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:E
我选的D。看过Lawyer的解释,很遗憾还是没懂。我认为D对的原因是renovation和demolition我认为是说对building整体处理,从而加强结论不需要removal…(有点牵强)。但E呢?怎么加强了?不还是removed了吗?No guarantee that it will not be disturbed again又起到什么作用?
disturb + fiber release = risk
D , only get disturb, not sure whether fiber will release.
E, removed materials both disturb and release fiber, (Since removing asbestos from buildings disturbs it, thereby releasing asbestos fibers) , so , causing rish.
remove itself will guarantee the risk.
早上再一看就明白了,当时为什么不选E,看来是晕了。
谢谢,hedonism555
