82 Game 2
Comments

I have a question on Q10.
I could not choose any answers, including answer E, Saturday is Q.
One of the rules says that Q is the day before G, which means that Q will not be able to occupy Saturday because it has to be followed by G.
what is wrong with me?

You forgot Rule 2!
The following is one example of an acceptable ordering:
M T W R F S
Q G L P N Q

I am sorry I still have a hard time seeing how Q can be last if it says Q before G. I thought the only ones that can repeat are L and P since G can't repeat and If G can't repeat neither can Q since we have to have QG. Are we to take this rule that as long as we have one instance of QG that's all we need? If so, how do we determine that?

With Rule 4 here, as with every rule, always, you will be correct to do a precise and literal reading of the rule. If the test writers had intended for every instance of Q to be followed by G, they would have written just that! As it is, following the rule exactly as written allows for the example I gave above.
Try it this way: ask yourself whether Q is on the day before G (it is). Thus, Rule 4 is satisfied!
Clearer?
