请问一道托福阅读题

答案是D，但是为啥A不对呢？
======================================…

"Numerous theories are based on the idea that aggression is an inherent and natural human instinct. Aggression have been explained as an instinct that is directed externally toward others in a process called displacement, and it has been noted that aggressive impulses that are not channeled toward a specific person or group may be expressed indirectly through socially acceptable activities such as sports and competition in a process called catharsis. Biological or instinctive, theories of aggression have also been put forth by ethologists, who study the behavior of animals in their natural environments. A number of ethologists have, based upon their observations of animals, supported the view that aggression is an innate instinct common to humans."

Question- An ethologist would be most likely to study:

a, learned catharsis in a certain species of monkey

b, the evolution of a certain type of fish

c, the bone structure of a certain type of dinosaur

d, the manner in which a certain male lion fights other males lions.

Answer 1

ethologist是生态学研究者，是偏向于行为研究的。而A讲的更多是偏向心理行为的

Answer 2

animals的内在特质是catharsis，折中特质通过Aggression释放出来，
所以ethologists要研究这种现象就必须找有冲突的地方和生物
D恰恰符合这一条件（ fights ）
A不具备，从选项看，猴群并无冲突

Answer 3

ethologist 生态学家

答案应该是d, 一种雄性的狮子和另外的雄性狮子争斗的方式
