B.    in the determination of how and when the islands of the West Indies were colonized by mammals
C.    to determine how mammals colonized the islands of the West Indies and when they did
D.    for determining when the islands of the West Indies were colonized by mammals and how they were
E.    for determining how and when mammals colonized the islands of the West Indies

答案选E，明白~
想问下大家C选项，我看了之前的讨论帖是说provide sth for sb，没有provide sth to do这个结构，那这个跟to do的逻辑主语有没有关呢？我记得好像Manhattan里有讲，to do与逻辑主语搭配必须有意义，那这里如果用to determine其逻辑主语是不是变成了mammal bones 所以不对呀？
thx！！

是的，provide to do，这里的to do要有动作的发出者，就是要有to do的逻辑主语，嘿嘿，这题我也错了~

难道E就没有逻辑主语的问题？？
