Question

alison and her dad are going on a hike. how can they best protect themselves from sun exposure?
by wearing short - sleeved shirts and shorts
by applying sunscreen with a minimal spf
by hiking in the middle of the day
by wearing protective clothing

Explanation:

Wearing short - sleeved shirts and shorts exposes more skin to the sun. Applying sunscreen with a minimal SPF (Sun Protection Factor) does not offer sufficient protection. Hiking in the middle of the day (when the sun is strongest) increases sun exposure risk. Wearing protective clothing covers more skin and reduces direct sun exposure.

Answer:

by wearing protective clothing
