Clear my choice
While observing primates at the zoo, you notice that the particular monkey you are watching uses its hands, feet, and tail to grasp branches while moving throughout the trees in its enclosure. This is most likely a(n)
A. New World monkey, because many of these species have a tail with grasping abilities similar to those observed in nonhuman primates hands and feet
B. Old World monkey, because many of these species have a tail with grasping abilities similar to those observed in nonhuman primate hands and feet
C. New World monkey, because these are the only monkeys that live in trees
D. Lesser ape, because many of these species have a tail with grasping abilities similar to those observed in nonhuman primate hands and feet

A. It gave us fight or flight instincts and helped us avoid danger.
B. It helped us to be independent and live alone.
C. Stress is never useful and it only harmed our early ancestors.
