Open ended must be true questions are tricky. Often, they depend on some deduction from the setup. But this game offers no useful setup deductions.

So instead, you should read through each answer and ask: are the variables in this answer restricted, or flexible?

If a variable is flexible, then it’s highly unlikely to be a “must be true” answer, because flexible variables can go in many places.

For instance, **A **mentioned sculptures. But there are *no *rules for sculptures. So **A **is highly unlikely to be correct. This diagram disproves it:

(Under time pressure, you wouldn’t draw that diagram to disprove A. Once you see that S is random, skip the answer to look for a better candidate).

Interchangeable variables are also good candidates for elimination. For instance, G and J are exactly the same. Their only rule is that they’re after H, so they’re interchangeable with each other.

That means **C **and **D **are both wrong. Two answers can’t be right, and there’s no difference between G and J.

**B **is a likely candidate, because it deals with two restricted variables. Both H and L have a lot of restrictions. H must be before two variables, and L is after two variables. That means H can go second at latest, and L can go third at earliest. Here’s an example:

So **B **is **CORRECT, **since there’s no way to avoid putting H before L.

I found **E **difficult to disprove. But since I already was 100% certain **B **was right, it wasn’t essential to be completely sure **E **was wrong. Especially since G is an interchangeable variable, and that makes **E **unlikely to be right.

That said, here’s a diagram to disprove **E:**

I’ll explain how to make a diagram like this quickly. **E **says that W has to be before G. So to prove **E **wrong, we need to see if we can put W later or at the same place as G.

To see if that’s possible, concentrate on W and G separately. Put W as late as possible, and put G as early as possible. Don’t try to think about it in your head: draw it. If you obey the rules, you’ll get the right drawing. That’s what I did above, the diagram clearly shows that **E **doesn’t have to be true.
