By adding the new rule, we get this diagram.
This doesn’t seem like much of a deduction. But it eliminates answers C, D and E!
C: H on the second day is now full
D: S’s second day has to come after Y, not T. So S can’t test J on the second day.
E: T can’t test G, because both Ts have been placed.
The following diagram proves B is CORRECT.
And this diagram shows why A can’t be true. There’s no place to put Y on the second day. Y can’t test J.
The trick to solving these questions is to eliminate answers. Once you realize the local rule eliminates C, D and E, you can take a bit of time to draw diagrams and decide between A and B. There’s no other shortcut. Diagrams let you understand how everything fits together.
For example, the diagram that proves R can’t test H on the first day should draw itself, once you try putting R there and see what other rules are affected. If you’re not sure how I got that diagram, recreate it yourself. It’s the best way to learn.
