Answer 1

you got total 5 books (A,B,C,D,E)
but you selected 2 books C and D for first 2 position from right to shelf
now you got only 3 books left so you can arrange them in 3*2*1= 6 ways
example -(1) you can arrange A for 3rd starting from right,B 4th starting from the right, E 5th from the right
(2) or you can change E 3rd from the right B 4th from the right EA 5th from the right
so on..
==> you got 6 different orders to arrange A,B,E
