Answer 1

Please someone answer it ): This is the only question I don't understand.

Answer 2

look for key words in a-d that match words in 1-4

Answer 3

So would it it be 1=D , 2=A, 3=C, 4=B ?

almost, I would switch D and C since D has the word index and C is list of different classes. I have not heard of this type of question before, so this is my best guess.
