如果craving对选择有影响的话不就多了一个变量了吗？

第4题
(A) The craving for fatty foods does not invariably (always) result in a rat's choosing those foods over lean foods.
A选项其实是weaken了，invariably是always的意思。所以break the link了：就是说rats喜欢fatty food也不一定总是会去选择fatty food，那么本来的link：rats有更多G--> rats喜欢吃fatty food--> rats就会选择fatty food就被破坏了。
(D) The rats that preferred fatty foods had the higher concentrations of galanin in their brains before they were offered fatty foods.
原来D才是我的思路。有更多G-->会选择F，就要反过来想：不是因为吃了更多F-->有更多G，而是本来就有更多G才会导致rats选择吃F。
就是一种推理模式了：结论A-->B, strengthen：B不能推A。

第3题每个support的选项都是因果型结论的其中一种思路啊 呼呼 我把SC错题啃完后就要看CR bible，感觉太好了。
