question 8
instructions
read the question carefully and select the best answer.
which sentence most strongly suggests the central idea in the previous passage?
a. \on october 14, 1947, pilot chuck yeager flew over the mojave desert in an naca - developed experimental research plane called the bell x - 1.\
b. \and he pierced the sound barrier for the first time in history.\
c. \the plane caused a loud noise — a sonic boom, just like the shockwave from the bullet and the bullwhip — but the pilot and the plane were safe.\
d. \the female computers on the ground verified the data transmitted from the instruments attached to the x - 1 on its record - breaking flight.\

Explanation:

The central idea of a passage about breaking the sound barrier is best captured by the sentence that states the historic milestone of first piercing the sound barrier. Option B directly identifies this core event, while the others provide supporting details (the date/flight details, the sonic boom effect, data verification) rather than the main central idea.

Answer:

B. "And he pierced the sound barrier for the first time in history!"
