请教蓝皮上的一道题：）

which of the following most logically completes the passage?

concerned about financial well-being of its elderly citizens, the government of Runagiadecided two years ago to increase by 20 percent the government-provided pensionpaid 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-----

我选的是c.They buy goods whose prices tend to rise especially fast in times of inflation

答案是e. In Runagia children typically supplement the income of elderly parents, but only by enough to rpovide them with a comfortable living.

不是很明白~~~希望各位xdjm们赐教~~~~~谢谢啦！！！！！

我觉得c选项把前提给反对了，文中的前提是inflation基本可以忽略，但是c选项把这个前提给反了，那肯定是不对的。

而E是说在R这个国家老年人的收入基本是靠儿女来支持的，那么不管你国家怎么改变，对老人的生活影响是不大的。也就解释了many of them are no better off financially than they were before the increase的原因。
