riding a bicycle without a helmet smoking cigarettes wearing a hat while in the Sun eating with dirty hands
I gave my students this multiple choice question: Which activity is an example of a good health habit?

Only one answer is correct among these 4 choices:
- riding a bicycle without a helmet
- smoking cigarettes
- wearing a hat while in the Sun
- eating with dirty hands

Could you tell me which one is correct?
