1. Rainfall in the drought plagued metropolitan
area was heavier than usual for the month of
June. Nevertheless, by the first o July the
city's water shortage was more severe than ever,
and officials proposed drastic restrictions on
the use of water
Which one of the following, if true, helps to
explain why the city's water shortage was not
alleviated by the first of July?
(A) Moderate restrictions on the industrial use
of water had gone into effect in the metropolitan
area several months earlier.
(B) Because of the heavier rainfall, people
watered their lawns much less in June that they
usually do in the metropolitan area during that
month.
(C) During the drought most residents of the
metropolitan area had been informed about water
conservation methods that would help them to
reduce their water consumption significantly with
a minimal reduction in their standard of living.
(D) The per capita rate of the use of water in
the metropolitan area was slightly lower in June
that in each of the three previous months and
significantly lower that in June of the previous
year.

答案C。怎么看C也不能解释为什么下了大雨还是不能解决干旱的问题呀。我的脑子大概是锈掉了，居然第一题就错了。

Spot the question type - Discrepancy

Possible prediction

a. Too randomly to have the rainfall at the month of June, and there is no any infrastructure to deal with excess rains for the efficiently usage.

b. More people has been abusing the water than previously.

A. It does not solve the conflict why it seems to have more water but fail to solve the water shortage

B. It conflicts with the infos offered. Based on this options, we should not have any water shortage.

C. Here is a really important key point to keep in mind that " most " residents would reduce the consumption significantly with a minimal reduction in their standard of living during the drought. Most = 51-100, As a result, we can predict that 1 - 50% of the residents would " not reduce the consumption even in drought period. As the same token, without the drought now due to the heavier rainfall than previously, no one would be informed to reduce the consumption significantly, and If this could be true, then it must also could be true that people might abuse the water the fact that consequently leading to the more severe water shortage of 1st of July than previously.

* It said " Help to explain " . As long as it could support just even a little bit, it should be the right answer.

D. If this is true, we should not have any water shortage.

用國語講解下概念：

這裡有偷藏一個因果概念

因為乾旱, 所以限制用水通報, 而有（51-100)%的民眾會大量減少用水

因為乾旱的狀況未發生（大雨）, 所以沒有限制用水通報, 所以沒有民眾會大量減少用水的機率是存在的, 既然沒有民眾會大量減少用水, 那我們剛剛推測的答案點b: 民眾濫用水量的機率就有可能會發生

無因, 所以無果。
