Passage 4 (4/63)
Efforts to explain how the pterosaurs became airborne have led to suggestions that they launched themselves by jumping from cliffs, by dropping from trees, or even by rising into light winds from the crests of waves. Each hypothesis has its difficulties. The first wrongly assumes that the pterosaurs’ hind feet resembled a bat’s and could serve as hooks by which the animal could hang in preparation for flight. The second hypothesis seems unlikely because large pterosaurs could not have landed in trees without damaging their wings. The third calls for high waves to channel updrafts. The wind that made such waves however, might have been too strong for the pterosaurs to control their flight once airborne.

我只把原稳定为需要的段落打在这里，问题就是
2.The author views the idea that the pterosaurs became airborne by rising into light winds created by waves as
(A) revolutionary
(B) unlikely
(C) unassailable
(D) probable
(E) outdated
为啥不是possible呢？因为原文给了三个架设（见上面的段落），这题问的就是对于第三个架设的态度是？我从这段看出三个的确有 each hypothesis has its difficulties  原文只是说第二个是seems unlikely
所以第三个（题目）架设就该是既有缺陷又有正确的地方（因为要不然写在这里还有意义吗)所以我选D
可答案为啥选B?
难道就因为difficulities吗？

《In the pursuit of happiness》里Chris跟他儿子Christopher解释possibly和probably的区别:

probably means there is a good chance to be true
possibly means it might/might not be true

这就是不选D的原因，因为那是很有可能的意思。
