Most people on Earth accept it fairly easily that US astronauts (宇航员) got to the moon on July 20, 1969. But there are those who do not believe it. The moon rocks were not evidence enough. Neither were the words of the astronauts themselves or the photographs. So the US National Aeronautics and Space Administration (NASA) (美国航空航天局) has asked an expert to write a book to prove that yes, indeed, Americans did land on the Moon. Actually, NASA has been going round and round in the argument for decades, but doubters still could be seen everywhere on the Internet.
Those who doubt the Apollo moon landings maintain that the US lacked the technology to send humans to the Moon and was so eager to win the Soviets in the space race that it faked (捏造) the moon mission on movie sets. The doubters say the faking was done so poorly that there is enough evidence of cheat, including a picture of astronauts planting the American flag that shows the flag rippling (微微抖动) in the wind. T
A. a picture of astronauts planting the American flag
B. the rocks brought back from the moon
C. the American flag on the moon
D. the wind on the moon
