This is the way I see question 15:

If you look at the frames in the diagram by mshermn, In order to have a COMPLETE list of film buffs who do not see the H film according to the answers, G,I,R are needed which is stated in answer b. Rule out answers d and e because Y can see the film H in frame 2 and if you take answers a and b still one film buff is needed to not see H. Therefore ruling out only 2 film buffs is incorrect because in order for the list to be COMPLETE 3 are needed to not see the film.

I got this question wrong, too; this is how I see it, though:

We have two templates - that is:

F has 2 people;
H has 4 people; and
K has 1 person.

or

F has 1 person;
H has 2 people;
K has 4 people.

The question asks: "which one of the following could be a COMPLETE AND ACCURATE list of the film buffs who DO NOT see the Hitchcock film?

Well, we know from both templates that either 2 or 4 people must view the H film.

This also means that any complete and accurate list of people who do not view the H film must include either 3 or 5 people.

Since none of the answer choices include 5 people, the correct A/C must include 3 people who do not view the H film. It is, after all, asking for a complete and accurate list.

Thus, our attention should be directed to template 1:

F has 2 people: I/M + G/R...
H has 4 people: Y, V, L, ? ...
K has 1 person: ? ...

Therefore, (A) and (B) should be quick eliminations, as they only include 2 people.

(D) can be quickly eliminated because VY must view the H film together under this template. It also includes Y but not V; this implies Y does not view the H film, but V does...

(E) is quickly eliminated because VY must view the H film together under this template.
