Why did the researchers hire the actor?
A. To see how she would affect the participants.
B. To test if the participants could recognize her.
C. To find out what she would do in the two tests.
D. To study why she could keep her weight down.

答案： A
解析：推理判断题——推断隐含意义。根据第二段中的“To test the effect of social influence on eating habits, the researchers conducted two experiments.”可知，该实验的目的是测试社会因素对人们饮食习惯的影响；而根据后文内容可知，被雇用的演员分别打扮成很胖和很瘦的样子去拿大量的食物，研究人员据此分析实验参与者的食物摄入情况。由此推断，研究人员雇这位演员的目的是观察她会对实验参与者产生怎样的影响。故选A项。

On what basis do we "adjust the influence" according to the last paragraph?
A. How hungry we are.
B. How slim we want to be.
C. How we perceive others.
D. How we feel about the food.

答案： C
解析：推理判断题——推断隐含意义。根据最后一段中的“However, we'll adjust the influence. If an overweight person is having a large portion, I'll hold back a bit... If he can eat much and keep slim, why can't I?”可知，我们会因为对就餐同伴的看法而调节对方对自己的饮食行为的影响。若对方太胖又胃口很大，人们可能会“引以为戒”；若相反，很瘦的人胃口很大，人们则会效仿。故C项符合语境。
