在做新GRE阅读逻辑10套中，遇到几个问题自己怎么也想不通，总觉得答案似乎有问题。在这里列出来：
练习6
第7题，In the country of Laurelia, legal restrictions on the sale of lock-picking equipment were relaxed ten years ago, and since then Laurelia's burglary rate has risen dramatically. Hence, since legally purchased lock-picking equipment was used in most burglaries, reintroducing strict limits on the sale of this equipment would help to reduce Laurelia's burglary rate.
Which of the following, if true, gives the strongest support to the argument?
答案 D) Most lock-picking equipment used in Laurelia is fragile and usually breaks irreparably within a few years of purchase.
我选 E) The introduction five years ago of harsher punishments for people convicted of burglary had little effect on Laurelia's burglary rate.

第3题，Amusement rides at permanent fairgrounds are dismantled once a year for safety inspections by independent consultants. Traveling fairs, which relocate each month, can slip past the net of safety inspections and escape independent inspection for several years. Therefore, the rides at traveling fairs are less safe than the rides at permanent fairs.
Which of the following, if true about traveling fairs, most seriously weakens the argument?
答案 (B) their managers have less capital to spend on the safety and upkeep of the rides than do managers of permanent fairs.
我选(A) Before each relocation, the operators dismantle their rides, observing and repairing potential sources of danger, such as worn ball bearings.
第9题，Authorities in California required drivers to use their headlights on a certain road during the daytime as well as at night and found that annual accident rates on the road fell 15 percent from the previous level. They concluded that applying the daytime rule statewide would lead to a similar reduction in accidents.
Which of the following, if true, most strengthens the authorities' argument?
答案 (A) Because an alternate route became available, the volume of traffic on the test road decreased during the test period.
我选(E) The test road was selected to include a great variety of the sorts of road conditions that drivers in California are likely to encounter.
第10题，Which of the following, if true, most logically completes the passage?
Every fusion reaction releases neutrinos. To test a hypothesis about the frequency of fusion reactions in the Sun, physicists calculated the number of neutrinos the Sun would produce annually if the hypothesis were correct. From this they estimated how many neutrinos should pass through a particular location on Earth. The fact that far fewer neutrinos were counted than were predicted to pass through the location would seem to prove that the hypothesis is wrong, except that------.
答案(E) neutrinos released in the fusion reactions of other stars also reach the Earth
我选(D) the method used to count neutrinos detects no more than approximately ten percent of the neutrinos that pass through
第11题，An economist concluded that Kregg Company deliberately discriminated against people with a history of union affiliation in hiring workers for its new plant. The economist's evidence is that, of the 1,500 people hired to work at the new plant, only 100 had ever belonged to a labor union, whereas in Kregg Company's older plants, a much higher proportion of workers have a history of union affiliation.
Which of the following is an assumption on which the economist's argument depends?
答案 (D) The company believes that the cost of running the new plant will be lower if labor unions are not represented in the workforce.
我选(E) The pool of potential candidates for jobs at the new plant included some people, in addition to those Kregg hired, with a history of union affiliation.
练习10
