1 The question raised in the first paragraph is one __________.
A that was asked by structural engineers a month ago
B that is too difficult for structural engineers to answer even now
C that was never difficult for before the terrorist attack
D that terrorists are eager to find a solution to
2 The project funded by the National Science Foundation __________.
A was first proposed by some engineers at UB
B took about two days to complete
C was to investigate the damage caused by the terrorist attack
D was to find out why some buildings could survive the blasts
3 The column mentioned by Dr. Whittaker _________.
A was part of the building close to the World Trade Center

C was shot through the window and the floor of the World Trade Center
D damaged many buildings in the vicinity of the World Trade Center
4 A surprising discovery made by the investigators during their visit to ground zero is that __________.

B some floor framing systems demonstrate resistance to explosion
C simple floor framing systems are more blast resistant
D floors in one of the adjacent buildings were pierced by tons of debris
5 What Dr. Reinhorn said in the last paragraph may imply all the following EXCEPT that __________.
A blast engineers should develop new solutions for terror-resistant design
B blast engineering can borrow technologies developed for terror-resistant design
C solutions developed for earthquake-resistant design may apply to terrorist-resistant design
D slast engineering emerges as a new branch of science
答案：1 C建筑设计是否能使建筑具有抵御恐怖袭击的性能，是一个月前世界贸易中心受到袭击之前人们从未想过的一个问题。这是第一段的主要内容。所以，只有C是正确答案。
2 D A不是正确选项，因为文章没有提及谁首先提出这个项目。B或C都不是文章所述的内容。答案可以在第三段中找到。
3 B有关本题的句子是第四段的第三句，“This building is many meters away from the World Trade Center and yet we see a column there that used to be Part of that building."这里的this buildin9指的是the building many meters away from the World Trade Center，而that buildin9指的是World Trade Center。
4 B选项A不是答案，因为文章说，the floor framing system in one of the adjacent buildings…remain intact.C不是文章表达的内容。D在文中提到，但不是a surprising discovery .只有B是正确答案。
5 D选项A的内容是正确的，根据是本段最后一句(“…develop new ones”)。选项B和C的内容也是正确的，根据是本段最后两句(关键词是applicable和transfer)。只有D是答案。因为Reinhorn没有说：blast engineering emerges as a new branch of science。
