[求助]大全140,搜索过了,但没满意的答案

140. As the housing affordability gap widens, middle-income families are especially hard-hit, and these families can no longer qualify to buy homes, and rising rental rates force them to use far more than the standard 25 percent of their incomes for housing, leaving them with no equity or tax write-offs to offset the expenditures.

(A) and these families can no longer qualify to buy homes, and

(B) since these families can no longer afford to buy homes, furthermore

(C) for these families can no longer afford to buy homes, yet

(D) and these families can no longer afford to buy homes; however,（C）

(E) and these families can no longer afford to buy homes, for

为什么后面是用yet来转折,而不是递近关系,

these families can no longer qualify to buy homes和rising rental rates force them to use far more than the standard 25 percent of their incomes for housing, leaving them with no equity or tax write-offs to offset the expenditures都在讲他们的遭遇啊,为什么是转折,请正面回答

我能从反面回答么？呵呵，‘正面回答’，口气很强硬的说。

首先排除A，and these family从句子的逻辑连接上看肯定错，因为句子前后不是并列关系；其次排除B，furthermore是个副词，不能作连词用；D/E的错误类似A，可排除；余下C，未划线部分表明现实，划线部分开始讲原因，for作连词解释为：因为，可以接受；for these families can no longer afford to buy homes, yet rising rental rates force them to use 其实和中文语气表达十分类似：这些家庭已经不能...，而(转折)上涨的费率居然还迫使....，所以，转折语气在这里反而十分合适；当然，用and也不是不可以，相比转折似乎要差些。

谢谢stoneren, 你真是个好人啊! 改天有机会真得请你吃饭! 呵呵

始终觉得递近很勉强,看来只好排除绝对错误的先了,唉!

正象你说的,"居然还",竟然等在中国应该是表示递近,而不是转折啊!

真是牛人啊，如果考试时真希望也能有时间反应过来该递进还是转折

我对你用逻辑意思的方法去判断A项心存疑惑，或者说我还还没有理解到为什么你要从逻辑意思上去判断呢？什么时候应该用逻辑意思去判断呢？因为题意本身的逻辑意思有可能是这样，有可能是那样。你怎么就知道逻辑意思一定是朝你指的那个方向去呢？你能够给我一点提示吗？我现在在这方面很纠结。

I'm still confused. Just asked a native speaker to check this question and answer. I was advised that B, C or E are both correct. I also showed him the correct answer; but he insisted that furthermore could be used in this situation.

Need urgent help from any NNs! Thank you in advance!

1. 呃，如果native speaker都能做对，他们也不需要考GMAT了。

2. 正如上面所说，furthermore是个副词，句子没有连词。
