Question 3

Why is it that C is not the correct answer since the rule says that if Lentils are added last then mushrooms must be third?

That would be incorrect because L being last is your necessary condition.

M3 ==> L6
not L6 ==> not M3


The existence of the necessary condition tells you nothing.

Hope that helps! Please let us know if you have any other questions.

LO must precede N, however, and it appears in the case of the second "LO" option on option C there would be no room for N.

Im not sure if were referring to the same problem but I think we are (16m:12s of the video).

I had this same question but I realize now why we can eliminate it answer choice C to question 7 on the first set of walkthrough problems. When placing G in the fourth position in the hypothetical, P can either go to 1 or 7, IF it goes to 7, then we can apply the first and second rule to know that LO cannot go 56, but its important to consider that P can also go to 1, which would not completely determine where O would go, we would be left with position 3 and position 6 as possibilities, which is why answer choice C does not sufficiently restrict/determine O
