Shouldn't the 3rd condition( "the site visit that include Quinn must take place before any site visit that either Rodriguez or Taylor" ) be : Q - -R or Q - -T or Q - -R&T due to "either R or T??" I'm totally lost here.

Rule #3 merely explains that Q is going to be before any site that either R or T visit (the either/or is because R and T could be on two different sites or the same site).

So, Q > R, T

This is a diagramming rule, not a Sufficient & Necessary rule. The point of the rule is to give us the location of one variable relative to the location(s) of two other variables.

This tells us that R and T cannot be visited on the first day because Q's visit must take place before the visit that includes either R or T (again either/or is in this language because R and T could be on the same day or on two different days).

Hope that clears things up! Please let us know if you have any other questions.
