我好同情黑人GG啊，我也是百思不得其解，NOT+WEAKEN应该是么的错得啊？

OG解释也很WIERD！if normal levels of unemployment were exceeded relatively frequently,S's argument would be unaffected.

难道是A取非后的意思是：不是RARELY＝很频繁＋一般频繁，也就是说一般失业水平偶尔超过一下，对S的结论没有影响咯。靠，这完全是根据答案想答案嘛！

LAWYER大哥能不能现身一下哈子！

这题在百思下，我有点懂了，说下心得吧。请看OG解释：Sharon’s argument assumes that people are generally similar in how likely they are to have among their acquaintances people who are unemployed. 意思也就是说，S论断的内容是人们有相似的几率在熟人中遇见失业的。也就是说R所说的90％之类不值得恐慌。A项是说一般失业水准不会超标，取非后，会超标，对结论generally similar 没有影响，顶多是遇见的失业人多点或者少点。而正确选项B取非后说到了这和地域有关，也就是说不同地域的遇见失业者的几率不同，起到了削弱的作用，故B是正确选项。谢谢，鲜花，掌声
