Question

a person’s risk of sunburn on a certain body part is greater the more directly the sun’s rays hit that body part. if a person is walking outside with no direct overhead (or anything), what body part has the greatest risk for sunburn? (assume none of the body parts mentioned below are covered by hats, etc.) options: forehead, nose, chin, top of the ears

Explanation:

When walking outside with the head overhead (exposed), the "top of the ears" is more directly exposed to the Sun's rays compared to the forehead (which might have some shadow from the brow or hairline), the nose (smaller area and sometimes partially shaded by the face structure), and the chin (usually in a more shaded position relative to the top of the ears). The top of the ears is more likely to have direct sun exposure as it is on the upper part of the head and less likely to be shaded by other facial features or structures when the head is upright and exposed.

Answer:

top of the ears
