Educational worksheet for learning prefixes and adjective suffixes with visual examples.

Let’s go through the worksheet step by step.

---

Exercise A: Prefixes

We are to fill in blanks with correct prefixes:
dis-, mis-, re-, un-, under-

1. I just can’t believe it! The story is ______believable.
→ “Unbelievable” means not believable → un-

2. No, that answer is ______correct. It is wrong.
→ “Incorrect” means not correct → in-? Wait — but “in-” isn’t on the list.
Wait — look again: options are dis-, mis-, re-, un-, under-
“Uncorrect” isn’t a word. But “incorrect” is — but “in-” not allowed.
Ah — maybe they mean “mis-correct”? No, that’s not right either.
Wait — perhaps it’s “dis-correct”? Also not standard.
Actually — let’s think: “incorrect” is the word — but since “in-” isn’t an option, maybe this is a trick?
Wait — no — look at sentence 2: “No, that answer is ______correct. It is wrong.”
The word should be “incorrect” — but since “in-” isn’t listed, perhaps they want “mis-”?
But “miscorrect” isn’t a word.
Wait — maybe it’s “un-correct”? Still not standard.
Hold on — perhaps it’s “dis-correct”? No.
Actually — I think there might be a mistake here — but let’s check common usage.
In many worksheets, “incorrect” is used — but since “in-” isn’t an option, maybe they expect “mis-” as in “mistaken”?
But the blank is before “correct”.
Wait — perhaps it’s “un-correct” — even though it’s not standard English, sometimes in beginner worksheets they accept it?
No — let’s look at the other sentences.

Actually — wait — sentence 2 says: “No, that answer is ______correct. It is wrong.”
The opposite of “correct” is “incorrect” — but since “in-” isn’t an option, maybe they meant “mis-” as in “mistakenly correct”? That doesn’t make sense.
Wait — perhaps it’s “dis-correct”? No.
I think there might be an error — but let’s look at the answer key logic.

Actually — upon second thought — in some contexts, “un-correct” is used informally — but it’s not standard.
Wait — let’s skip and come back.

3. Let’s look at this information again. We should ______view it before the test.
→ “Re-view” means to view again → re-

4. I saw Allison just a moment ago, but now I can’t find her! It seems that she ______appeared!
→ “Disappear” means to vanish → dis-

5. Oh, I’m sorry, I didn’t hear you correctly. I ______understood you.
→ “Misunderstood” means understood wrongly → mis-

6. The subway does not go over the land like a normal train. It moves ______ground.
→ “Underground” → under-

Now back to #2: “No, that answer is ______correct. It is wrong.”
The only prefix that makes sense with “correct” from the list is “in-” — but it’s not there.
Wait — perhaps it’s “mis-correct”? No.
Actually — I think it might be a typo — but in many worksheets, they use “incorrect” — but since “in-” isn’t an option, maybe they want “un-”?
But “uncorrect” is not a word.
Wait — let’s think differently — perhaps it’s “dis-correct”? No.
Actually — I recall that in some educational materials, they use “un-” for negation even if not standard — but that’s bad practice.
Wait — look at the first sentence: “unbelievable” — which is correct.
For #2, the only logical choice is “in-” — but it’s not listed.
Perhaps the worksheet has a mistake — but let’s assume they mean “incorrect” and since “in-” isn’t there, maybe it’s “mis-” as in “mistakenly correct”? That doesn’t fit.
Wait — another idea: perhaps it’s “un-correct” — and they accept it for beginners.
But I think the intended answer is “in-” — but since it’s not an option, maybe it’s “dis-”?
No — let’s check online or standard usage.
Actually — upon reflection, I think there might be an error in the worksheet — but for the sake of completing it, let’s see what fits.

Wait — perhaps it’s “mis-correct” — meaning incorrectly correct? That doesn’t make sense.
Another thought: maybe it’s “re-correct” — meaning to correct again? But the sentence says “it is wrong”, so not re-correct.
I think the best fit is “in-” — but since it’s not an option, perhaps the worksheet meant to include “in-” — but it didn’t.
Wait — look at the prefixes given: dis-, mis-, re-, un-, under-
“Un-” can be used for negation — like “unhappy”, “untrue” — so “uncorrect” might be accepted in this context, even though it’s not standard English.
In many school worksheets, they do use “un-” for “not” even with words that normally take “in-” or “im-”.
So for #2, likely they want “un-” → “uncorrect”

But let’s confirm with logic:
Sentence 2: “No, that answer is ______correct. It is wrong.”
If we put “un-”, it becomes “uncorrect” — which means not correct — which fits.
Even though “incorrect” is the standard word, in this context, with the given prefixes, “un-” is the only one that makes sense.
So I’ll go with “un-” for #2.

So Exercise A answers:
1. un
2. un (even though not standard, it's the only option that fits)
3. re
4. dis
5. mis
6. under

Wait — but for #2, if we use “un-”, it’s “uncorrect” — which is not a real word — but perhaps for the worksheet, it’s acceptable.
Alternatively, maybe it’s “mis-” — “miscorrect” — which also isn't a word.
I think the intended answer is “in-” — but since it’s not there, and “un-” is the closest, I'll go with “un-”.

Actually — let’s double-check sentence 2: “No, that answer is ______correct. It is wrong.”
The word should be “incorrect” — but since “in-” isn’t an option, and “un-” is used for negation in other words like “unbelievable”, perhaps they want “un-” here too.
Yes, I think that’s it.

So:
1. un
2. un
3. re
4. dis
5. mis
6. under

But wait — for #5: “I ______understood you.” → “misunderstood” — yes, “mis-”

For #6: “moves ______ground” → “underground” — “under-”

OK.

Now Exercise B: Adjective suffixes

Suffixes: -able, -ful, -less

1. The first woman is very tired. She wants to rest!
The second woman can’t stay still. She always wants to move! She is rest______.
→ “restless” means unable to rest → less

2. The first dog isn’t cute. He’s a little scary!
The second dog is very cute! He’s a ______dog.
→ “Cute” is already given — but we need a suffix.
“Cute” + suffix? “Cuteful”? Not a word.
“Cute” + “-able”? “Cuteable”? No.
“Cute” + “-less”? “Cuteless”? No.
Wait — the sentence says: “He’s a ______dog.”
And the suffixes are -able, -ful, -less
“Cute” is the adjective — but we need to add a suffix to make a new word?
Actually — look at the picture: the second dog is cute — so perhaps “lovable” or “adorable” — but those aren’t from the suffixes given.
Wait — the instruction says: “Complete the words that describe the pictures below. Use the suffixes from the list.”
List: -able, -ful, -less
For the second dog: “He’s a ______dog.”
Perhaps “lovable” — but “love” isn’t given.
Wait — maybe it’s “cute” + “-ful” → “cuteful”? Not a word.
Another idea: perhaps it’s “adorable” — but again, not from the list.
Wait — look at the first part: “The first dog isn’t cute. He’s a little scary!” — so the first dog is “scary” — which might be “frightful” or something — but not helpful.
For the second dog: “He’s a ______dog.”
Perhaps “playful”? But “play” isn’t given.
Wait — maybe it’s “cute” and we need to add a suffix to make a different word — but “cute” doesn’t combine with these suffixes.
Unless — perhaps it’s “lovable” — and “love” is implied? But the suffixes are to be added to base words.
Let’s read the instruction again: “Complete the words that describe the pictures below. Use the suffixes from the list.”
And the list is -able, -ful, -less
For the second dog, the word might be “adorable” — but “adore” isn’t given.
Perhaps it’s “cute” and we use “-ful” to make “cuteful” — but that’s not standard.
Another thought: maybe it’s “lovable” — and the base is “love” — but the picture shows a cute dog, so “lovable” makes sense.
But the suffix is “-able”, so “lovable” = love + able.
Similarly, for the first dog, “scary” might be “frightful” — but “fright” isn’t given.
Wait — let’s look at the third item.

3. Jason writes lots of lists, so he always remembers what he has to do. He never forgets!
But Melanie can’t remember anything! She’s very forget______.
→ “Forgetful” — so ful

Back to #2: for the second dog, “He’s a ______dog.”
Perhaps it’s “lovable” — and we use “-able” suffix.
Or “adorable” — same thing.
But the base word isn’t specified.
Maybe it’s “cute” and we add “-ful” — but “cuteful” isn’t a word.
Another idea: perhaps it’s “playful” — but again, not from the picture description.
Let’s think about the first dog: “He’s a little scary!” — so perhaps “frightful” — but “fright” isn’t given.
Wait — the instruction is to use the suffixes from the list to complete the words — so for each blank, we add one of the suffixes to a base word that is implied or given.

In #1, “rest” + “-less” = “restless”

In #3, “forget” + “-ful” = “forgetful”

In #2, for the second dog, “He’s a ______dog.” — the base word might be “love” or “adore” — but not given.
Perhaps it’s “cute” and we use “-able” to make “cuteable” — but that’s not standard.
Wait — maybe it’s “lovable” — and the base is “love” — which is common.
In many worksheets, they expect “lovable” for a cute dog.
So I’ll go with “lovable” — using “-able” suffix.

But the blank is “a ______dog” — so “lovable dog” — yes.

Alternatively, “adorable” — same suffix.

So for #2: able

But let’s confirm the suffixes: -able, -ful, -less

For #1: rest + less = restless

For #2: love + able = lovable (or adore + able = adorable)

For #3: forget + ful = forgetful

Yes.

So Exercise B answers:
1. less
2. able (assuming "lovable" or "adorable")
3. ful

Now, to summarize:

Exercise A:
1. un
2. un (though not standard, it's the only option)
3. re
4. dis
5. mis
6. under

Exercise B:
1. less
2. able
3. ful

But for Exercise A #2, I'm still unsure. Let me think again.

Sentence 2: "No, that answer is ______correct. It is wrong."

The word should be "incorrect" — but "in-" is not in the list. The list is dis-, mis-, re-, un-, under-

"Un-" can be used for negation, as in "unhappy", "untrue", so "uncorrect" might be accepted in this context for educational purposes.

Perhaps it's "mis-" — "miscorrect" — which isn't a word.

I think the intended answer is "in-" — but since it's not there, and "un-" is the closest, I'll go with "un-".

Some sources might use "un-" for "not" even with words that normally take "in-".

So I'll stick with that.

Final answers:

Exercise A:
1. un
2. un
3. re
4. dis
5. mis
6. under

Exercise B:
1. less
2. able
3. ful

Now, for the final answer, since the user didn't specify which exercise, I'll provide both.

But the response should have only the final answer after reasoning.

So in the Final Answer section, I'll list them.

But let's make sure about Exercise A #2.

Upon second thought, I recall that in some worksheets, they have "incorrect" with "in-", but here it's not an option. Perhaps it's a trick, and they want "dis-" for "dis-correct" — but that's not a word.

Another idea: perhaps it's "re-correct" — but the sentence says "it is wrong", so not re-correct.

I think "un-" is the best choice given the options.

So I'll proceed.
