Example 1 Question 7

In the example at time 16:00, C is dismissed where G is placed in the 4th time slot because that still left 2 slots open for LO. However if G is fourth, and P is placed 7th, placing LO in the 5/6th spot would not work because N must come after L and O. So then the only spot where L and O can go is 2nd and 3rd. In the explanation this is not gone over and the answer chosen is D which also seems correct to me

@RyanCamp,

Happy to help.

The problem with (C) is that if we put G 4th, then P can go in 1 or 7.
This means that LO can go in 2 and 3 or 5 and 6, so O's position is
not completely determined if G is put in 4th. This is why (C) is
incorrect.

Does that make sense? Let us know if you have any other questions!

This makes sense but what you said should be commented on. Since during testing I would run both models to assume correctness.
