December 2015 LSAT Logic Game 3 Setup
In this video, we’re going to review everyone’s favorite game from the December 2015 LSAT, the third logic game, which states:
“Four employees: Jackson, Larrabee, Paulson, and Torillo—are to select from among four offices—W, X, Y, and Z. The order in which they select, from first to fourth, is to be decided by a random drawing. Each employee has ranked the offices from first (highest) to fourth (lowest) as follows:”
And then it sets forth the rankings for the employees and then it proceeds to the restrictions.
Before we move to the restrictions, let’s take a closer look at what we’re seeing here. Notice, we have four employees, Jackson, Larrabee, Paulson and Torillo. They’re selecting among four offices, W, X, Y and Z. They’re going to select in order first to fourth. We do have an order here. We will be selecting first, second, third, fourth. The priority will be determined by a random drawing but it’s really a multi-linear game, because not only are we going to select an office, we’re going to need to know which employee made that selection. We’re going to see employee and offices.
Just to make sure we keep it clear, I’m going to draw out the rankings of each employee. Again, we have our four employees. There you have what is set forth there in terms of ranking priority for each employee. Before we proceed here, I just want to make a couple of comments. The first and most important thing at this point, a lot of students had already freaked out. This game is not your traditional game. It seems as you see, as we proceed here to the restrictions, they’re very abstract but freaking out is not going to do anything for you on the exam. It’s really important to remain calm, make sure you have a clear understanding of the conditions and go through the questions as quickly as possible, applying the conditions that you’re given.
Keeping that in mind, let’s turn our attention to the restrictions. The first restriction here tells us each employee selects an office that has not been selected previously. What that tells us is that each office is going to appear once, and only once so this is a one-to-one game. Now, again, that had to be stated. We couldn’t assume that each employee was going to get their own office. It was possible that they could share. That rule sets forth that each office is going to be selected by one employee.
The next rule tells us that each employee selects only one office. That establishes that our employees now are also going to be one-to-one. We have four employees, four offices.
And the last rule states that each employee selects the office that he or she ranks the highest among the unselected offices. Obviously, that makes plenty of sense. That’s the whole idea of a ranking priority.
Now, let’s just, for purposes of really making sure we understand this game before proceeding, let’s do some examples of how this game might play out. Turning our attention over here to our possibilities. The first thing I want you to notice is that every single employee has either X or Y as their first priority. Clearly, these are the corner offices. That allows us to make a deduction here that the first office selected is going to be either X or Y.
Turning our attention now to the second position, we notice that W does not appear. When you combine that with the fact that W also doesn’t appear in anyone’s first position that allows us to conclude that W does not appear second. So that means that now, W must appear either third or fourth. Let’s place W third just to try it out and get a better sense of how this game is actually going to work here.
