Q5

[jennifertrimo]

I am unsure how letters B, D, E don't work for this question as well? Can't the order be as follows: S W Y T U R ?

It CAN, but it doesn't HAVE to. The question is what MUST be true.

(B), that U is in slot 5, must be true. (And that is the right answer, by the way.)

(C) (D) and (E) all could be true but don't have to be.
