Where each photograph is hung is fully determined if which one of the following is true?

Why not E?

If we place magnolia third, we also figure out where everything belongs. I, L, M, H, G, K, F it breaks none of the rules. We have our IL block together and our GK block together. We have H before K. We have fence last. I was so sure that I was right, can someone please explain?

@hfatima1, happy to help!

Although the scenario you proposed is valid and does not violate any rules, it is not the only valid scenario that we can create when we place M third. This is what makes (E) incorrect.

The question asks which answer choice would fully determine where each photograph is hung. In other words, we are looking for an arrangement that must be true, not just one that could be true. While (D) only leads to one possible arrangement, (E) leads to multiple possibilities.

You suggested the order ILMHGKF. How did you choose this order over LIMHGKF, for example? Both are valid arrangements that place M third and do not violate any rules. Since multiple such arrangements exist, (E) is incorrect.

Does that make sense? Please let us know if you have any other questions!
