premise: A shopping center has exactly seven spaces—space 1 through space 7—arranged in a straight row. Seven businesses—an optometrist, a pharmacy, two restaurants, a shoe store, a toy store, and a veterinarian—will be located in the shopping center, one in each space.

The two restaurants must be separated by at least two other businesses. The pharmacy must be next to either the optometrist or the veterinarian. The toy store cannot be next to the veterinarian. If the shoe store is in space 2, which one of the following could be true?
hypothesis: The pharmacy is in space 1.
