  1. A hiring committee must select exactly 3 employees from applicants J, K, L, M, N. The rule states K and L cannot both be hired. Which scenario is impossible?

    Answer: K, L, M are hired

    K and L cannot both be hired, so any group containing both violates the constraint.

  2. In a defined grouping game, the rule 'No more than 2 members of Group A can be selected' functions primarily as:

    Answer: A maximum constraint on Group A

    The phrase 'no more than 2' sets an upper limit (maximum) on the size of Group A.

  3. Six items—A, B, C, D, E, F—are split into Group 1 (3 items) and Group 2 (3 items). Rule: If A is in Group 1, then C is in Group 2. Rule: If D is in Group 2, then B is in Group 1. If A and D are both in Group 1, which must be true?

    Answer: C is in Group 2 and B is in Group 1

    A in Group 1 forces C to Group 2; D in Group 1 means D is NOT in Group 2, so the second rule does not fire—but B's placement from the second rule requires D in Group 2 to trigger, which doesn't occur; however C must be in Group 2 from rule 1.

  4. A selection game has 7 candidates and requires exactly 4 to be chosen. The rule states: 'If X is chosen, Y is not chosen, and if Y is chosen, Z is chosen.' How many acceptable groups include Y?

    Answer: Groups with Y must also include Z and exclude X

    Y chosen triggers Z chosen (Y→Z) and precludes X (contrapositive of X→not Y means Y→not X).

  5. In LSAT grouping games, a 'floater' element is best described as:

    Answer: An element with no rules governing its placement

    A floater has no specific rules attached to it, so it can be placed freely wherever slots allow.

  6. Seven students—P, Q, R, S, T, U, V—are assigned to clubs 1 and 2. Club 1 has exactly 4 members; Club 2 has exactly 3. If P and Q must be in the same club and R and S must be in different clubs, what is the maximum number of students whose placement is fully determined by placing P in Club 1?

    Answer: 2

    Placing P in Club 1 forces Q to Club 1 as well, determining exactly 2 placements directly.

  7. A game requires selecting 3 from {A, B, C, D, E}. The constraint is: 'Exactly one of B or C must be selected.' If B is not selected, which is true?

    Answer: C must be selected

    The 'exactly one' constraint means if B is out, C must be in to satisfy the requirement.
