Read this excerpt from Through the Looking-Glass by Lewis Carroll. It was not a very difficult question to answer, as there was only one road through the wood, and the two finger-posts both pointed along it. “I'll settle it,” Alice said to herself, “when the road divides and they point different ways.”

But this did not seem likely to happen. She went on and on, a long way, but wherever the road divided there were sure to be two finger-posts pointing the same way, one marked “TO TWEEDLEDUM'S HOUSE” and the other “TO THE HOUSE OF TWEEDLEDEE.”

“I do believe,” said Alice at last, “that they live in the same house! I wonder I never thought of that before—But I can't stay there long. I'll just call and say ‘how d'you do?’ and ask them the way out of the wood. If I could only get to the Eighth Square before it gets dark!” So she wandered on, talking to herself as she went, till, on turning a sharp corner, she came upon two fat little men, so suddenly that she could not help starting back, but in another moment she recovered herself, feeling sure that they must be.

Which detail from the excerpt best reveals that things in the looking-glass land are not the same as in the real world?

A. Both signposts point in the same direction, even when the road splits in two.
B. Alice continues to travel down the same road until she comes to a split in the road.
C. The brothers Tweedledee and Tweedledum live together in the same house.
D. The two little men stand together by the side of the road as Alice turns a sharp corner.
