Q7

[VendelaG465]

Can someone please explain #7? I picked B. Aren't F & P the only letters that can be first?

From our first two rules,

F - J
F - H
and
N - T
J -T

it looks so far like J, H, and T could never go first. (So only F, N, and P are in the running)

The last rule says that P is before H-and-N
or P is after H-and-N.

So P could also go first.

Since three people (F, N, P) can all go first, the answer is (C).

Here are some examples of each of them going first.
F H N J T P
N F J T H P
P F N J T H
