Q13

[soyeonjeon]

I was unprepared for this problem in general.
Now I do not get 13, 14 and 16.

What would be the contrapositives of the first two rules? I would assume that its contrapositive the first rule would be: if the moderates voted differently from the two conservatives and at least one liberal. I would assume that the contrapositive of this rule would NOT be that if the two moderates did not vote the same way..then..bla.
But I'm thinking that I might be wrong, which is why I am not able to solve 13 or 14 or 16. Could you also please explain if there is a way I can understand the first two rules faster? If not, you don't have to comment on this one.

For 14, I do not see how to solve it other than to try to disprove every answer choice as indicated in one of the comments.

For 16, I do not see how we get narrowed down to two possibilities as mentioned in one of the comments.

I really do not understand this problem in general and help would be highly appreciated.
Thanks in advance.

I answered the other questions in the general diagram thread for this game. I will address #13 here though.

We know, given the information in the question stem, that the contrapositive has been triggered. The 2 M's are separated.

So we know this for right now, and I will pretend that we did not make the L inference.

M _ .... M C

So we have LLL and C left to place.

In that situation, I would go to the answer choices. It is a could be true question. I do not want to go into a gauntlet of what seems to be a number of valid orderings.

A) This answer choice is forcing you to put the 2 M's together. This is attempting to force the rule to trigger. Having only 2 L's in and no C's in would force an L and both Cs to vote the same way, which would force the two M's together. This cannot happen.

B) Seems very plausible initially. Having 1 C and 1 L vote for. I will start with what we know.

M _ .... M C

C M L .... M C L L

This works. The LLL rule does not trigger. The CC and at least 1 L does not trigger. This is it.

C) Direct violation of the LLL rule.

D) We know from the rules that at least one C votes against.

E) Same as D.
