45题解释中虽然没有说determing的问题，本人认为这里也值得研究研究
ing放在句末，
修饰整个句子表结果或伴随，整个句子作分词的逻辑主语
这里逻辑上可以表结果，但是不可能时这个句子决定（determine）..也只能是scientist决定
也不可能做伴随，不可能边检查边决定
修饰主句主语scientist
但是这样的话就和原文：想要表达examine和determine是一个平行的动作相违背，让determine做了examine主句的附属结构了也错

跟77上面的例子有点像。
只是个人的意见，若有错误希望大家指出谢谢了··

再追问一个问题
45
B选项 through the application也需要考虑逻辑主语问题么? 请问through在这里是prep么？
我看Tony的语法总结里需要考虑逻辑主语的结构是： prep + doing/done, svo 请问 +n也需要么？
谢谢了···
