请教两体语法提,画线依次为A,B,C,D
1.In every society there are norms that say individuals how they are supposed to behave. 答案是B, 是不是应该是改为individuals say 呢?

2.Xanthines have  both good and bad effects on the body, and these effects are generally determined on the size and regularity of dosage.答案是C,我觉得是D应该加the 吧?

3.the giraffe's long neck and legs are the most obvious features
that  make different from all  other animals. 答案是C,我觉得是是否是D应改成 any other animals呢? all other animals , 有这种说法吗?

谢谢
