This Question is asking us which can be the "list" of sections in aisle 2. When a question asks only for a "list" of items/people/ideas/etc that can go in a given position, it is asking us which of the sections could/could not go in that position together, at the same time. When a question asks something along the lines of "which of the following items, any one of which could go in X position" it is asking which of the items could EVER go there, not necessarily at the same time. Note that for this latter question type, it could be phrased as "a list, any one of which." Reading the question stem carefully can help, but generally, without phrasing to the effect of "any one of which '' the question will be asking how many/which of them can go in that position together.
