We're given three facts
Fact 1: Mary Anne is not the second.
Fact 2: Faye comes after Alia.
Fact 3: Alia is ahead of Mary Anne.

Let
A = Alia
F = Faye
M = Mary Anne

Using the letters assigned above will help with shorthand notation.

There are 3*2*1 = 6 ways to order the three letters. The list of possible orderings (so far) is
A, F, M
A, M, F
F, A, M
F, M, A
M, A, F
M, F, A

Here is a table showing if each possible ordering is possible or not, based on the constraints of the given facts above

Ordering	Is The Ordering Possible?	Why or Why not?
A, F, M	Yes	All three facts (see above) are satisfied
A, M, F	No	Fact 1 is false (Mary Anne shouldn't be second)
F, A, M	No	Fact 2 is false (Faye should come after Alia)
F, M, A	No	Fact 1 is false (Mary Anne shouldn't be second)
M, A, F	No	Fact 3 is false (Alia should be ahead of Mary Anne)
M, F, A	No	Fact 2 is false (Faye should come after Alia)

Every item but A, F, M is possible (based on the constraints given by fact 1, fact 2, fact 3 above)

So the only proper ordering is A, F, M meaning Alia is first, Faye is second and Mary Anne is third

Therefore, Mary Anne is the 3rd in the list
