Use the following information to answer questions 37.
Some bats capture and eat moths while they are flying.
Insect-eating bats hunt using a sophisticated hearing system
like a submarine’s sonar to locate their prey. This is called
echolocation. The bats emit a high frequency shriek that
bounces off objects and they detect the echo that is returned.
This system is so sophisticated that bats can determine the
size of their prey and its direction.

reference book says that this powder helps the moth avoid being detected by the bats. You
infer this to mean that the powder would …

B. make the moth fly slower by increasing air resistance
C. give the moth a bad taste
D. camouflage the moth on trees
