Hanselle and Christine,
I just want to piggyback off what the others stated. It's difficult to see that G can not be placed into slot 10 during the initial set-up. two ways to attack question # 19, process of elimination or systematically go down the answer choices. If you go with the latter, then lucky for you, the first answer choice happens to be the correct answer. If you choose to narrow your options down, it'll go like this:
(A) G differ, (B) H can never go in slot 6 because g must go ahead of it,
(C) L, no reason why L can't go in 12 or 10 so not likely (you could use your answer from question 18- which places L in 10- to eliminate this) , (D) P, this is clearly unlikely, there is nothing clear cut that P can not go in 12. (E) E is also unlikely, there is no information or deduction that make it unlikely, from the onset.
Even if you couldn't 100 percent eliminate answer choices C, D, and E, if you compare them to A, your instincts should lead you to seek out A first because you already know that G can not go into slot 12 (recall G must be before H).
With this in mind, try placing G in slot 10, several inferences follow and the upshot is that it is not possible to have a scenario where G is in slot 10.
PS: one rule that is easily to forget is that Q must be preceded by H,L, or G. thus Q can never be on stage 6.
What number 19 does is also offer us new information we can now possibly utilize for the next few questions.
The new info: G can only be slotted in slot 6,or 8 n/s,
