问题 What do the researchers mean when they say the overweight dogs "go for the sure thing"?
选项 A、The overweight dogs would only eat tasty food.
B、The overweight dogs tried to maximize their food intake from the higher quality food.
C、The overweight dogs would surely eat the food placed before them.
D、The overweight dogs would wait for people to feed them.
答案 B
解析 原文说：This means，the researchers say, that the overweight canines tried to maximize their food intake from the higher quality food and hesitated to do the task when the food reward was uncertain．也就是说，超重犬不是得到什么吃什么，而是要吃好吃对，否则，它们宁可不吃。这一点和选项B完全一致，因此，答案是B。此外，还要认识canine这个单词。根据上下文，我们能够推测出canine就是dog的意思。
