Q23

Hi there,

Could someone please explain this question? Since it's conditional I expected it to come fairly easily, however I haven't been able to see why C is the correct answer.

Thank you!

Sure! This one is tricky and takes some work with the conditional diagram. (You might be able to speed things up using the frames in the diagram post for this game, but I just worked it out.)

The condition still give us quite a few moving parts, so I first framed it out like this (no reason this was first, just wanted to start somewhere by splitting up G and H):

just 5: G L
both: S R
just 10: H V

Since it's a must be question, you can't pick an answer based on one frame, but you can eliminate any answers that this frame proves don't always have to be true. That's (A) and (D).

Next frame I switched G and H (and with them V and L, cause of the HL rule):

just 5: H V
both: S R
just 10: G L

That eliminates (E).

Next frame I tried making V one of the both elements instead of R, cause the remaining answers were about V and R:

just 5: G L
both: S V
just 10: H R

That eliminated (B), leaving (C) as the answer.

This is kind of a lot of work for a conditional question, but sometimes it happens. And the first two frames are basically mirrors of each other, so pretty quick to work out. It seemed easier here to frame and focus on eliminations rather than testing each answer, since splitting up G and H narrows other elements as well.

Hope this helps.
