100%. There are total of 30+33-1=62 books and 2+4=6 books are removed, thus 62-6=56 books are left.

On the shelf, the atlas is the 30th book from the left.

1,2,___________29,[30]
There are 29
to the left
of [atlas]

The atlas is (also) the 33rd book from the right

******************[33],32,31_______________2,1
There are 32
books to the right
of [atlas]

There is 1 atlas.

29 + 32 + 1 = 62 books on the shelf. (2 + 4) = 6 books are removed. How many left? 62 - 6 = 56.

For the number (quantity) of books on the shelf, it doesn't matter from where they are taken. There are 62 books and 6 go away. If we were asked about the new n$$^{th}$$ place the atlas held from the left or right side or both, then which side they came from, and how many were taken, would matter.

Answer A
