Hi, this is in reference to the question dealing with the trains arriving from the linear games lesson video. On question 17, it seems that both A and E "Could be true". I put the trains arriving in the following order: RTQWVSY and chose answer A because looks like S could arrive sixth. Answer choice E has R arriving 1st, which could also be true. Where did I go wrong?

    Pay close attention to the restriction that question 17 places: "EXACTLY ONE of the trains arrives after the Wooster but before the York." As you can see in the video explanation, that means "W_Y." But, in your series: "RTQWVSY," you have two trains between "W" and "Y." Hope that clears things up! Please let us know if you have any other questions.

    Don't I feel dumb. Thanks. I see it clearly now
