Incorrect. Since the number of works isn't raised as a consideration in the stimulus, this answer is out of scope. Especially since the stimulus never talks about the relative number of works that museum-goers today look at compared to in earlier times (just because they look at each work for less time doesn't mean they look at more; they could spend less time in museums).

Incorrect. The Art Critic doesn't connect nor require the ability to snap a photo with your cell phone to the speed of moving past artworks for the argument to work, as long as either of those things establishes something about engagement.

Incorrect. The argument is about engagement, not enjoyment, and those two concepts aren't inherently related, so this answer is out of scope.

Incorrect. This answer is too specific to be correct—there's no indication that looking at photos taken of art afterwards is in any way related to engagement.

Correct. Argument or Facts:
Argument

Valid or Flawed:
Flawed

Question Type:
Strengthen with Necessary Premise

Stimulus Summary:
Most museum-goers barely look at art, take a snapshot, and go to the next piece of art. This shows that people engage with art less than in the past.

Answer Anticipation:
The conclusion here introduces a brand new concept—engagement with works of art. The premises never discuss that concept (or even define it, since it's pretty abstract and vague), so the correct answer will likely connect it to an idea in the premise. The idea that seems most related is the amount of time spent looking at the work of art, so, for a question #5 that's likely to be more direct, the answer will probably connect time spent looking to engagement.

Answer Explanation:
This answer connects the premise to the conclusion, and thus it's necessary for the argument to work. If the amount of time looking at a work of aren't isn't a reliable measure of engagement, then the Art Critic's premise doesn't establish her conclusion, and the argument falls apart.

Key Takeaway:
For early Strengthen with Necessary Premise questions, the argument will usually feature a term shift, and the terms will be connected in the correct answer.
