问题 Why was the hydraulic fuel pump seal important for the space shuttle?
How many flights will Voss have finished if his four-month mission starts in July 2000?

选项 A、Three.
B、Two.
C、Four.
D、Five.

答案C

解析 推断题。题干意为“如果Voss成功完成始自2000年 7月为期四个月的飞行,他一共进行了几次飞行?”由第三段可知,自1978年以来Voss已经三次参与太空项目,目前他正在接受训练,准备作为宇航员从2000年7月起被送往国际站并在那里逗留四个月。文中提到的那个50岁的,住在休斯顿的老军官指的就是Voss,所以这应是第四次。
