Question from Analytical Reasoning article on Khan Academy

Hi all,

I've been struggling to wrap my head around this question (i'll post below). Can anyone explain this?

"It must be true that the lowest-numbered line on which" changes to "no lower than line". . . Why is it not that F can be lines 2 or 1?

It must be true that the lowest-numbered line on which
(A) F can be assembled is line 2
(B) G can be assembled is line 3
(C) J can be assembled is line 2
(D) K can be assembled is line 3
(E) M can be assembled is line 2

(A): Does it have to be true that F can be no lower than line 2? In other words, could F be 1st?
F could be lower than line 2! We have no rules stopping F from being 1st, and for completion’s sake—though you probably wouldn’t do this on Test Day—we’ll give you an example. F could be 1st, for example if the order were: FMGSJKH. Although there are several other possible scenarios in which F can be 1st, finding just one is sufficient to determine that this choice’s statement “could be false.”
