7. Ambiguous → A (Open to more than one interpretation or vague) Root: Latin ambigere (to wander)
Rationale: The outcome—"allowing both nations to claim victory while delaying definitive demarcation"—proves the text lacked singular, explicit clarity.

8. Scrutinize → C (Examine or inspect thoroughly and critically) Context: Aerospace Engineering
Rationale: Checking "every square millimeter" before safety certification indicates rigorous, exhaustive examination rather than superficial checking (Distractor A).
9. Viable → A (Capable of working successfully or feasible) Domain: Economics / Project Planning
Rationale: The conditional phrase "without municipal tax subsidies or private venture backing" denotes financial feasibility and operational survivability.
10. Explicit → B (Stated clearly and in direct, precise detail) Antonym: Implicit
Rationale: Providing "exact evacuation routes, eye-wash durations, and storage procedures" exemplifies unambiguous, fully articulated guidance.
Part 2: Multiple-Meaning Words Semantic Breakdown (Q11–Q15) Target: Polysemy & Shifted Denotations
11. Sanction → B (A threatened penalty for disobeying a rule or law) Contronym Alert
Contextual Shift: Sanction is an auto-antonym. While Option A ("official approval") is valid in phrases like "sanctioned school events," the phrase "punitive trade... on petroleum exports" locks the coercive penalty meaning.
12. Harbor → B (To hold a persistent thought or feeling inwardly) Noun vs. Verb Metaphor
Contextual Shift: While sophomores know "harbor" as a boat basin (Option A) or sheltered haven (Option C), here it functions psychologically: giving internal dwelling to "deep doubts."
13. Qualify → C (Modify, limit, or narrow the scope of a claim) Rhetorical Function
Contextual Shift: In argumentation, qualifying a claim means bounding its certainty (e.g. "limiting to urban schools"), contrasting sharply with colloquial qualification (earning entry/passing standards, Option A).
14. Articulate → C (To express an idea clearly and coherently in speech) Anatomical vs. Rhetorical
Contextual Shift: In biology, articulated limbs possess joints (Option A). In courtroom rhetoric, the attorney's ability to express an alibi with clarity dictates definition C.
15. Temper → C (To moderate or soften by adding a counterbalancing element) Metallurgy & Psychology Traps
Contextual Shift: Students routinely confuse this verb with losing one's temper (anger, Option A) or tempering steel (Option B). In financial analysis, tempering optimism means restraining it with caution.

16. Champion → B (Vigorously advocate for or defend a cause) Noun vs. Transitive Verb
Contextual Shift: Shift from concrete noun (trophy winner, Option A) to legislative action verb: spearheading and advocating for early childhood education policies.
17. Novel → A (Strikingly new, original, or unprecedented) Etymology: Latin novus (new)
Contextual Shift: Students often conflate the noun (literary narrative, Option B) with the academic adjective modifying a scientific patent or breakthrough methodology.
18. Commission → B (Formally authorize or order the production of something) Administrative Context
Contextual Shift: Differentiates the governmental delegation of investigative duties to a panel from sales agent commissions (Option A) or military appointments (Option C).
19. Reserve → C (Restraint in expressing emotions, thoughts, or opinions) Behavioral/Character Trait
Contextual Shift: Contrast with environmental preserves (Option A), resource caches (Option B), or table bookings (Option D). Here it captures emotional self-control under pressure.
20. Disposition → A (The final settlement, resolution, or distribution of a matter) Legal/Formal Register
Contextual Shift: Sophomores frequently default to mood/temperament (Option B). In judicial settings, "disposition" refers to the formal legal resolution of an estate or lawsuit.
Focus on Context Clue Typologies (contrast signposts like rather than, syntactic appositives, and cause-effect chains). Have students practice generating sentences using morphemic roots (e.g., sub-, syn-).
Introduce the Syntax Swap Technique: check whether the target word acts as noun, verb, or adjective in the sentence. Model explicit distinction between conversational registers and discipline-specific academic registers.
