Which of the following most logically completes the passage?

Concerned about the 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

请问C为什么错？题干中说通货膨胀率忽略不计，但是这不意味着所有物品价格都不变啊，C说老人们需要的物品价格上升，所以不就没有finacially better off了嘛？E选项说孩子给父母的钱只能让父母生活舒适，现在又多了一份政府资助，那不是应该better off了嘛？为什么有了政府资助，孩子就要减少给父母的钱了？这不是过度推测吗？

OG上有一道类似的题，答案是C：
Plan: Concerned about the welfare of its senior citizens, the government of Runagia decided two years ago to
increase by 20 percent the government-provided pension paid to all Runagians age sixty-five and older.
Result: Many Runagian senior citizens are no better off financially now than they were before the increase.
Further information: The annual rate of inflation since the pension increase has been below 5 percent, and the
increased pension has been duly received by all eligible Runagians.
In light of the further information, which of the following, if true, does most to explain the result that followed
implementation of the plan?
(A) The majority of senior citizens whose financial position has not improved rely entirely on the government
pension for their income.
(B) The Runagian banking system is so inefficient that cashing a pension check can take as much as three
weeks.
(C) The prices of goods and services that meet the special needs of many senior citizens have increased at a
rate much higher than the rate of inflation.
(D) The pension increase occurred at a time when the number of Runagians age sixty-five and older who were
living below the poverty level was at an all-time high.
(E) The most recent pension increase was only the second such increase in the last ten years.

第一个说了通胀忽略，是一个求他因的题
第二个考虑通胀，是一个部分与整体的比较题
