Citizensof Parktown are worried by the increased frequency of serious crimes committedby local teenagers.  In response, thecity government has instituted a series of measures designed to keep teenagersat home in the late evening.  Even if themeasures succeed in keeping teenagers at home, however, they are unlikely toaffect the problem that concerns citizens, since most crimes committed by localteenagers take place between 3 p.m. and 6 p.m.

这样翻译你看对不：P地的居民担心当地青少年 提高频率的 严重犯罪。作为回应这种担心，当地政府出台一项措施保证强少年在late evening的时候在家。即使 这个措施有效，也不能解决当地居民的担心，因为大部分的 犯罪发生在3-6点。

题目中提到的是两个不同的概念，当地居民担心的是啥？严重犯罪。 3-6点发生的是啥？犯罪。 B选项正是利用了这个模糊点，进一步定义了 3-6点的 犯罪 是小犯罪 不是 当地居民所担心的大犯罪。

这题问的是什么？
Weaken的是啥？作者说政府的措施不会有效。所以，要选“能起到作用”之类的，对吗？
