Question

FIRST CORRECT ANSWER GETS BRAINLIEST
This question has two parts. First, answer Part A. Then, answer Part B.
Part A
How does Passage 3 support the claim that the U.S. military would like to
improve its sonar technology?

It illustrates how existing technology was developed through specific
examples.

It gives statistical evidence that explains how technology has
improved in the past.

It explains how bats echolocate and gives examples of situations
where echolocation might occur.

It describes how scientists train bats and observe specific behaviors
to learn how echolocation works.

Part B
Select two sentences from Passage 3 that provide relevant support for
the answer in Part A.

"'Bats make sounds, listen to echoes, and then see objects,' notes
Simmons." (paragraph 9)

"'We now know that bats have a method of doing synthetic aperture
sonar while flying that not only determines the distance and direction
of all the objects in a scene, but also reconstructs one specific
object's shape.'" (paragraph 9)

"In Simmons' experiments, the bats are trained to differentiate
sounds with the time separation of those sounds shortened to test
the bats' response." (paragraph 10)

"Today's electronic sonar processing can differentiate between echoes
about 12 millionths of a second apart." (paragraph 11)

"Bats have it down to 2 to 3 millionths of a second." (paragraph 11)

Answer 1

Answer:

part A D It describes how scientists train bats and observe specific behaviors to learn how echolocation works.

Part B B “‘We now know that bats have a method of doing synthetic aperture

sonar while flying that not only determines the distance and direction

of all the objects in a scene, but also reconstructs one specific

object’s shape.’” (paragraph 9)

C In Simmons’ experiments, the bats are trained to differentiate

sounds with the time separation of those sounds shortened to test

the bats’ response.” (paragraph 10)
