Step 1: Understand the parts and their functions

We are given five labeled parts of the eye:
1. Iris
2. Pupil
3. Eyebrow
4. Eyelid (upper eyelid is shown)
5. Eyelashes

And we have five function descriptions:

- "protect the eyes from dust or sand."
- "protects the eyes from sweat or rain."
- "moves downward to prevent some elements from entering the eye: for example, dust."
- "controls the amount of light that enters the pupil. It is the coloured part of the eye."
- "is a black circle in the middle of the iris. It lets light enter the eye."

Step 2: Match each part with the correct function

#### 1. The Iris
- The description: *"controls the amount of light that enters the pupil. It is the coloured part of the eye."*
- This matches exactly with the iris.
✔ Answer: controls the amount of light that enters the pupil. It is the coloured part of the eye.

#### 2. The Pupil
- The description: *"is a black circle in the middle of the iris. It lets light enter the eye."*
- This directly describes the pupil.
✔ Answer: is a black circle in the middle of the iris. It lets light enter the eye.

#### 3. The Eyebrow
- The description: *"protects the eyes from sweat or rain."*
- Eyebrows help divert sweat and rain away from the eyes.
✔ Answer: protects the eyes from sweat or rain.

#### 4. The Eyelid
- The description: *"moves downward to prevent some elements from entering the eye: for example, dust."*
- The eyelid (especially the upper one) closes to protect the eye.
✔ Answer: moves downward to prevent some elements from entering the eye: for example, dust.

#### 5. The Eyelashes
- The description: *"protect the eyes from dust or sand."*
- Eyelashes trap dust and particles before they reach the eye.
✔ Answer: protect the eyes from dust or sand.

✔ Final Answers:

1. The iris – *controls the amount of light that enters the pupil. It is the coloured part of the eye.*

2. The pupil – *is a black circle in the middle of the iris. It lets light enter the eye.*

3. The eyebrow – *protects the eyes from sweat or rain.*

4. The eyelid – *moves downward to prevent some elements from entering the eye: for example, dust.*

5. The eyelashes – *protect the eyes from dust or sand.*

This completes the matching task! Each part of the eye has been correctly paired with its function.
