LSAT Logic Games: Grouping and Selection Games 3

Question 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?

Accepted Answer

K, L, M are hired

Answer

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

Question 2

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

Accepted Answer

A maximum constraint on Group A

Answer

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

Question 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?

Accepted Answer

C is in Group 2 and B is in Group 1

Answer

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.

Question 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?

Accepted Answer

Groups with Y must also include Z and exclude X

Answer

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

Question 5

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

Accepted Answer

An element with no rules governing its placement

Answer

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