Why is A incorrect. If we put a Restaurant on spot 1, then the other restaurant must be in either spots 4 or 5. If we put the restaurant in spot 7, then the other restaurant must be in either spot 3 or 4....therefore, no matter where you put the "end of the row" restaurant, the other one must be in spot 3,4, or 5....so why is A wrong?

Hi, Jorge -
The problem with answer A is that the implication goes in only one direction. Yes, if the restaurants are separated by at least two businesses, then one of the restaurants must be in space 3, 4, or 5. However, it is possible for a restaurant to be in space 3 or 5 without satisfying the constraint that the restaurants are separated by two businesses, e.g., in the ordering: R T R V S O P. Therefore [A] is not equivalent to the original constraint in terms of its effect on the ordering.
Hope this helps! Please feel free to post again if you have more questions.
Best,
Lyn
