The following paragraph contains an error. Read the entire passage. Then select the option that corrects the error.
Most people know that bats can find their way in the dark using echolocation. Bats make a series of high-pitched squeaks. Based on the way these sound waves diffract off objects around it, a bat can form a mental picture of its surroundings. Fewer people realize that humans can also learn to echolocate. A man named Daniel Kish can ride his bike even though he lost his vision at the age of one! Mr. Kish makes a sharp clicking sound with his tongue. By listening to the echoes of the click, he can easily navigate his surroundings.
Group of answer choices
a. Mr. Kish’s use of echolocation would be limited, due to the absorption of sound waves.
b. Mr. Kish actually navigates through the use of radar waves, not echolocation.
c. In echolocation, bats listen to the way sound waves refract, not diffract.
d. In echolocation, bats listen to the way sound waves reflect, not diffract.
