Would example 3 be the best answer for this question?

Which setting would probably NOT be the
best for a book center?

1. A small table in the corner of
the room.

2. A "fort" with lots of pillows.

3. A large table in the middle of
the room.

4. A rug surrounded on three sides
with shelves and book displays.

(Thanks)!

I'd be least comfortable at a large table in the middle of the room. Most of us like to read in cozy surroundings with few outside distractions. Your choices, 1, 2, and 4 are cozy surroundings. Number 3 is too public and impersonal to make a good book center.
