Which of the following most logically completes the argument?
Last year a higher percentage of workers received salary bonuses in the south of Breeland than in the north. Moreover, of those workers who did receive a bonus, a higher percentage in the south than in the north saved part of it. Clearly, therefore, a greater number of workers in the south of Breeland than in the north saved part of the bonuses they received last year, since __________.
(A) the per capita income in the north is lower than in the south
(B) bonuses received by workers in the south were smaller, on average, than
bonuses received by workers in the north
(C) the unemployment rate is no higher in the north than in the south
(D) there are about the same number of workers in the south as in the north
(E) workers in the south are older, on average, than workers in the north

Science journalist: A study led by Dr. Elaine Hardman shows that consuming walnuts reduces the risk of breast cancer in at least some types of mice. The study compared the effects of a typical diet and a diet containing walnuts. During the study period, the group whose diet included walnuts developed breast cancer at less than half the rate of the typical-diet group. In addition, the number and sizes of tumors were significantly smaller.
Which of the following would, if true, most undermine the journalist's reasoning?
(A) The mice used in the study received the walnuts directly as food and indirectly through their mothers when they were in utero and while they were nursing.
(B) The amount of walnuts in the daily test diet equates to about two human servings of walnuts.
(C) Walnuts contain multiple ingredients that, individually, have been shown in other studies to reduce the risk of cancer or slow its growth.
(D) In the study’s mice, the walnut-containing diet changed the activity of multiple genes that are relevant to breast cancer in both mice and humans.
(E) To keep total dietary fat balanced in the mouse groups, unhealthy fats that lower resistance to disease were reduced by an amount equal to the amount of healthy fats added by the walnuts.

1、奖金比例：南方比北方高，有奖金的工人中存钱比例：南方比北方高，所以存钱人数南方比北方高。
填空题，立论考虑gap搭桥。
人数差不多的情况下，才能得到结论，直接选D。

2、现象：吃核桃的老鼠比普通饮食的老鼠得乳腺肿瘤的概率低且肿瘤小，原因：吃核桃降低乳腺癌风险。
问weaken
思考：果因论证，考虑他因削弱，别的原因导致这个现象

A：老鼠要么是直接吃核桃，要么是通过母体传播。讨论怎么获取的核桃，与原因无关。
B：实验中老鼠吃的核桃是人类的两倍。方向反。
C：核桃在其他研究中显示可以降低癌症风险。方向反。
D：核桃改变了跟癌症相关的基因。方向反。
E：不健康的脂肪（引起疾病）被健康脂肪（核桃）替代。正确，他因削弱。

选E。

Clearly, therefore, a greater number of workers in the south of Breeland than in the north saved part of the bonuses they received last year, since __________.
(A) the per capita income in the north is lower than in the south（无关）
(B) bonuses received by workers in the south were smaller, on average, than
bonuses received by workers in the north （反）
(C) the unemployment rate is no higher in the north than in the south（无关）
(D) there are about the same number of workers in the south as in the north（数量差不多，题目中百分比之间有比较）
(E) workers in the south are older, on average, than workers in the north （年龄无关）

-->A study shows that consuming walnuts reduces the risk of breast cancer in at least some types of mice.
Which of the following would, if true, most undermine the journalist's reasoning?
(A) The mice used in the study received the walnuts directly as food and indirectly through their mothers when they were in utero and while they were nursing.（和怎么进食方式无关，而且题目说是diet，没说母亲怀孕的问题）
(B) The amount of walnuts in the daily test diet equates to about two human servings of walnuts.（和量也无关）
(C) Walnuts contain multiple ingredients that, individually, have been shown in other studies to reduce the risk of cancer or slow its growth.（支持）
(D) In the study’s mice, the walnut-containing diet changed the activity of multiple genes that are relevant to breast cancer in both mice and humans.（支持）
(E) To keep total dietary fat balanced in the mouse groups, unhealthy fats that lower resistance to disease were reduced by an amount equal to the amount of healthy fats added by the walnuts.（可能是把不健康的fat移除导致试验成功）
