LSAT 84, Logic Game 4, Question 22, LSATHacks

This group asks who can be the only corporations to offer 5 year bonds. Unlike question 21, this offers no additional rule, so it seems very open ended. To reduce the complexity, you should try to eliminate answers. Think which rules involve 5 year bonds:

• Rule 3 says that if V has 5, S has both 10 and 5 —> This eliminates E
• Rule 1 says that H and L have different kinds of bonds. So, if one has 5, the other has 10 —> This eliminates C
• Further, H/L have at least one L between them. So the right answer has to have one of H/L — This eliminates B (and also E, again)

Only A and D are left. How to choose? Well, G has no rules, so that makes it more plausible for a “could be true”. Since R has a rule, that makes it more likely that D doesn’t work.

Actually, we saw it in the setup. If H has 5, L has 10 (rule 1). Then, R has 10 (rule 3). So, H and R can’t both have 5:

Therefore, A is CORRECT.

The elimination of wrong answers above proves it definitively, but let’s prove is a second way with a diagram. First, place 5 in G and H:

Then apply rules 1 and 3. H and L are different, and if L has 10, then so does R. That gives G, H, L and R one bond each. You can fill up S and V with both bonds, and the scenario is complete:
