10. Even if a crime that has been committed by computer is discovered and reported, the odds of being both arrested and convicted greatly favor the criminal.

Each of the following, if true, supports the claim above EXCEPT:

(A) The preparation of computer-fraud cases takes much more time than is required for average fraud cases, and the productivity of prosecutors is evaluated by the number of good cases made.

(B) In most police departments, officers are rotated through different assignments every two or three years, a shorter time than it takes to become proficient as a computer-crime investigator.

(B) In most police departments, officers are rotated through different assignments every two or three years, a shorter time than it takes to become proficient as a computer-crime investigator.

(C) The priorities of local police departments, under whose jurisdiction most computer crime falls, are weighted toward visible street crime that communities perceive as threatening.

(D) Computer criminals have rarely been sentenced to serve time in prison, because prisons are overcrowded with violent criminals and drug offenders.

(E) The many police officers who are untrained in computers often inadvertently destroy the physical evidence of computer crime.

答案是D，偶觉得D是加强而不是except啊。

文中后半句the odds of being both arrested and convicted greatly favor the criminal理解是说罪犯被逮捕和被定罪的机会都对罪犯有利，即是这种罪犯至少不会像其他的罪犯一样受罚。偶选的C。还请NNs 指点~

唔，那还是应该选C咯。

还有一题更郁闷：

3.

Mayor of Plainsville: In order to help the economy of Plainsville, I am using some of our tax revenues to help bring a major highway through the town and thereby attract new business to Plainsville.

                

Citizens' group: You must have interests other than our economy in mind. If you were really interested in helping our economy, you would instead allocate the revenues to building a new business park. Since it would bring in twice the business that your highway would.

                

The argument by the citizens; group relies on which one of the following assumptions?

                

(A) Plainsville presently has no major highways running through it.

                

(B) The mayor accepts that a new business park would bring in more new business than would the new highway.

                

(C) The new highway would have no benefits for Plainsville other than attracting new business.

                

(D) The mayor is required to get approval for all tax revenue allocation plans from the city council.

                

(E) Plainsville's economy will not be helped unless a new business park of the sort envisioned by the citizens' group is built.

                

答案是B，偶怎们看都不明白B为啥是前提。偶选滴E.

以下是引用uustar在2009-1-31 7:45:00的发言：
偶觉得，题目是说，计算机罪犯被逮捕和被定罪的几率小，d说的是很少被判决到监狱里服刑，这个和不被定罪是两码子事吧，不能作为增强。c也是说警察更注重的是切切实实看得到的危害社会的犯罪，而计算机犯罪不属于这种（比较隐性）。偶随便说的，不对的地方大家讨论。。。

dear,你说的不能作为增强不就是不加强么？文章的问题就是问except 啊。 C说的计算机不属于这种可见的犯罪所以警察不重视，那么这个就support了文章的结论了呀,和问题是相反的呀
