- [Instructor] Make sure
that you've already watched the set-up video, in which we
created the initial diagram that you see us using here. So the question asks if G is
the monument that was begun in 602, which one of the
following could be true? So we're looking for the
choice that is possible in the scenario, that G is second. Since we're given new information, that isn't necessarily true outside of this particular question, let's re-draw our initial diagrams, so that we can work from
it, and make deductions that are specific to this scenario only. Alright, now we can
incorporate the new condition by placing G second. That leaves M and S to be
the pair that's in 601. L has to be third, because we
deduced in the initial set-up that's the latest that L can be, and so F and H must be fourth
and fifth in some order. Now, let's evaluate each
choice, and eliminate the ones that are impossible, and select
the one that is possible. A, F was begun in 603. Well that's not possible,
because we deduced here that L has to be the
monument begun in 603. B, H was begun in 604. Now that could be true. We just deduced that
either F or H is in 604, so this our answer. In case you have questions
on the remaining choices, let's take look at them quickly. C, M was begun in 603. This doesn't work, because
we know for this question, M is in 601. D, S was begun in 603. Just like with choice C, this is false, because S is in 601. E, S was begun in 604, and
again this is impossible, because we already
deduced that S is in 601. So, B's the answer. And with a quick re-sketch
of the initial diagram, and a look at the implications of the questions new condition, we got to the answer pretty efficiently.
