Re: Q2
Hey, Jennifer.
I think the quick way to solve this problem would involve you linking together the 2nd and 3rd rules.
You probably symbolized the 2nd rule as:
G -- K
You may have symbolized the 3rd rule as:
GL or LG
Some people handle rules like the 3rd one by putting the GL in a box and putting a little "flipsy-doo" back-and-forth arrow pointing at the G and the L to remind themselves that it could be GL or LG.
Personally, I draw the two letters as a vertical chunk. That means, to me, that I can rotate that chunk in either direction.
So I would write it as:
G
L
(although I would have a box around it, because I like to visually reinforce chunks when I have them in a game)
No matter how we symbolize rule 3, when you're working on a numbered ordering game, you want to link together rules that refer to the same element.
Since both rules 2 and 3 refer to G (and they're both ordering rules), we want to try to link them together.
On my page, I had
G -- K
L
This means to me that the GL/LG chunk comes before K.
When we're looking at the answer choices for question 2, we want to take a quick pass through the answers before we get too lost in testing any individual one. When we hit (B) and look at our rules to see what we know about L and K, we see that (B) really must be true. We know that the GL/LG chunk comes before K because G and L are inseparable and G is before K.
Just as a further aside, if you find yourself spinning your wheels on an unconditional problem, "which of the following must/could be true/false?", then go do any conditional problems you have left (the "if" questions).
By writing out some scenarios as you work through those "if" questions, you'll have some ammunition for the question you picked. "Must be true" answers are claiming that a certain idea is ALWAYS true. You might be able to get rid of a few answer choices just by scanning the scenarios you've already attempted and finding a counterexample.
Let me know if any of this is confusing.
