Section A: Multiple Choice (Questions 1–5)

---

Q1. Answer: (2) ancient [1 mark]

Explanation: "Antiquated" means very old or out of date, typically because of age rather than use. The context clue "from the 1800s" confirms we need a word related to great age. "Ancient" is the closest match. "Modern" is the opposite meaning. "Broken" and "expensive" are not related to the core meaning of age.

Teaching note: The root "antiq-" connects to "antique" — both refer to old objects. Recognising word roots helps unlock meaning.

---

Q2. Answer: (3) general agreement [1 mark]

Explanation: "Consensus" means a general agreement among a group of people. The context "finally reached" after "hours of discussion" suggests people came together in agreement. "Disagreement" and "argument" are opposites. "Confusion" does not fit the positive resolution described.

Teaching note: Consensus requires unanimous or near-unanimous agreement, not just a majority vote. It implies collective acceptance.

---

Q3. Answer: (2) confused [1 mark]

Explanation: "Perplexed" means completely puzzled or confused by something complicated. The context "unusual clues" explains why the detective felt this way — the clues did not make sense. "Entertained," "frightened," and "satisfied" do not match the mental struggle implied.

Teaching note: "Per-" as an intensifier + "plex" (from Latin for "entangle") = thoroughly entangled in thought. Related words: perplexing, perplexity.

---

Q4. Answer: (2) original and creative [1 mark]

Explanation: "Innovative" means introducing new ideas or methods; original and creative in thinking. The context "combined flavours no one had ever tasted together" demonstrates novelty and creativity. "Traditional" is the opposite. "Simple" and "expensive" do not capture the core meaning of newness.

Teaching note: From Latin "innovare" (to renew). Note the spelling: innovative, not innovative (no extra 'n').

---

Q5. Answer: (1) deep respect [1 mark]

Explanation: "Reverence" means deep respect for someone or something, often with a sense of awe. The context "solemn ceremony at the war memorial" creates a serious, respectful atmosphere. "Boredom," "excitement," and "curiosity" do not match the gravity of the occasion.

Teaching note: Reverence often applies to sacred or solemn contexts. Related word: revere (verb form).

---

Section B: Context Clues (Questions 6–10)

---

Q6. Answer: very tired / exhausted / worn out [1 mark]

Explanation: The context provides multiple clues: "six hours without rest," "legs trembled," and "barely keep their eyes open" all describe extreme physical tiredness. "Fatigued" means extreme tiredness resulting from mental or physical exertion.

Marking note: Accept "very tired," "exhausted," "extremely weary," or equivalent phrases. Must convey the intensity beyond ordinary tiredness.

Teaching note: "Fatigue" is more formal than "tired." It often appears in medical, military, or formal contexts. Notice the "-ed" ending making it an adjective describing the hikers' state.

---

Q7. Answer: not discouraged / not intimidated / brave despite difficulties / determined [1 mark]

Explanation: The context shows contrast: "Despite the heavy rain" would normally discourage people, but the runners continued with "determined smiles." "Undaunted" means not discouraged by difficulty or danger. The actions "pulled up their hoods," "tightened their shoelaces," and "continued running" demonstrate courage and persistence.

Marking note: Accept "not discouraged," "not put off," "brave," "fearless in the face of difficulty," or equivalent. Must include the idea of continuing despite challenge.

Teaching note: Break into parts: "un-" (not) + "daunted" (discouraged or intimidated). Daunt appears as "daunting" (intimidating). Double negative structure: "undaunted" = not not-courageous.

---

Q8. Answer: become damaged or decayed over time through neglect / no longer maintained / in bad condition due to lack of repair [1 mark]

Explanation: The detailed description provides clear evidence: "crumbling walls," "moss," "collapsed roof beams," "cracked stone floors," and "wild vines." These all result from long-term neglect. "Fallen into disrepair" is an idiom meaning to become damaged because no one has repaired or maintained something.

Marking note: Must mention neglect/lack of maintenance AND deterioration. "Old" alone is insufficient — the phrase emphasises cause (neglect) not just effect (age).

Teaching note: This is a common exam idiom. "Disrepair" = state of being broken/worn out. Preposition is always "into": fall INTO disrepair (not "to" or "in").

---

Q9. Answer: unnecessarily complicated and difficult to follow / overly complex and confusing / twisted and unclear [1 mark]

Explanation: The context explicitly states the effect: "even her teacher struggled to follow," "jumped from one unrelated idea to another," "contradictory examples," and "never reached a clear conclusion." "Convoluted" means extremely complex and difficult to follow.

Marking note: Must include both complexity AND confusion/difficulty. "Long" or "boring" are insufficient.

Teaching note: From Latin "convolvere" (to roll together). Think of a convoluted path — winding back on itself, hard to trace. Related to "convolution" (a twist or fold).

---

Q10. Answer: extremely serious or severe / terrible / urgent and dreadful [1 mark]

Explanation: The examples establish extreme severity: "no clean running water," "barefoot even in winter," "one small meal each day." "Dire" means extremely serious or urgent — often used for emergencies, suffering, or terrible situations.

Marking note: Must convey extremity/severity, not just "bad." "Very bad" acceptable; "poor" alone insufficient.

Teaching note: "Dire" intensifies whatever noun it modifies. Other collocations: dire consequences, dire warning, dire straits. From Latin "dirus" (fearful, ominous).

---

Section C: Word Forms and Usage (Questions 11–15)

---

Q11. Answer: (2) construction [1 mark]

Explanation: The sentence needs a noun to follow "The" and precede "of." The structure is [definite article] + [noun] + [prepositional phrase]. "Construction" (noun meaning the process of building) fits grammatically and semantically.

• construct = verb (to build) or noun (concept, rarely used for building)
• constructive = adjective (helpful, positive)
• constructed = past tense verb or past participle

Teaching note: Word family: construct (v.) → construction (n.) → constructive (adj.) → constructively (adv.). Note stress shifts: conSTRUCT (v.) vs CONstruction (n.).

---

Q12. Answer: (3) disastrous [1 mark]

Explanation: The sentence needs an adjective to describe "decision" and follows the linking verb "was." "Disastrous" means causing great damage or suffering; catastrophically bad. The context "caused more problems than it solved" confirms this meaning.

• disaster = noun (catastrophe)
• disastrously = adverb (modifies verbs/adjectives)
• disasterous = incorrect spelling (common error)

Teaching note: "Disaster" + "-ous" = disastrous. The "e" drops before the suffix. This follows the rule: drop silent "e" before "-ous" (compare: fame → famous, continue → continuous).

---

Q13. Answer: (3) considerably [1 mark]

Explanation: The sentence needs an adverb to modify the adjective "impressed." "Considerably" means to a large extent; significantly. It intensifies how impressed the teacher was.

• considerable = adjective (large in amount/extent)
• consider = verb (to think about)
• considerably = adverb (modifies adjectives/verbs/adverbs)
• considering = present participle or preposition

Teaching note: Adverb formation: adjective + "-ly." "Considerable" → "considerably." The "-ly" suffix converts the adjective to an adverb that can modify "impressed."

---

Q14. Answer: (2) remorse [1 mark]

Explanation: The sentence needs a noun after the preposition "with" and before the prepositional phrase "for his careless actions." "Remorse" (noun = deep regret for wrongdoing) fits the grammatical slot.

• remorseful = adjective (feeling remorse)
• remorsely = non-standard/incorrect form
• remorseless = adjective (without remorse; cruel)

Teaching note: Common pattern: fill with [emotion noun]. The driver was filled with remorse, not the adjective form. "Remorse" comes from Latin "remordere" (to bite back — conscience bites back at you).

---

Q15. Answer: (2) revolutionary [1 mark]

Explanation: The sentence needs an adjective to modify "discovery." "Revolutionary" means involving or causing a complete change; radically new or innovative. The context "changed our understanding" confirms this transformative quality.

• revolution = noun (dramatic change; circular movement)
• revolutionise = verb (to change completely)
• revolutionised = past tense/past participle

Teaching note: "-ary" adjective suffix converts noun to descriptive word. Note spelling: one "l" in British English (revolutionary), though "revolutionize" with "z" in American English. Singapore follows British spelling: "revolutionary."

---

Section D: Vocabulary in Action (Questions 16–20)

---

Q16. Answer: (C) reiterated [1 mark]

Explanation: The context demands a verb meaning to repeat or say again, especially for clarity. "Your earlier explanation was too vague" implies the directions need repetition with more clarity. "Reiterated" means said or done again for emphasis or clarity.

• "Please reiterated" → grammatically correct as imperative: [You] reiterated the directions.

Teaching note: From Latin "re-" (again) + "iterare" (to repeat). Often confused with "repeated" — reiteration specifically implies restatement with emphasis or for clarity, not just mechanical repetition.

---

Q17. Answer: (B) meticulous [1 mark]

Explanation: The context "ensuring no detail was overlooked" defines meticulousness — showing great attention to detail; very careful and precise. A meticulous person is thorough and exact.

Teaching note: From Latin "meticulosus" (fearful, timid) → shifted to "overly careful about details." Medically, meticulous wound care prevents infection. The "-ulous" suffix also appears in: fabulous, ridiculous, miraculous.

---

Q18. Answer: (E) exacerbate [1 mark]

Explanation: The sentence structure needs a verb following "will." The context "Throwing plastic into the ocean" worsens an existing problem. "Exacerbate" means to make a problem worse or more severe.

Teaching note: From Latin "exacerbare" (to irritate, provoke). Not "exasperate" (to irritate a person). Common confusion: exacerbate = worsen (situation); exasperate = annoy (person). Memory aid: "exacerbate" contains "acerb" (sharp, bitter, like acerbic).

---

Q19. Answer: (D) ambiguous [1 mark]

Explanation: The context explains the effect: "allowing both parties to interpret it differently." "Ambiguous" means open to more than one interpretation; having a double meaning. This deliberate vagueness serves a specific purpose in contracts.

Teaching note: From Latin "ambiguus" (wavering) from "ambigere" (to wander, go around). "Ambi-" prefix = both ways (like ambidextrous, ambivalent). Distinguished from "ambivalent" = mixed feelings; "ambiguous" = unclear meaning.

---

Q20. Answer: (A) indispensable [1 mark]

Explanation: The sentence structure needs an adjective after "is" to complement the subject. "Indispensable" means absolutely necessary; too important to be without. A reliable dictionary is essential for improving writing — you cannot do without it.

Teaching note: From "in-" (not) + "dispensable" (able to be done without). Double negative structure: in-dis-pens-able = not able to be dispensed with. Related to "dispense" (distribute, administer) and "dispensary." Opposite: dispensable (expendable, unnecessary).
