Question

Each question has a statement. Pick from the options the most appropriate restatement of the given statement. Select the one which is closest in meaning to the given statement.

Perhaps the easiest way to demonstrate that cooperative behaviour in human beings has a genetic basis and is not simply culturally constructed is by observing not humans but their closest genetic relative, the chimpanzee.

1. It can be demonstrated with ease, by observing humans and their closest genetic relative, the chimpanzee that cooperative behaviour in human beings is based on genetics and is not merely culturally constructed.
2. The fact that cooperative behaviour in human beings has a genetic basis and is not simply culturally constructed can be easily demonstrated by observing not only humans but also their closest genetic relative, the chimpanzee.
3. By observing humans, and their closest genetic relative the chimpanzee, it can be easily demonstrated that the cooperative behaviour in human beings has a genetic basis and is not socially constructed.
4. It can be demonstrated with ease by observing the chimpanzee, which is the closest genetic relative of human beings, that cooperative behaviour in man has a genetic basis and is not merely socially constructed.

Answer 1

1. It can be demonstrated with ease, by observing humans and their closest genetic relative, the chimpanzee that cooperative behaviour in human beings is based on genetics and is not merely culturally constructed. => Does not seem correct ! Why we are obseriving humans here ? Original Sentence does not say that we should observe humans.
2. The fact that cooperative behaviour in human beings has a genetic basis and is not simply culturally constructed can be easily demonstrated by observing not only humans but also their closest genetic relative, the chimpanzee. => Same Argument as 1.
3. By observing humans, and their closest genetic relative the chimpanzee, it can be easily demonstrated that the cooperative behaviour in human beings has a genetic basis and is not socially constructed. => Same argument as 1, We don't need to observe humans !
4. It can be demonstrated with ease by observing the chimpanzee, which is the closest genetic relative of human beings, that cooperative behaviour in man has a genetic basis and is not merely socially constructed. => This is correct, Exact restatement !

Answer 2
