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

OG2016-23
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

Two years ago, the government of Runagia increased by 20 percent the government-provided pensions paid to Runagians over 65.  The aim of the increase was to stimulate the economy in the rural regions of the country, where most pension recipients live.  Statistics, however, show that there has been no increase in economic activity in those regions since then, but that there has been noticeably more spending in the urban areas.
Which of the following, if true, most helps to explain why the increase resulted in the unintended state of affairs described?
A. Until the pensions were increased, many Runagians over 65 in rural regions had been receiving support from their children who live in urban areas.
B. The pensions were increased when the number of people below the poverty level in rural areas of Runagia reached an all-time high.
C. City-dwellers in Runagia rarely travel to rural regions of the country.
D. The Runagian postal system is so inefficient that it can take up to three weeks for pension checks to reach recipients in rural areas.
E. On average, the pensions were higher in rural than in urban areas before the increase.

第一题：之前很多人讨论过，这是我的解释：
http://forum.chasedream.com/thread-1154170-2-1.html

第二题：

前提（因）：政府增加了20%养老金+通胀平均5%
结论（果）：然并卵

现在是因无法推出果，要在选项里找一个前提，放在原前提和结论之间可以使结论可以成立。
C的意思就是老人们生活需要的商品的通胀高于平均通胀，结果就是政府增加了20%养老金可能刚好抵消这部分通胀，自然老人们的生活水平没有提高了。

根据Helr的分类这个应该算是“统计枚举”，讨论的范围在前提和结论中有变化。

第三题：
逻辑链不写了，意思就是：我给我爹1000元生活费每月，我住在城里，我爹住在农村，我的1000元加上政府的养老金，我爹正好够花。现在政府给我爹养老金涨了，我就不用给我爹1000元了，现在给我爹500元加上政府的养老金我爹就够花了。我现在每个月省了500元钱不用给我爹了，我手头就宽裕了，我就在我现在住的城里花呗。

也是找个前提丢在原前提和结论之间，可以让结论成立即可。

谢谢NN，选项和答案的逻辑我都能理解，只是不明白前两个题目除了E选项不同外，其他选项和题目几乎是一样的啊! 如果不是我理解错误或者漏了什么，那么为什么会出现这种情况呢？如果是按照GMAT的原则选择最优的，那么E. in Runagia children typically supplement the income of elderly parents, but only by enough to provide them with a comfortable living为什么比C. they buy goods whose prices tend to rise especially fast in times of inflation{  (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.} 更优呢？

谢谢NN，选项和答案的逻辑我都能理解，只是不明白前两个题目除了E选项不同外，其他选项和题目几乎是一样 ...

第一题：题干说了Inflation in the intervening period has been negligible，也就是这期间没有通胀。而C选项说的是they buy goods whose prices tend to rise especially fast in times of inflation，在有通胀期间的时候，他们要买的商品价格涨的特别快。C选项描述的是题干以外的范围，属于无关。

第二题：题干说 The annual rate of inflation since the pension increase has been below 5 percent，这等于是承认了有通胀这个前提。所以C选项才说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.C就是是在题干指定的范围内（有通胀）在讨论问题，是有关的，同时也是正确选项，原因楼上讲过了。

不能只看选项不看题干啊！
