Scientists blindfold bats. Change it into a ba sentence

Answer: The scientist blindfolded the bat and let it fly in the house.

In the study of bats, scientists once covered their eyes with black cloth, but they found that bats can fly normally without any influence. This is because bats emit ultrasonic waves during flight and fly according to the principle of echolocation, which shows that sound can transmit information.
