23. Asbestos, an almost indestructible mineral once installed as building insulation, poses no health risk unless the asbestos is disturbed and asbestos fibers are released into the environment. Since removing asbestos from buildings disturbs it, thereby releasing asbestos fibers, the government should not require removal of all asbestos insulation.
Which one of the following, if true, most strengthens the argument? (A) Asbestos poses far less risk to health than does smoking, drug and alcohol abuse, improper diet or lack of exercise. (B) Asbestos can post a health threat to workers who remove it without wearing required protective gear. (C) Some kinds of asbestos, when disturbed, pose greater health risks than do other kinds. (D) Asbestos is inevitably disturbed by building renovations or building demolition. (E) Much of the time, removed asbestos is buried in landfills and forgotten with no guarantee that it will not be disturbed again.
答案是e ,我选了b 。我看不明白为什么e是答案,原文要强the government should not require removal of all asbestos insulation. 这个insulation得意思 . 我在b里就找到了阿,其他哪个说的有insulation的意思了? :(
