    Summary: The 3-Step Elimination Checklist

    Use this exact protocol for every Science, Environment, and Biotechnology Odd Sentence Out question.

    • 1

      Define the Anchor

      Read all five sentences. Draft the central theme in five to seven words.

      • Check: What is the single unifying subject?
    • 2

      Identify the Flow

      Determine the structure: Chronological Process, Problem-Solution, or Claim-Evidence.

      • Check: How are the sentences logically glued together?
    • 3

      Execute Elimination

      Evaluate each sentence against the Anchor and the Flow.

      • Check: Does this sentence advance the specific argument, or just share the same jargon?

    Summary: Thematic Signposts and Red Flags

    Quick reference for identifying the core structure and spotting the intruder.

    Science Passages Signposts: Hypothesis, mechanism, data, observation, implication. Red Flag: Introduces a parallel scientific field or jumps to a conclusion before the mechanism is explained.
    Environment Passages Signposts: Threat, driver, consequence, ecosystem impact, mitigation, policy. Red Flag: Focuses purely on tangential economic benefits, or introduces a historical detour that does not inform the current crisis.
    Biotechnology Passages Signposts: Innovation, biological process, practical application, ethical friction, regulatory hurdle. Red Flag: Gets stuck in deep molecular weeds (ignoring the application or ethics), or introduces a social issue without linking it to the biological innovation.

    • 1

      Define the Anchor

      Read all five sentences. Draft the central sociological theme in five to seven words.

      • What is the specific argument about this human system?
    • 2

      Identify the Arc

      Determine the structure: Systemic Critique, Evolutionary Shift, or Problem-Solution.

      • How are the sentences logically building this specific narrative?
    • 3

      Execute Elimination

      Evaluate each sentence against the Anchor and the Arc.

      • Does this sentence actively build the author's specific argument, or is it just a true fact in the same neighborhood?

    Academic & Research
    • Phenomenon
    • Mechanism of flaw
    • Consequence
    • Regulatory response
    Introduces an unrelated institutional fact (e.g., founding dates) or shifts to a different academic field without a bridge.
    Workplace & Hiring
    • Traditional norm
    • Catalyst for shift
    • New paradigm
    • Rationale or outcome
    Abruptly reverts to the old norm without a contrasting transition, or zooms in on a hyper-specific, irrelevant corporate anecdote.
    Societal Dynamics
    • General claim
    • Specific example
    • Broader consequence
    • Contrasting principle
    The "Plausible but Peripheral" statement—a factually true detail that does not advance the specific argument being built.

    Odd Sentence Out: Solved Questions with Step-by-Step Explanations (2 Problems)

    Question 1 · Verbal Ability and Reading Comprehension NAT
    Five jumbled up sentences (labelled 1, 2, 3, 4 and 5), related to a topic, are given below. Four of them can be put together to form a coherent paragraph. Identify the odd sentence and key in the number of that sentence as your answer.
    1. The concept of "moral luck," introduced by Thomas Nagel, challenges the intuition that moral responsibility should depend only on factors within an agent's control.
    2. For instance, two drivers may behave identically recklessly, yet only one strikes a pedestrian who happens to cross the street at that moment, creating vastly different moral assessments.
    3. This asymmetry suggests that our ethical judgments are far more contingent on external circumstances than most philosophical frameworks acknowledge.
    4. Empirical studies in developmental psychology confirm that children as young as four begin to distinguish between intentional harm and accidental outcomes when evaluating peer behavior.
    5. Consequently, any comprehensive theory of moral responsibility must account for the uncomfortable reality that chance plays an irreducible role in determining blame.
    Correct Answer:

    4

    Step-by-Step Solution

    Key idea: This is an empirical_vs_moral trap question, recognisable because four sentences construct a tight philosophical argument about moral luck and its implications for ethical theory, while one sentence pivots to citing empirical developmental psychology data that shifts the domain from normative philosophy to descriptive science.

    Step 1: Identify the core theme. The paragraph builds a philosophical argument about moral luck. Sentence 1 introduces Nagel's concept. Sentence 2 provides the classic thought experiment (two reckless drivers). Sentence 3 draws the philosophical implication (contingency of ethical judgment). Sentence 5 concludes with the theoretical demand (any theory must account for chance).

    Step 2: Analyze the outlier. Sentence 4 cites empirical developmental psychology studies about children's moral reasoning. While topically adjacent to "morality," it shifts the paragraph from a normative philosophical argument to a descriptive scientific finding. The paragraph argues about what moral theory should accommodate; sentence 4 reports what children actually do, which is a fundamentally different mode of discourse.

    Step 3: Verify the chain. 1 (Philosophical concept) → 2 (Thought experiment) → 3 (Implication) → 5 (Theoretical conclusion). Sentence 4 breaks the normative chain with empirical data.

    Answer: 4

    Question 2 · Verbal Ability and Reading Comprehension MCQ

    According to the Final Exam Checklist, under what condition can a scientifically accurate sentence still be correctly identified as the odd one out?

    1. A.

      If it breaks the specific argumentative thread of the paragraph

    2. B.

      If it is the longest sentence in the paragraph

    3. C.

      If it uses passive voice

    4. D.

      If it contains a statistical figure

    Correct Answer:

    A

    Step-by-Step Solution

    Key idea: This tests a specific, counterintuitive rule from the final exam checklist.

    Step 1: Recall the checklist's final point regarding scientifically true statements.

    Step 2: Understand that coherence is about the argumentative thread, not just factual accuracy.

    Step 3: Conclude that a scientifically true sentence can still be the odd one out if it breaks the specific moral or logical argument being built.

    Answer: A
