CD for communication)
18 → ?
19 → 17 (shortcut)
20 → 16 (browsers)

Left pictures: pic 6 (joystick), pic 18 (penguin)

Left descriptions: #9 and #18

#9: output device to play games — if we assign joystick to it, even though it's input, because it's the only game-related device. Many students might associate joystick with playing games.

#18: make copies of music, etc. — penguin doesn't fit. Perhaps "make copies" refers to the Linux OS or something, but that's stretch.

Another possibility: "make copies" could mean using a computer to duplicate files, so the computer itself, but desktop is #16.

Perhaps #18 is the folder icon, but it's part of pic 13, which is assigned to #13.

Pic 13 is USB drive and folder together. Description #13 is "devices which is used to store, and transmit information placed in a USB port" — that's the USB drive. The folder might represent the data, but it's one picture.

For #18, "make copies" — perhaps it's the CD, but #5 is already CD.

Let's read #18 again: "It is a device used to make copies of your favorite music, pictures, data or movies."

In computing, "make copies" often means duplicating files, which can be done with any storage, but specifically, it might refer to a CD/DVD burner or external hard drive.

In the pictures, pic 3 is two gray boxes — could be external hard drives. If we assign #10 to something else.

What is #10: "works as a power saver. It provides battery when electricity runs out." — that's UPS. Is there a UPS picture? In some worksheets, they show a UPS as a box with outlets. Pic 3 might be it, or perhaps not.

Another idea: "power saver" could refer to the laptop's power management, but laptop is #12.

Perhaps "provides battery" means the battery itself, but no picture of battery.

Let's consider that pic 3 might be external hard drives, and for #18 "make copies", external hard drives are used to backup/copy data.

Then for #10, what could it be? Perhaps the router has a battery? Unlikely.

Or perhaps "power saver" is misinterpreted. Another thought: in computers, "power saver" mode is a setting, not a device. But the description says "this device works as a power saver", so it must be a physical device.

Perhaps it's the surge protector or power strip. In pictures, is there a power strip? Not clearly.

Let's look at the original image description. In the user's image, picture 3 in top row is two devices that look like external hard drives or network attached storage.

For #10, if we can't find a UPS, perhaps it's not included, but we have to match all.

Another approach: let's count how many pictures are there and ensure all are matched.

Pictures: 20 positions.

Descriptions: 20.

From above, we have most matched except #9 and #18, and pictures 6 and 18 left.

Picture 6: joystick/game controller
Picture 18: penguin (Tux, Linux mascot)

Description #9: "output device to play games" — if we ignore "output" for a moment, joystick is used to play games, so assign #9 to pic 6.

Description #18: "make copies of music, pictures, etc." — Linux is an OS that can be used to manage files, but it's a stretch. Perhaps "make copies" refers to open-source software or something, but unlikely.

Perhaps "make copies" means using a computer to burn CDs, and the penguin represents Linux, which has burning software, but that's weak.

Another idea: in some contexts, "make copies" could mean photocopying, but that's not computer part.

Let's read #18 carefully: "It is a device used to make copies of your favorite music, pictures, data or movies."

This sounds like a CD/DVD writer or external hard drive for backing up.

In the pictures, pic 1 is CDs, which are the media, not the device to make copies. The device would be the drive, which is not shown separately.

Perhaps pic 3 is the external hard drive, and we assign #18 to pic 3.

Then for #10, what is left? Only pic 18 (penguin).

Description #10: "power saver, provides battery" — penguin doesn't fit.

Unless "power saver" is a misnomer, and it's something else.

Perhaps "provides battery" means the device has its own battery, like a laptop, but laptop is #12.

I think there might be a mistake in my initial assignment.

Let's try a different strategy. Let's list the pictures and what they are, then match descriptions.

Picture 1: CDs/DVDs — for storing data, recording media
Picture 2: Laptop — portable computer
Picture 3: Two gray boxes — likely external hard drives or UPS
Picture 4: Speakers — output audio
Picture 5: Mouse — input, move pointer
Picture 6: Joystick — input, for games
Picture 7: Floppy disk — old storage
Picture 8: CPU tower — main computer unit
Picture 9: Monitor — display
Picture 10: Printer — output, print documents
Picture 11: Keyboard — input, type
Picture 12: Headphones — output, listen to audio
Picture 13: USB drive and folder — storage, transfer data
Picture 14: Router — for internet
Picture 15: Desktop computer (tower, monitor, keyboard) — full system
Picture 16: Web browsers (Firefox, Chrome) — for surfing net
Picture 17: Shortcut icon — quick access to apps
Picture 18: Penguin (Linux) — operating system
Picture 19: Smiley face with CD — perhaps software installer or video chat
Picture 20: Bug on monitor — virus/malware

Now match descriptions:

1. move pointer -> mouse -> pic 5
2. square, small storage -> floppy -> pic 7
3. publish essays -> printer -> pic 10
4. switch on for internet -> router -> pic 14
5. round, record film/music -> CD -> pic 1
6. type words -> keyboard -> pic 11
7. CPU, brain -> CPU tower -> pic 8
8. output, play audio -> speakers -> pic 4
9. output, play games -> ? If output, and play games, it must be monitor or speakers or headphones. Monitor is for visual, speakers/headphones for audio. Since #11 is monitor, #8 is speakers, #15 is headphones, perhaps #9 is monitor, and #11 is something else? But #11 is clearly "reflect images or texts" — monitor.

Perhaps #9 is the headphones, and #15 is something else, but #15 is "listen to music in ears" — headphones.

Unless #9 is the game controller, and we overlook "output".

In many educational materials, they might not be strict about input/output for this level.

So let's assign #9 to pic 6 (joystick) for playing games.

10. power saver, provides battery -> UPS -> pic 3 (assume the gray boxes are UPS)
11. reflect images/texts -> monitor -> pic 9
12. personal computer, take anywhere -> laptop -> pic 2
13. store/transmit via USB -> USB drive -> pic 13
14. dangerous software -> virus -> pic 20
15. listen to music in ears -> headphones -> pic 12
16. big computer with components separated -> desktop -> pic 15
17. video device to communicate -> video call -> pic 19 (smiley with CD, perhaps representing Skype or Zoom)
18. make copies of music, etc. -> this could be the external hard drive for backup, so pic 3, but pic 3 is assigned to #10. Conflict.

If pic 3 is external hard drives, then for #18 "make copies", it fits, as you can copy data to external drive.

For #10 "power saver, provides battery", what could it be? Perhaps the laptop has a battery, but laptop is #12.

Or perhaps "power saver" refers to the router having a battery backup, but unlikely.

Another possibility: "provides battery when electricity runs out" — that's UPS, and in some images, UPS is shown as a box. Pic 3 might be it, and for #18, "make copies" could be the CD, but #5 is already CD.

Perhaps #18 is the folder icon, but it's part of pic 13.

Let's notice that pic 13 has both USB drive and folder. Description #13 is "devices which is used to store, and transmit information placed in a USB port" — that's the USB drive. The folder might represent the data, but it's one picture.

For #18, "make copies" — perhaps it's the act of copying files, represented by the folder, but it's not a device.

I think the intended match for #18 is the external hard drive, and for #10, it might be something else.

Let's look at description #10: "This device works as a power saver. It provides battery when electricity runs out."

In computers, a common device for this is UPS, but if not available, perhaps they mean the laptop's battery, but laptop is separate.

Perhaps "power saver" is a mis translation, and it's "power supply" or something.

Another idea: in some contexts, "power saver" could refer to the power management unit, but not a device.

Perhaps it's the battery itself, but no picture.

Let's consider that pic 3 is two external hard drives, and for #18 "make copies", it fits.

For #10, what is left? Pic 18 (penguin).

Description #10: "provides battery" — penguin doesn't provide battery.

Unless "battery" is metaphorical, but unlikely.

Perhaps "when electricity runs out" means when the computer is off, but still.

I recall that in some worksheets, they have a picture of a battery for this, but here it's not.

Let's check the last few.

Description #19: "direct access to a specific app or document" -> shortcut -> pic 17
Description #20: "search engines to surf the net" -> browsers -> pic 16

So pic 16 and 17 are taken.

Left pictures: pic 6 (joystick), pic 18 (penguin)

Left descriptions: #9 and #18

For #9: "output device to play games" — if we must choose, and since joystick is for games, assign #9 to pic 6, ignoring "output" for now.

For #18: "make copies of music, pictures, etc." — the penguin represents Linux, which is an OS that can be used to manage and copy files, so perhaps #18 to pic 18.

It's a bit forced, but possible.

Perhaps "make copies" refers to open-source software allowing duplication, but weak.

Another thought: in Linux, there are tools for burning CDs, so "make copies" of music to CD, and the penguin represents the OS that enables it.

So let's go with that.

So final matches:

1 -> 5
2 -> 7
3 -> 10
4 -> 14
5 -> 1
6 -> 11
7 -> 8
8 -> 4
9 -> 6 (joystick for playing games)
10 -> 3 (UPS or external drive, but we'll say UPS)
11 -> 9
12 -> 2
13 -> 13
14 -> 20
15 -> 12
16 -> 15
17 -> 19
18 -> 18 (penguin for making copies via OS)
19 -> 17
20 -> 16

But for #10, if pic 3 is external hard drives, then "provides battery" doesn't fit.

Perhaps pic 3 is UPS, and for #18, "make copies" is not matched well.

Let's swap #10 and #18.

Suppose #10 is for external hard drive? But "provides battery" doesn't fit.

Unless "power saver" means it saves power by being efficient, but not standard.

I think the best bet is to assign #10 to pic 3 as UPS, and #18 to pic 18 as Linux for file management.

Perhaps "make copies" refers to the CD, and #5 is for recording, #18 for copying, but same device.

I recall that in the description #5: "record a film, music or images" — that's creating content on CD.
#18: "make copies of your favorite music, pictures, data or movies" — that's duplicating existing content, which can also be done on CD or USB.

But since USB is #13, perhaps #18 is CD.

But pic 1 is already #5.

Unless the picture is used for both, but we can't.

Perhaps for #18, it's the folder icon, but it's part of pic 13.

I think I need to accept that #9 is joystick, #18 is penguin, and move on.

So the matching is:

1. mouse - 5
2. floppy - 7
3. printer - 10
4. router - 14
5. CD - 1
6. keyboard - 11
7. CPU - 8
8. speakers - 4
9. joystick - 6
10. UPS - 3
11. monitor - 9
12. laptop - 2
13. USB - 13
14. virus - 20
15. headphones - 12
16. desktop - 15
17. video chat - 19
18. Linux for copying - 18
19. shortcut - 17
20. browsers - 16

Now for the answer, we need to provide the picture number for each description.

So the final answer is the pairing.

Since the task is to match, and the user will fill in, we can list the picture number for each description number.

So:

Description 1 matches picture 5
Description 2 matches picture 7
Description 3 matches picture 10
Description 4 matches picture 14
Description 5 matches picture 1
Description 6 matches picture 11
Description 7 matches picture 8
Description 8 matches picture 4
Description 9 matches picture 6
Description 10 matches picture 3
Description 11 matches picture 9
Description 12 matches picture 2
Description 13 matches picture 13
Description 14 matches picture 20
Description 15 matches picture 12
Description 16 matches picture 15
Description 17 matches picture 19
Description 18 matches picture 18
Description 19 matches picture 17
Description 20 matches picture 16
