大全-18-2.    Crimes are mainly committed by the young, and for this reason merely increasing the number of police officers or expenditures on police services has little effect on reducing the crime rate. In fact, the only factor associated with a crime-rate drop is a decrease in the number of people in the community aged fourteen to thirty.
The findings above can best serve as part of an argument against
(A) the likelihood that any law enforcement program will be effective in reducing the crime rate within a short time
(B) increasing prison terms for young people found guilty of crimes
(C) introducing compulsory military conscription for people aged seventeen to nineteen
(D) raising the age at which students are permitted to leave school
(E) a community’s plan to increase the number of recreational and educational activities in which young adults can participate
这题的正确答案是A，为啥不是B呢？The findings above can best serve as part of an argument against是啥意思呢？

题目的意思是由于犯罪者主要是年轻人，因此仅仅增加警察的人数或者增加投入是没有用的，该地区犯罪率的下降是因为年轻人人数上的减少！
问题的意思是上面这个发现是下列哪一个观点的驳论.
A)法律措施在减少年轻人犯罪方面很有效
B)更长的刑期让年轻人因为他们的犯罪行为感到内疚
这样应该不会有疑惑了吧！~
