No3-2sectionB的短文，粘在下面了
Chimps and children, gulls and Greeks—the ethologists go their merry way, comparing bits of human cultural behavior with bits of genetically programmed animal behavior. True, humans are animals; they share certain anatomical features with other animals, and some items of human behavior may seem analogous to the behavior of other animals. But such analogies can seriously mislead if we fail to look at the context of a particular item of behavior. Thus one ethologist compares the presentation of a twig by a cormorant with gift-giving in humans. Yet the cormorant’s twig-presentation simply inhibits attack and is comparable to other appeasement rituals found in many species. Human gift-giving differs in form and purpose not only from culture to culture, but within the same culture in various social contexts. Everything significant about it derives from its social context. Thus, ethologists can accomplish little—beyond reminding us that we are animals—until they study humans as cultural beings.
题目：
The author believes that gift-giving in humans
(A) is instinctive behavior
(B) is analogous to appeasement rituals in other animals
(C) is not an appropriate subject of study for ethologists
(D) must be considered within its social context to be properly understood
(E) may be a cultural remnant of behavior originally designed to inhibit attack
答案是D，我一开始也选的D，虽然有绝对词must，但是可以找到和原文Everything significant about it derives from its social context中的everything对应。

但是这句Yet the cormorant’s twig-presentation simply inhibits attack and is comparable to other appeasement rituals found in many species，我就理解成既然拿二者作比较就肯定是有相似的，而且还有个simply，就觉得可能原始时候人也是有这个特点的，只是后来因为社会环境改变了。纠结……请好心的朋友们帮忙指点一下吧
