A librarian has a set of eight books, including four different books about Abraham Lincoln. The librarian wants to put the eight books on a shelf with the four Lincoln books next to each other, somewhere on the shelf among the other four books. How many different arrangements of the eight books are possible?	Choose the correct choice from the following options.
A) (8!)/(4!) B) (4!)(4!) C) (4!)(5!) D) (4!)(8!) E) (4!)(4!)(8!)
You can club the four Lincoln books as one, which leaves us with four other books plus this one to think about. So, these five items can be arranged in 5! ways, and since the four books can be moved around among themselves with each combination giving us a new overall combination, we have an additional 4! ways. Therefore, the answer would be 5!*4!, which is (4!)(5!).
