Hello @SorooshKosha,Good point, you could also infer that at least one of P/T has to be included, or the same inference about any set of two variables except U/V. So you understand why one of I/P has to be included, but you are asking why she focused on that particular deduction in the setup.
I believe she wrote that deduction down because it has a big effect on the setup. It reserves one of the non-mauve spaces for I/P. This becomes quite helpful on questions like #14 or #17. We are easily able to eliminate answers that fill both of those non-mauve spaces without including either I or P, as we know that these variables cannot go anywhere else.
P/T is not as helpful, because T does not have a color restriction. But, this inference ends up being very important on question #13 when the tyrannosaur is removed.
I don't blame you, I also didn't see that I/P inference at first, but I figured it out at some point while answering questions. I should have spent a minute longer making inferences. Something else I began to pay attention to was which dinosaurs were able to be mauve. With P, I, and S eliminated, I know I had to choose two of U/V, T, and L. This was helpful as well.
