问题 Why was the hydraulic fuel pump seal important for the space shuttle?
The great significanee of Voss’s findings lies in______.I. strengthening his determination to join in space flights.Ⅱ. furthering his understanding of NASA.Ⅲ. consolidating his astronaut status in NASA programs

选项 A、I only
B、Ⅱ only
C、I, II and Ⅲ all included
D、I and Ⅱ only

答案D

解析 从文章中的第二段最后两句"At the end of the summer,he,like the other NASA-ASEE fellows working at Marshall summarized his findings in a formal presentation and detailed paper. It was a valuable moment for Voss because the ASEE program gave him added understanding of NASA,deepened his desire to fly in space,and intensified his application for astronaut status".可以看出,对于Voss来说是一段宝贵时间,因为参与ASEE而加深了他对NASA的了解,增强了他参与太空飞行的欲望,使他更想申请做一名宇航员。
