标题: [help] 假设题
1 Some United States psychologists have concluded that one specific set of parental behaviors toward children always
signifies acceptance and a second set always signifies rejection, for there is remarkable agreement among investigators
about the maternal behaviors designated as indicative of these parental attitudes.

The conclusion of the psychologists mentioned above logically depends on the assumption that

a.most maternal behaviors have been interpreted as conveying either acceptance or rejection.

b.the maternal behaviors indicating acceptance or rejection are exhibited by fathers as well.

c.the behaviors of fathers toward children have been studied as carefully as have the behaviors of mothers.

d.acceptance and rejection are the easiest to recognize of all parental behaviors.

e.parental attitudes are best conveyed through behaviors that the parents have consciously agreed on.

为什么不选E呢?

2 The world's annual food production slightlyexceeds the amount of food required to provide
a minimally adequate diet for the world's population. To predict that insufficient food production
will cause a hunger crisis in the future is nonsense. Any hunger crisis will result from a distribution
problem rather than a production problem.

The statement above assumes which of thefollowing?

A the world's food requirements are greaterthan they will be in the future

B Ashortfall in the world's food production can be prevented by a betterdistribution system

C The world's food production will continue to be sufficient to meet or exceedneeds.

D The distribution of the world's existing food supply will be improved in thefuture

E The world hunger crisis will not exist in the future.

请问B为什么错?

3 some geologists argue that if oil is as common in unsampled areas of the world as it is in those already sampled,
our current estimate of reserves that exist underground must be multiplied by a factor of 10,000.
From this we can conclude that we can meet the oil needs of the entire world for at least five centuries,
even assuming that future consumption grows at an accelerating rate.

To reach the stated conclusion, the author must assume which of the following?

A. it is possible to recover the oil contained in unexplored areas of the world

B. The consumption rate for oil will not grow rapidly

C. Oil will remain an important evergy source for at least 500 years

D. The world will achieve and maintain zero population growth

E. New technology will make oil discovery and drilling more feasible than ever before.

请问E为什么错呢?

THANKS!

2.文章第一句话就告诉你production比demand for adequate food要大，你不能直接推翻premise。你也可以直接negate B选项,那么就是 short fall in the world's food production cannot be prevented by a betterdistribution system，没有negate argument.楼主应该是记混了，遇到assumption的题目要么找Gap那就是加强题型，要么negate答案后能削弱的，就是答案的特征。3.A选项negate It is NOT possible to recover the oil contained in unexplored areas of the world刚好削弱，而E选项negate后没有削弱。至于第一题我也弄不清楚

第一题能不能简单点理解，就是题目中的结论是 parental ，但是条件中只有 maternal，所以选C。。。。。

我觉得这个答案B是相对好一些，假如把A选项的most去掉的话应该选A,
PS：陈向东的书上面有些逻辑题不会做，偏偏这些题有些没有解析。无语死了
