Question

question 2
why should you wear bright or reflective clothing when biking?
so drivers can see you more easily
so your outfit matches your bike
so your friends can find you easily
so you can blend into your surroundings

Explanation:

Bright or reflective clothing increases visibility. When biking, being visible to drivers is crucial for safety. Matching the bike (no functional safety - related reason), friends finding (not the main safety - related purpose), and blending in (opposite of what is needed for safety) are not the main reasons.

Answer:

So drivers can see you more easily
