I would also like to know why E would be wrong tooSkylar on August 9, 2020
@ankita96, happy to help!We are looking to replace the existing rule that L and O cannot go on the same day (Rule #3).
(A) "J and K must go on the same day" is correct. When this is the case, we have M and N on one day (Rule #2) and J and K on the other. This leaves only one remaining spot open on each day, one for L and one for O. Therefore, L and O will never be on the same day as each other.
(D) "J and M cannot go on the same day" is incorrect. All we know from this is that M and N go on one day (Rule #2) and J is on the other. We are never told that J and K must go together here. It would still be possible to have L and O together in the following scenario, so (D) is not an accurate rule replacement:
1: J M
2: L N
3: O K
T F
(E) "K and N cannot go on the same day" is incorrect. Similar to (D), all we know from this is that M and N go on one day (Rule #2) and K is on the other. It would still be possible to have L and O together in the following scenario, so (E) is not an accurate rule replacement:
1: J L
2: M O
3: N K
T F
Does that make sense? Hope it helps! Please let us know if you have any other questions.
