This question asks which list of photographers assigned to Thorne cannot work.
First, remember that if a situation isn’t forbidden, it’s allowed. As long as a scenario doesn’t violate any rules, it’s fine! So you have considerable liberty in making scenarios to test whether answers are possible.
You should also use past scenarios to speed things up. For instance, this scenario from the setup shows that A is possible:
G was the only remaining option in the above scenario, and it’s definitely possible to place G in T.
A was the only answer without K in T. That simplifies the remaining scenarios. As long as K is in T, the game is open ended. You just have to obey these three rules:
- FH together, somewhere.
- LM apart.
- If G is in S, L is in T.
B is CORRECT. To see why, consider who is in S. B places four photographers in T. Each group needs two photographers, so that means only G and L are left to place in S. But rule 3 says that if G is in S, then L is in T.
This scenario proves that C is possible:
This scenario proves that D is possible:
This scenario proves that E is possible:
C, D and E are basically the same. The placements in T violates no rules, and you can (and must) legally place FH in S.

For a question like this, would you test out B-D? I know why B is the right answer, but wondering what your process would look like. Thanks!

So, two things:
1. If you identify B, know why, then you don’t need to test C-E. Instead, you can glance at them, check they don’t seem obviously correct, and move on’
2. C-E are all very similar, with FH in S. It’s easy enough to draw one, then shuffle around the things in T to match the answer
Hope that helps! I’m assuming you meant C-E, let me know if it was actually B-D.

Wouldn’t an easier, or rather quicker, way to spot the error in answer B be to notice that it violates rule 4 (whereby if K is not assigned to Thorne University then both H and M must be)? Unless I misread the question and by lucky accident got it right, I figured Knutson, Heideck (+Frost) and Mays could never be grouped together at Thorne University.
