i got this answer right, but i was unsure of myself. I was down to the last 3 answers. A C or E. Answers C and E were from the same rule. I was successful in crossing out 2 wrong answers. In a situation like this how do i come to the right answer?

Hi rdee,

Crossing out wrong answers can be a great strategy. I like doing as much up front as I can. So for me, I made a local diagram, putting H in 4. Then visually I looked at what part of my rules were most likely to be an issue. The H1 conditional won't be relevant, because H isn't in 1. The sequence of L-K-F is relevant, as is the MJ block. I'm not yet sure how the F6 conditional would come into play.

Initially, I focused on the MJ block because it seems most limited. The block could either go 1 and 2, 2 and 3, or 5 and 6. I looked at each option one by one to see if it indicated something about this local condition.

If MJ are 1 and 2, that means L is 3, K is 5, and F is 6. Oh! F in 6 triggers a conditional that requires J in 3. But J is in 2 here. So MJ cannot be 1 and 2.

If MJ are 2 and 3, L would be 1, K would be 5, and F would be 6. That also triggers the F in 6 conditional, but here, J is in 3, so it's ok. This is a possible solution. I don't want to stop here though. I want to make sure there are no other solutions. This one doesn't let me know if the answer is answer choice (A) answer choice (C) or answer choice (E).

If MJ are 5 and 6, we have L in 1, K in 2, and F in 3. There! In both possible solutions, L is in 1. That's our must be true answer.

Hope that helps!
