I'm thinking D, because say the book "Night" it changes all the time, just like the character. As they move from concentration camp to concentration camp the character gets gloomier and more depressing and the camps are different every time. Hope this helped!
<em>The question has already been answered, but I guess you need an explanation.</em>

Answer:
<em>They are buying them for him</em>
<em />
Explanation:
To properly understand this, you need to know about the subject-object agreement.
This agreement follows:
[S] [P] [O}
<em>S: Subject represent who does an action</em>
<em>P: Predicate is what is being done</em>
<em>O: Object receives of the action.</em>
<em />
In the given words, the predicate is "buying"
So, you need to know who is buying something and what is being bought
<em>"They" -----> the subject </em>
<em>"are buying" ----> the predicate </em>
<em>"them" ---> the object </em>
<em>"for him" ---> to whom the object is being bought for</em>
The beginning starts off with "has taught" indicating a foreword. The passage also talks about past achievements and accomplishments.
