求助一道逻辑题

请问下面这道题的解题思路。谢谢。

Question 12:

Which of the following most logically completes the passage?

Concerned about financial well-being of its elderly citizens, the government of Runagia

decided two years ago to increase by 20 percent the government-provided pension

paid to all Runagians over 65.  Inflation in the intervening period has been negligible,

and the increase has been duly received by all eligible Runagians.  Nevertheless,

many of them are no better off financially than they were before the increase, in large

part because ________.

A.        They rely entirely on the government pension for their income

B.        Runagian banks are so inefficient that it can take up to three weeks to cash a

pension check

C.        They buy goods whose prices tend to rise especially fast in times of inflation

D.       The pension was increased when the number of elderly Runagians below the

poverty level reached an all-time high

E.        In Runagia children typically supplement the income of elderly parents, but

only by enough to provide them with a comfortable living

我觉得是C。

多讨论。

I  choose A.

我觉得是Ｃ．本题的推理思路：

原因：１）事实：the government of Runagia

decided two years ago to increase by 20 percent the government-provided pension

paid to all Runagians over 65.  

２）事实：Inflation in the intervening period has been negligible,

and the increase has been duly received by all eligible Runagians.  

结论：many of them are no better off financially than they were before the increase

Ａ：weaken

B:  no correlation

C:  correct指出食物价格增长的比例超过了２０％的政府津贴，假设２年前１００元买２代米，２年后加２０％的政府补贴应为１２０元，但一代米已经买８０元，故结论成立

Ｄ，Ｅ：无关项

我改变主意了，选E。

主要还是题意没理解好和选项没主意看。原文中说Inflation in the intervening period has been negligible. -->通货膨胀是可以忽略的。那么C就不对了。既然通货膨胀是可忽略的，微不足道的，就不可能出现C这种情况了。C显然是陷阱。

而E：children typically supplement the income of elderly parents, but only by enough to provide them with a comfortable lives.

注意阴影部分。孩子们是补充老人的收入，但补充的结果是仅仅足够他们have a comfortable lives. 如果政府增加老人的pension的话，children就会减少他们补充的部分，也是仅仅足够老人have a comfortable live.
