This is a Grouping: Defined-Fixed, Balanced game.
The game scenario establishes that six law students are divided into three trial teams of exactly two students each, a Defined-Fixed situation. Because each student is on exactly one of the teams, this game is also Balanced, and thus as each law student is placed, he or she can be eliminated from further placement consideration.
Although the numbering of the teams does not introduce a linear element, within each team there are different tasks: preparing an opening argument and preparing a final argument. Thus, the setup must account for these differing tasks within each group. With this consideration in mind, the initial setup appears as:
With the basic structure of the setup in place, we can consider each rule.
Rule #1. This rule establishes that M is always paired with either G or V, creating a vertical block:
However, the rule contains no specification as to which task M performs. Thus, M could prepare either the opening argument or the final argument. This could be represented either by drawing a second block that is flipped, or by using the circle notation indicating a rotating block:
Operationally, because M must always be paired with G or V, M cannot be assigned to a team with any other law student. And, because one of G or V must always be teamed with M, G and V cannot be assigned to a team together.
Rule #2. This rule specifies that L must prepare an opening argument and thus cannot prepare a final argument. The best representation for this rule is an L Side Not Law on the final argument row:
Rule #3. This rule indicates that G or R, but not both, prepare a final argument. Because at least one must prepare a final argument but both cannot, the other must prepare an opening argument. Thus, one of G and R is always preparing a final argument, and the other prepares an opening argument. This is a difficult rule to show, but one method is to use side arrows to show the variables that are in play in each row:
This representation reveals that the opening argument row is two-thirds full because L must prepare an opening argument, and the remainder of R and G must also prepare an opening argument. Thus, we can infer that if another law student prepares an opening argument, all remaining unassigned law students would have to then prepare a final argument.
This rule also links to the first rule through G, but there is no immediate inference that can be drawn from pairing the two rules.
Final Setup Thoughts: because S does not appear in any of the rules, S is a random. This leads to a final setup of:
To explore a different vein of thinking about the setup, a review of the rules reveals that the team numbers do not play a role in any of the rules, and they also do not play a role in any of the questions (except question #1, which is a basic List question where team numbers could change with no effect). Thus, the team numbers do not have a linear function in this game, and the three groups could easily be nameless. As such, one approach to creating a final setup is to disregard the numbering of the teams and simply treat the teams as equal groups. This approach allows us to then place L into one of the groups as preparing the opening statement, and the R/G dual option into another group as the opening statement. The remainder of the R/G dual option cannot be placed as a final argument as it cannot be determined which law student G or R would be paired with. These decisions allow us to reach an alternate final diagram for the game:
Note that in using this diagram you must understand that L does not have to be on team 1 (and thus answer choice (D) cannot be eliminated in question #1). Rather, L is simply occupying a space on one of the three teams, and since the numbers have no operational value, we have arbitrarily assigned L to team 1. If this concept confuses you, either eliminate the team numbers or instead use the prior final diagram.
