A rule states, “If T is selected, then either U or V must be selected.” Which statement is the correct contrapositive? A. If U and V are selected, then T is selected B. If neither U nor V is selected, then T is not selected C. If U is not selected, then T is not selected D. If V is selected, then T must be selected Correct Answer: B. If neither U nor V is selected, then T is not selected Rationale: The original rule is T → U or V. To form the contrapositive, reverse and negate the terms and change “or” to “and”: not U and not V → not T. The absence of only U is insufficient because V could still satisfy the rule. Options A and D improperly reverse the original relationship and treat the necessary condition as sufficient. Question 2 A student has 35 minutes to complete a Logic Games section containing four games and 23 questions. Which initial pacing plan is most consistent with the recommended section-management strategy? A. Spend approximately 15 minutes on the first game and divide the remaining time equally B. Allocate approximately 8½ minutes to each game while completing easier games or questions first C. Spend exactly 1 minute on every question regardless of game complexity D. Complete the games strictly in the order presented and reserve 10 minutes for review Correct Answer: B. Allocate approximately 8½ minutes to each game while completing easier games or questions first Rationale: Dividing 35 minutes among four games provides approximately 8½ minutes per game. Prioritizing easier games or questions can secure points efficiently before time is spent on difficult material. Option A risks leaving insufficient time for later games. Option C ignores setup time and differences in difficulty. Option D assumes the presented order reflects difficulty, which is not necessarily true. Question 3 The rules state: “If A is selected, B is selected,” and “If B is selected, C is not selected.” Which deduction is valid? A. If A is selected, C is not selected B. If C is not selected, A is selected C. If A is not selected, C is selected D. If B is not selected, C is selected Correct Answer: A. If A is selected, C is not selected Rationale: The two conditionals form a valid chain: A → B and B → not C. Therefore, A → not C. The other options improperly reverse or negate the relationships. C’s nonselection does not prove A was selected, A’s absence does not require C, and B’s absence does not determine C. Conditional chains transmit consequences only in the stated direction. Question 4 A “Which of the following could be true?” question contains five answer choices. What must be true of the four incorrect choices? A. Each must be true B. Each must be false C. Each must be merely possible D. Each must be unrelated to the rules Correct Answer: B. Each must be false Rationale: The correct answer to a “could be true” question must be compatible with at least one acceptable arrangement. A statement that must be true also technically could be true. The four incorrect choices, however, cannot occur under the rules and are therefore must-be-false statements. They are not merely unlikely or unsupported; each must violate at least one rule or valid deduction. Question 5 A game describes seven musicians who must be assigned to three performance groups. Each musician must join exactly one group, and each group must contain at least two musicians. Under the SEAL framework, which element is represented by the requirement that each group contain at least two musicians? A. Situation B. Entities C. Action D. Limitations Correct Answer: D. Limitations Rationale: Limitations define the parameters that restrict how the entities may be arranged. The minimum group size and the requirement that each musician be assigned once constrain the possible distributions. The situation is the performancegroup context, the entities are the musicians, and the action is distributing them among groups. Therefore, the numerical requirement belongs to the limitations component. Question 6 A student interprets “If P is scheduled first, then Q is scheduled third” to mean that whenever Q is third, P must be first. What error has the student made? A. Mistaking a numerical restriction for a block B. Treating a necessary condition as sufficient C. Negating both terms without reversing them D. Ignoring an established entity Correct Answer: B. Treating a necessary condition as sufficient Rationale: The original statement guarantees Q’s placement when P is first, but it does not state that P is the only condition capable of placing Q third. Concluding Q third → P first is the invalid converse. The student has therefore treated the necessary result as though it were a sufficient trigger. No numerical restriction, block, or established-entity error is involved. Question 7 A question asks, “Each of the following must be true EXCEPT.” What should the test taker identify? A. The one answer that must be false B. The one answer that is not necessarily true C. The one answer that could never be false D. The one answer that appears in every acceptable arrangement Correct Answer: B. The one answer that is not necessarily true Rationale: In an EXCEPT question, the phrase before “EXCEPT” describes the four incorrect answers. Therefore, four choices must be true, while the correct answer is not required. It may be false or merely possible. Option A is too narrow because the correct answer need not be impossible. Options C and D describe statements that must be true and would therefore be incorrect. Question 8 What is the valid contrapositive of the rule “If M is assigned to Group 1, then N is assigned to Group 2”? A. If N is assigned to Group 2, then M is assigned to Group 1 B. If M is not assigned to Group 1, then N is not assigned to Group 2 C. If N is not assigned to Group 2, then M is not assigned to Group 1 D. If N is assigned to Group 1, then M is assigned to Group 2 Correct Answer: C. If N is not assigned to Group 2, then M is not assigned to Group 1 Rationale: A contrapositive is formed by reversing and negating both terms. The original rule is M1 → N2, so the contrapositive is not N2 → not M1. Option A is the converse and is not logically guaranteed. Option B negates without reversing. Option D changes the assigned groups rather than correctly negating the original conditions. Question 9 Before drawing a diagram, a student determines that a game involves placing six lectures in chronological order over six time slots. Which step of the Kaplan Logic Games Method is the student performing? A. Overview B. Sketch C. Deductions D. Questions Correct Answer: A. Overview Rationale: The Overview step identifies the game’s situation, entities, action, and limitations. Recognizing that six lectures must be sequenced chronologically establishes the nature of the task before a diagram is drawn. The Sketch step represents that task visually. Deductions combine restrictions, while the Questions step applies the completed setup to individual answer choices. Question 10 An argument establishes that employees who receive advanced training become more productive. It then concludes that every productive employee must have received advanced training. Which error has occurred? A. Mistaken reversal B. Mistaken negation C. Valid contraposition D. Quantifier de-escalation Correct Answer: A. Mistaken reversal Rationale: The evidence establishes training → productivity. The conclusion reverses this to productivity → training, which is not justified. Productive employees could have become productive for other reasons. Option B would infer no training → no productivity. Option C would infer not productive → not trained. Option D would weaken rather than reverse a claim.
