寒霜的眼泪

sally believed that each individual is responsible to choose one course of action over another one, that it is the choice that gives value to the act, and that nothing that is not acted upon has value.

正确答案that each individual is responsible for choosing one course of action over another,

想问的是一个错选选项：that eac individual is responsible, choosing one course of action over another,

解析给的错误原因是改变句子重心，我觉得是不是因为responsible后面一定要接for 或者to（或者可以直接主系表，接responsible，没有见过）这个更明显的错误。

寒霜的眼泪

For members of the 17th-century ashain nation in Africa, animal-hide shields with wooden frames were essential items of millitary equipment, a method to protect warriors against enemy arrows and spears.
A a method to protect
B as a method protecting
C protecting
D as a protection of
E to protect

答案是 C 不解的是E选项to protect为什么就不能选呢？是不是说只有前面是动词的才可以呢，答案给的解析是sth is a equipment是状态，不能接表目的的词，应该是动词的目的。
是不是可以这样说：he kills all the assasins,  to protect the president. 像这样带实意动词的才能用目的状语

谢谢啊
