问问大家一个推理的技术问题

clyne

举个例子吧：

For years the beautiful Renaissance buildings in Palitito have been damaged by exhaust from the many tour buses that come to the city.There has been little parking space, so most buses have idled at the curb during each stop on their tour, and idling produces as much exhaust as driving.The city has now provided parking that accommodates a third of the tour buses, so damage to Palitito's buildings from the buses' exhaust will diminish significantly.

Which of the following, if true, most strongly supports the argument?

(A) The exhaust from Palitito's few automobiles is not a significant threat to Palitito's buildings.
大家在考虑A选项时，会不会不自觉地对选项进行取非？
一个选项取非后是不是仍然是无关的？
起support作用的选项取非后是不是起weaken作用的？

For strengthen and weaken question, you do not need to do negation on each choice.

For strengthen question, the correct answer is sometimes an example used to solidify the argument. Negating it would not necessarily weaken the argument.
