Mercury, one of the deadliest toxins, makes up approximately fifty percent of the amalgam used by dentists in sliver fillings. The effects of acute mercury poisoning are known-kidney failure, muscle tremors, memory loss, and even death. It is clear that responsible dentists should remove all of the patients silver fillings and replace then with filling of plastic composites. Which of the following, if true, most strengthens the author's argument? (A) Sliver fillings gradually corrode and small amounts of mercury leak from the amalgam. (B) It is difficult to measure the amount of mercury in a person's body. (C) Some patients have more than one filling per tooth. (D) Mercury poisoning produces a range of subtle but distinctive symptoms. (E) The materials for plastic composite fillings are readily available to dentists.
这道题目选A是肯定没错,不过因为我后来第二遍做题的时候又深入想了一下觉得:是否是该题目的问法是strengthens the author's argument,那么把argument理解为premise+conclusion,即argument是指一个推理到结论的过程,而不单指一个结论,所以要符合LOR的规则呢?如果题目问法只是说which one to strengthen the author's conclusion的话,那么E是否也可以是一个答案呢?因为毕竟只是support题,只要对conclusion起到一定的support作用就可以了。
I picked (E). My reasoning is a little odd (using an anology): If I am a responsible doctor and I have a terminally illed paitent (say has AIDS). I want to cure the patient, but the the cure is just not avialble.

But the passage doesn't mention if Mercury is available. I think, as for your anology, A is the premise of E
