Generally scientists enter their field with the goal of doing important new research and accept as their colleagues those with similar motivation.  Therefore, when any scientist wins renown as an expounder of science to general audiences, most other scientists conclude that this popularizer should no longer be regarded as a true colleague.

The explanation offered above for the low esteem in which scientific popularizers are held by research scientists assumes that

(A) serious scientific research is not a solitary activity, but relies on active cooperation among a group of colleagues
(B) research scientists tend not to regard as colleagues those scientists whose renown they envy
(C) a scientist can become a famous popularizer without having completed any important research
(D) research scientists believe that those who are well known as popularizers of science are not motivated to do important new research
(E) no important new research can be accessible to or accurately assessed by those who are not themselves scientists

其实发现对假设题最郁闷了，都说取反削弱结论，可每个选项取反后发现和解困一点关系也没有，我选的b，取反是“倾向将他们嫉妒的人当成同事，”那不就是削弱结论吗？
大牛们。。。。不吝赐教了。。。。

ASSUMPTION，就是找missing piece或logic gap了
scientists- regard someone motivated by the goal of important research as colleagues 推到 popularizer should no longer be colleague -- 中间是少了一环 -- popularizer not motivated to do important research
所以选D

不是大牛，回答一下。
similar motivation（条件）------accept as their colleagues （结果），即：no similar motivation（条件）----not accept as their colleagues （结果）.
而题目又说scientist wins renown （条件）------  not  accept as their colleagues (结果)

所以 no similar motivation与scientist wins renown 相联系，成为题目的假设。
没看出题目有提到嫉妒这层意思

这道题是前提结论结构，选D是因为前后搭桥梁

GMAT渣渣路过，回答一下，顺便整理一下知识。

文中提及，一个scientist要被同行认可为colleague，条件有二：(1): doing important new researches. (2): similar motivation

换句话说就是：一个 scientist 有 important new researches 和 similar motivation，就会被同行认可是 colleague。

它的否命题就是：一个 scientist 没有 important new researches 和 similar motivation，就会被同行认为不是 colleague。

而文中要conclusion的是：popularizer should no longer be regarded as a true colleague。

说到这里要想说的是：popularizer 不做 important new researches 和没有 similar motivation

前面的大大们提到assumption是一个桥梁，那么这个桥梁我觉得要应该包含 “popularizer 不做 important new researches 和没有 similar motivation” 系类的信息。

在选项中：
(A) serious scientific research is not a solitary activity, but relies on active cooperation among a group of colleagues （无关）
(B) research scientists tend not to regard as colleagues those scientists whose renown they envy 没提及
(C) a scientist can become a famous popularizer without having completed any important research 这个比较接近
(D) research scientists believe that those who are well known as popularizers of science are not motivated to do important new research 这更接近
(E) no important new research can be accessible to or accurately assessed by those who are not themselves scientists 没提及

答案为D

个人感想：
从答案倒推的出来的东西，之适用于第二次做这道题目，遇到别的题目，我也只有错得飞起，我都不知道怎么办了。
