Answering this question quickly depends on your ability to see all the rules and how they interact.
First, draw the new rule:
I don’t quite know how to describe the process of getting the next deduction. Insight would be the right word, but that’s not a very practical. I’ll try to break it down.
M can only be in the first three places. L can only be in the final three places. This is very restrictive. When a game gives you restrictive rules, you must always keep them in mind.
The number 3 is important.
H now has three things in front of it. That means H can’t be in the first three places. That means M is in front of H, since M is in the first three places.
We get this new diagram:
L is the only one left out. L has to be in the final three places. H has four things in front of it. Therefore H is also in the final three places.
So, H, L and S are in the final three places.
But H can’t go fifth. And H goes before S. So L goes fifth, H goes sixth, and S goes seventh.
M, F and GP fill the first four spots. The only restriction is M can’t go fourth.
In practice, I often get these deductions by starting to draw diagrams. If you keep all the rules in mind when you draw diagrams, you will spot these hidden points of restriction.
So don’t worry that you don’t have any magic insight for making deductions. I usually don’t have it either. Instead, I draw, and figure things out by drawing.
D is CORRECT. L has to go fifth, not seventh.
