Question Type: Conditional
Tough question! This question gives us multiple pieces of extra, conditional ("If") information that will apply to this question only: G is shown three times, H twice, and L once. Given these conditions, we’re looking for the answer that "must be true" in all cases.
The first thing we want to do is use our diagram and the additional information to create inferences.
First, if G is shown on all three days, then H can’t be shown on Saturday (remember, either G or H, but not both, is shown on Saturday).
Next, if H is shown twice, and if H is NOT shown on Saturday, then H must be shown on Thursday and Friday. Remember that G is shown on all three days, so Friday must have H first and G second.
If we do a good job of following the inference chain, we’ll often be led directly to the correct answer. Knowing that H and G are both shown on Friday seems like a big inference. Let’s check the answers to see if one matches. Sure enough, (E)’s the one. On conditional questions, follow the inference chain before you start a trial and error approach! You’ll most definitely save yourself a lot of time.
