O in First Scenario

Started by lsatstudier1 · started 2020-08-03 16:31 · last activity 2020-08-04 14:08 · 1 reply

In the video explanation, the solver left O as a potential option for spot 6. Can't we eliminate O as a possibility for spot 6 since there is already an O in spot 4 and there is only one O specified in the local rules for this question? I'm just wondering if there is a particular reason or advantage to why O was left as an option for spot 6

    @lsatstudier1, happy to help! Yes, that is a valid and helpful deduction. Great job! Since this particular question specifies there is only one O and we have already placed it in spot 4 in the first scenario, we can replace the binary option of O/G in spot 6 with G. There is no particular reason/advantage to leaving O as an option for spot 6. It was probably done so in the video out of concern for consistency with the diagram from our original set-up in an attempt to clarify the explanation. Does that make sense? Please let us know if you have any other questions.
