读crazyrobin的神贴时遇到的问题，求大神解释

In contrast to most animals, humans are true killers; our history
is a record of destructiveness and cruelty. Do we possess some
uniquely human capacity for destruction, or does human hyper-
aggression have the same origin as benign animal aggression?
In support of the latter assumption, it can be argued that when
an animal is deprived of space, it becomes vicious and
destructive. Thus, human hyperaggression is perhaps a
result not of our increased potential for aggression, but
rather of our being exposed more frequently. This argument
forces us to analyze the human condition in history. We can infer
that modern humans have lived primarily in a “zoo” rather than in
the “wild.” In fact, most data about human nature closely parallel
observations of monkeys in crowded zoo conditions. Yet, even
when not in congested situations, humans often act
destructively and cruelly.
The two sentences in boldface play which of the following roles?
A.The first proposes a hypothesis; the second refutes the
hypothesis.
B.The first proposes a hypothesis; the second provides supporting
evidence.
C.The first presents an argument; the second points out a
contradiction to that argument.
D.The first introduces a viewpoint; the second expands on this
viewpoint.

纠结于A和C，为什么不选A？presents an argument和proposes a hypothesis的区别是什么？

Argument是指有 premise, 有 conclusion的一段逻辑论证过程， hypothesis就是一个带有结论的话不需要有任何premise
第一句bold的话前面用动物来做类比，说当动物deprive of space时候变的destructive, 一个thus直接告诉你这是个argument
而第二个bold的话直接对上述观点反驳了

做argument structure的逻辑题建议你先知道这几个概念
Premise, argument, conclusion
counter premise, intermedia conclusion

自己去查google便有这些
