Q8

[Jae HeeK459]

I understand why (A) is the correct answer, but I don't understand why (E) is the wrong answer.

I don't know how to transfer my diagram here but on my first tree, V is both before G and P. Plus, G is before J (J being a stray).

On my second tree, V is after both P and G. Plus, J is before G (J being a stray).

Please help!

You might have limited yourself too much during the setup phase. Try proving (E) wrong with a counterexample. Forget about your diagrams and just write a scenario in which G is before V.

I think you may have gone wrong during the setup stage, because you'd need FOUR frames, not TWO, given that rule 2 and rule 3 are each offering us two choices.

Rule 2:
G is before J and L, or G is after J and L

Rule 3:
V is before G and P, or V is after G and P

If you think of those as
Rule 2: choice A or B
Rule 3: choice Y or Z

then you'd need four frames:
A Y
A Z
B Y
B Z

That's too obnoxious for us to find useful, so most people would frame nothing or just frame rule 2 or rule 3, but not both (leaving the other rule kinda hanging out beneath each frame).

Okay, how's that counterexample for (E) coming?

If L is 6th
_ _ _ _ _ L
we know we're doing G is before J and L, so G - J.
And we have P - M from rule 1.

I'm just gonna throw them in for a sec.
P M G J _ L

Who's left? V.
V is before G and P, or after G and P. Okay, let's put him after!

P M G J V L

Read through the rules and verify that we've obeyed all of them, then eliminate (E).

Thank you for your in-depth explanations! I really learn a lot

Hi Team

Here I saw that if L is in the 6th position, then you can't have L & J -- G - so then, it has to be the second frame G -- L & J. If that's the case, then G has to come before J.

Am I missing something, or if I select A based on the above thought process, would you then recommend going through the rest of the answer choices?

Thanks again - really appreciate all the support on this game.
