Question

Passage

A seal is a marine mammal that has specific physical features that allow it to thrive
when it is not on land. Its whiskers act as a form of radar, detecting movement in the
water so the seal can more easily locate its prey. In addition, a silvery lining in the eyes
makes it possible for more light to be absorbed; this helps the seal find food even in the
darker depths of the water.
