Can you please explain why the answer is E and not D?

Hi @rmkrutz@crimson.ua.edu, thanks for your post.

Let's first examine the statements in the stimulus.
P: If the city builds the proposed convention center, several national professional organizations will hold conventions there.
P: If several *large* conventions are held in the city, the total number of visitors will of course increase.
P: If the number of visitors increases, tax revenues will certainly increase.
C: Thus, building the convention center will increase the city's tax revenues.

The assumption is stated in (E) - it's not enough that several national professional organizations hold conventions, but that several *large* conventions are held in the city. That gap needs to be bridged.

Answer choice (D) is irrelevant. Nothing in the stimulus addresses the link (if any) between current regular visitors to the city and the new convention center. The stimulus is about a possible link between the new convention center and increased tax revenues for the city.

Hope this helps! Please let us know if you have any additional questions.

But it says tax revenue will increase if the number of visitors increases?

@Aidyn-Carlson, that's true, but that's all predicated on the other premises. In order for that condition to trigger, we must know that large conventions will be held.

In order to know that large conventions will be held, we need to add that the several national professional organizations who will be holding conventions will be holding LARGE conventions. If we add this, then the conclusion follows logically from the premises.

Does this make sense? Let us know if you have any more questions!
