which of the following most logically completes the passage?

Concerned about financial well-being of its eaderly citizesn, 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 of financially than they wer 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 all0time high
e. In runagia children typically supplement the income of elderly parents, but only by enough to provide them with a comfortable living

答案说是E,但我怎么看哪个选项都说不通啊？

Iljiajia

e 选项应该说的是孩子们的资助才是主要的经济来源，政府提供的退休金占比例很小，所以占很小比例的东西即使有了不大（文中说的是20%）的变化，那么对整体的影响也是很小的。

希望我的理解是靠谱的
