#3 - Global

An interesting point to make about this game is that opportunities abound to consider, or even completely reuse, prior work. This is a huge bonus to students who don't erase earlier diagrams and who remember exactly what they've already done as they move through the questions.

Question 3 is a great example: what could allow V to be the Leader? The correct answer to question 1 has V as the leader, so should immediately be considered (and sure enough, spotting that Q and R need to be out so neither is the Leader, and that T needs to then be in accords nicely with answer choice C in the first question).

If we use question #1as a template to help answer this question, answer A is inconsistent. In question number 1 when V is a leader, smith and taylor are members, however, the correct answer to question number 3 states Neither Quinn nor smith is selected. Please explain !

Sure thing, kkorsh! Question 3 is asking for a situation where V COULD be the project leader. It's not asking for the ONLY situation where V could be that leader! In fact, there are two such situations. One of those is, as you pointed out, reflected in the correct answer to Question 1, but like Yoda once told Obi Wan, "there is another".

Let's see what happens when V is the leader:

W is out, because V and W can never be together

Q and R are out, because those two can only be in if they are the leader, and that position is full.

What's left are S, T, and X, and we need two of them to be members. What rule kicks in? Rule 2 does: S T. That means there is no way the team could consist of V, S and X.

So, our possible teams are:

V (leader), S, T (that was the answer to Q1)

V (leader), T, X (that's the other option)

In either case, if V is the leader, T has to be on the project. That eliminates answers B, C, and E, because there is no way V can be the leader if T is not selected. Answer A looks fine - V could be the leader if neither Q nor S is selected, because V, T, X satisfies that. D, however, has a problem - if neither S nor X is selected, then only V and T are selected, and we are one member short!

The short answer: This question isn't asking what MUST be true if V is the leader, but what COULD be true if V is the leader. Answer A is the only one that could be true.
