From Professor Barbara"s experiment, we can learn that______.
A．people increase the number of calories they eat per day and gain weight
B．the "low fat" yogurt group ate less calories later than the other group
C．two groups ate the same amount of yogurt
D．people who eat low fat yogurt will not gain weight
参考答案
正确答案：A
解析：事实细节题。文章第三段第二、三句提到“When we add them to our diet,... was born out in...”，即当我们把不含脂肪的食物增加到我们饮食中时，实际上我们同时也就增加厂每天摄人的卡路里的数量，就会增加体重。这已被巴巴拉教授的研究所证明。下文接着就叙述了这位教授对两组妇女的实验，因此可知，这个实验是为了证明前面的理论，故应选A。
