If added to the end of this passage, which of the following conclusions would fit best?
A. The owl is a nocturnal animal. This means it is active at night. The owl's excellent sense
of sight and sound enable it to find food in the dark.
B. Mice are nocturnal animals. This means they are active at night. Similar to the owl, mice
use their excellent sense of smell to find food in the dark.
C. Both mice and owls are nocturnal. This means they are active at night. Because these
animals are active at night, they must sleep during the day. This makes them especially
vulnerable to attack from diurnal animals.
D. Some animals are nocturnal. This means they are active at night. The owl and the mouse
are good examples of nocturnal animals that use their senses to find food in the dark.
