I just noticed that she also said that we know "Nader goes before Hodges", but as she points to the sequencing chart, Nader is shown as being after Hodges.

Hello @Gozi,

I think she just misspoke briefly at that point in the video by repeating Hodges twice. You seem to understand the question, as you noticed this issue in the video. The diagrams in the lesson are still perfectly valid. I'll go over it in order to clarify.

15. If James joined the firm in '62, which one of the following cannot be true?
D: Nader joined the firm in 1964.

If J joined in '62, then K joined in '61. That settles our first two spots.

If N joined in '64, then who joined in '63? It must have been H, because H joined before N, and '63 is the only open spot that qualifies.

We don't have to worry about M at this point. M may have joined in '65 or later, it does not affect the placement of N in '64. This is why answer choice D could be true, so we can eliminate it.

I believe she says "Nader must be behind Hodges." This means Nader joined after, which is the correct order.
