Q10

Could you pls explain how to do this one?

Sure thing.

Previous work doesn't usually help here, because our previous work would only be useful if we had already done a scenario that matched one of these answers. Usually, LSAT is wise enough to avoid that easy way out.

On a lot of Grouping games, one of the last few questions has a feel similar to this one, in which you're mainly stuck doing plug and chug, and the main question to ask yourself each time is "Who's Left?" The problems with the answer choices are almost never with the people we actually see; they're with the people who are "offscreen". So to figure out what these answers are saying, we need to think about who's left and where they would go.

In this question, they're saying the two people in each answer choice will fill up column R and column T.

Since all four people need to appear at least once, that means that the remaining two people will be in column S.

(It's hard to type in columns here, so I'll just write the groups as rows)

For a "Who's Left" question, write the roster nearby the question. I would write G J M H near Q10.

(A) This one is easy to eliminate because G and J can never be together. This is superficially a dealbreaker.

(B)
r: G, M
s:
t: G, M

who's left? J and H in column s.

r: G, M
s: J, H
t: G, M

Does that work? Checking the rules, it seems fine! Pick it, and rejoice!


For posterity's sake:

(C)
r: H, J
s: G, M
t: H, J

If J is in table, M is in recliner. We're breaking that rule.

(D)
r: H, M
s: G, J
t: H, M

G and J can never be in the same group. We're breaking that rule.

(E)
r: J, M
s: G, H
t: J, M

If G is in sofa, then H is in recliner. We're breaking that rule.


Hope this helps.
