#15 - Local

[Jon Denning]

Another Local question here for #15, with R in 2 and a Must Be True prompt.

Let's first see what happens if we put R in 2, and then find the answer that must occur from it.

If R is in 2 then V cannot be in 1 or 3 (to keep it away from R). It also means that the WZ block must be pushed towards the back of your base, since it won't fit in 1 and putting it in 3-4 interferes with S. So WZ could be 4-5, or 5-6.

Notice that space 1 is running awfully low on options at this point: R in 2, S in 3 or 4, WZ somewhere in spaces 4-6, and V away from R so space 4 at the earliest.

Who's left?

T! T must be in 1, as it's the only remaining variable!

And that's answer choice (B).

The other answer choices all present situations that either could be true—V in 6, W in 4, Z in 6—or that cannot be true—S in 4 (S 4 means the WZ block is 5-6 and leaves V in 3, next to R).
