Section A: Grammar in Context (MCQ) [1 mark each]

---

1. (b) knows

Explanation: With "Neither... nor..." constructions, the verb agrees with the nearer subject. Here, "the teacher" (singular) is nearer than "the students" (plural), so we use the singular verb "knows." This is called proximity concord or the rule of proximity. Common mistake: Students often mistakenly make the verb agree with the first subject ("students" = plural) rather than the nearer subject.

---

2. (c) had been waiting

Explanation: "By the time" introduces a completed past time reference (the arrival of the rescue team). We need the past perfect continuous to show that an action started before another past action and continued up to that point. "Had been waiting" emphasises both the duration (three hours) and the completion before the arrival. The continuous aspect captures the ongoing nature of waiting.

---

3. (a) was

Explanation: When a singular subject is followed by "together with," "as well as," "along with," or "in addition to," the verb agrees with the main subject only, not the added phrase. The main subject is "The ancient manuscript" (singular). The intervening phrases create a parenthetical addition that does not affect subject-verb agreement.

---

4. (c) had known

Explanation: This is a Third Conditional (Type 3), used for impossible situations in the past. The structure is: If + past perfect, would have + past participle. The speaker did NOT know about the deadline in the past, so they could not submit. The condition is unreal and refers to a completed past time, making "had known" correct.

---

5. (a) shed

Explanation: "Shed" is an irregular verb with identical forms: shed (base), shed (past tense), shed (past participle). The context requires simple past tense to describe a completed action at a specific past moment ("as the credits rolled"). Common mistake: Students incorrectly add "-ed" to form "shedded," treating it as a regular verb.

---

6. (c) did she win

Explanation: "Not only" at the beginning of a clause triggers inversion (auxiliary verb before subject) in formal/written English. The pattern is: Not only + auxiliary + subject + main verb. Since the main clause uses simple past ("broke"), we use the past tense auxiliary "did" for inversion: "did she win." Common mistake: Forgetting inversion and writing "she won" OR using "had she won" which incorrectly suggests an earlier past action.

---

7. (b) be stopped

Explanation: After verbs of urging, suggesting, demanding, or recommending ("urged," "demanded," "suggested," "recommended"), we use the subjunctive mood: base form of the verb without "to" and without conjugation. The structure is: subject + urged that + object + base form. "Be stopped" is correct subjunctive form; "must stop" is grammatically possible but not the formal subjunctive required here.

---

8. (c) having revised

Explanation: "Despite" is a preposition, so it must be followed by a noun/noun phrase or gerund (-ing form). "Despite revising" is possible, but "having revised" is preferred here because the perfect gerund emphasises that the revising was completed before the feeling of anxiety. This captures the sequence: first he revised, then he still felt anxious.

---

9. (b) would not be

Explanation: In reported speech, when the original statement uses "will" for future prediction/promise, we backshift to "would" when the reporting verb is past tense ("reminded"). The original direct speech was: "Late submissions will not be accepted." In reported speech: "late submissions would not be accepted." The instructor's reminder is in the past, so future-in-the-past is required.

---

10. (b) were born and raised

Explanation: The relative clause describes a completed past state that is no longer true (they now live in Zurich). Simple past "were born and raised" is correct because we are stating facts about their past, not connecting to the present. "Have been born" is impossible (you cannot be born repeatedly). "Had been born" suggests the birth preceded another past action, which is unnecessary and overly complex here.

Section B: Grammar Transformation and Application

11. The coach demanded to know why he/she/they had abandoned his/her/their position during the final quarter of the match.

Or: The coach demanded why he/she/they had abandoned his/her/their position during the final quarter of the match.

Marking: 2 marks

• Correct reporting structure with "demanded" (0.5 mark)
• Correct backshift: "did... abandon" → "had abandoned" (0.5 mark)
• Correct pronoun shift: "you" → "he/she/they" (0.5 mark)
• Correct retention of "why" and remaining content (0.5 mark)

Teaching note: "Demand" unlike "ask" does not take "if/whether" or "asked" structure. We use "demanded to know" or "demanded why." The tense shifts back from simple past to past perfect. Pronouns must adjust from second person "you" to appropriate third person.

12. Possible answers:

• "Although the team's morale had been high until that point, the expedition was cancelled because the weather conditions had deteriorated beyond safe limits."
• "The expedition was cancelled because the weather conditions had deteriorated beyond safe limits, even though the team's morale had been high until that point."

Marking: 2 marks

• Correct subordinating conjunction showing cause/effect or concession (0.5 mark)
• All three ideas retained (0.5 mark)
• Grammatically correct sentence structure (0.5 mark)
• Logical coherence and appropriate punctuation (0.5 mark)

Teaching note: "Because," "since," "as" for cause; "although," "even though," "while" for concession. The past perfect "had deteriorated" and "had been" show sequence: morale was high first, then conditions worsened, then cancellation.

13.

Error	Correction	Error Type
(i)	"were" → "was"	Subject-verb agreement ("committee" = collective singular)
(ii)	"his" → "their" OR "her/his"	Pronoun reference (antecedent "Each expert" is singular; "their" acceptable in modern usage, or match to "her" or "his" for Dr. Rahman if gender known)
(iii)	"reach" → "reached"	Tense consistency (simple past needed in narrative context)

Marking: 3 marks (1 mark per error identified and corrected)

Teaching notes:

• Error (i): Collective nouns like "committee," "team," "group" take singular verbs when acting as a unit. British English sometimes allows plural, but Singapore PSLE standard prefers singular for formal contexts.
• Error (ii): "Each" is grammatically singular. Traditional grammar requires "his" or "her"; modern inclusive usage accepts "their" as singular they. In PSLE context, matching to known gender or rephrasing to avoid the issue is safest.
• Error (iii): The entire paragraph narrates past events; "reach" breaks tense consistency. Simple past "reached" maintains narrative coherence.

14.

Over five hundred saplings were planted along the riverbank last Saturday. The young trees have been generously donated by the community, and the new greenery will be maintained by the local council for the first two years. We hope that more bird species will be attracted by the restored habitat by next spring.

Or equivalent with grammatically appropriate passive constructions.

Marking: 3 marks (0.5 mark per correct transformation; 0.5 mark for correct retention of underlined words; 0.5 mark for overall coherence)

Teaching note: Not all verbs can or should be passivised. "Has donated" → "have been donated" (present perfect passive). "Will maintain" → "will be maintained" (future passive). "Attracts" → "will be attracted" (future passive with agent implied). "We hope" has no passive equivalent; "restored habitat" is adjectival, not passive verb. Underlined words must remain unchanged as specified.

15.

(a) had not discovered; would have been lost

(b) will have replaced OR will replace

(c) attend (subjunctive: no "-s" even for third person singular)

Marking: 3 marks (1 mark each)

Teaching notes:

(a) Third Conditional: If + past perfect → would have + past participle. The discovery happened in past; without it, loss would have resulted. Passive voice "would have been lost" is needed because treasures don't lose themselves.

(b) "By 2030" indicates future completion. Future perfect "will have replaced" emphasises completion before 2030; simple future "will replace" also acceptable if emphasising the general prediction. The future perfect is more precise for PSLE advanced level.

(c) After expressions of necessity/importance ("It is essential that," "It is vital that," "It is important that"), we use the subjunctive mood: base verb form without "to" and without "-s" for third person. Compare: "The student attends" (indicative) vs. "It is essential that the student attend" (subjunctive).

16.

Meaning 1 (She and her mother watched the dancer):
"She, together with her mother, praised the dancer that performed."

OR: "With her mother, she praised the dancer that performed."

Meaning 2 (The dancer and her mother performed together):
"She praised the dancer who, together with her mother, performed."

OR: "She praised the dancer that performed with her own mother."

Marking: 2 marks (1 mark per clear rewrite)

Teaching note: The ambiguity arises from attachment of the prepositional phrase "with her mother"—does it modify "she" (the praiser) or "the dancer" (the one performing)? Restructuring with commas, "together with," or "her own mother" disambiguates the reference.

Section C: Grammar Analysis and Application

17. The non-finite clause is "having been studying coral ecosystems for twenty years" (or reduced: "having studied coral ecosystems for twenty years" if we consider completion).

More precisely: "who had been studying coral ecosystems for twenty years" is actually a finite relative clause (contains finite verb "had been studying").

The non-finite clause in the sentence is none explicitly—or if we accept the broader reading, there is no non-finite clause in that exact sentence. However, "particularly struck by the reef's resilience" contains a past participle phrase "struck by the reef's resilience" functioning as a complement to "was."

Accepted answer: The past participle phrase "struck by the reef's resilience" functions as a subject complement (or adjectival complement) describing Dr. Rahman's state after seeing the reef.

Marking: 2 marks

• Identification of non-finite/past participle structure (1 mark)
• Correct grammatical function: subject complement/adjectival complement (1 mark)

Teaching note: Past participles after "be" often function as adjectival complements, describing the subject's state resulting from an action. "Struck" here is not part of a passive verb phrase with an agent; it's descriptive, equivalent to "was amazed/impressed."

---

18.

(a) "What made this find remarkable" functions as a nominal relative clause (or free relative clause / fused relative) acting as the subject of the sentence.

(b) "not merely... but" exemplifies a correlative conjunction (or paired conjunction / correlative coordinating conjunction).

Marking: 2 marks (1 mark each)

Teaching notes:

• (a) Unlike regular relative clauses that modify nouns, nominal relative clauses stand in for a noun phrase themselves. "What" = "the thing that." The entire clause is the subject; the predicate is "was not merely... but..."
• (b) Correlative conjunctions work in pairs to join grammatically equal elements: "not merely [noun phrase] but [noun phrase]." They require parallelism: both elements must have the same grammatical form. Here both elements are noun phrases.

---

19. The tense is past perfect continuous ("had been... lobbying") or more precisely, past perfect ("had... begun") with a gerund complement.

More accurate: "had already begun" is past perfect simple, with "lobbying" as a gerund object.

Why appropriate: The past perfect places the beginning of lobbying before the publication of the report in 2021. The narrative timeline is: [lobbying begins] —→ [report published] —→ [sanctuary established]. The past perfect is needed because a simple past "began" would suggest lobbying started after or simultaneous with publication, which contradicts "already" (indicating prior existence).

Marking: 2 marks

• Correct tense identification: past perfect (1 mark)
• Correct explanation of narrative sequence and why simple past would be ambiguous/wrong (1 mark)

---

20.

Conditional type: Third Conditional (Type 3 / Conditional III)

Second conditional rewrite:
"If we did not act now, we might lose something truly irreplaceable."

Or more naturally: "If we were not acting now, we might lose something truly irreplaceable."

Or preserving closer to original timing sense: This is challenging because second conditional refers to unreal present/future, while the original refers to past. Best acceptable rewrite: "If we did not act when we did, we might lose something truly irreplaceable" — though this blends tenses awkwardly.

Better approach acknowledging the tense challenge: The original's temporal fixedness ("when we did") makes pure second conditional difficult. An acceptable PSLE-level answer: "If we did not act then, we might lose something truly irreplaceable."

Marking: 3 marks

• Correct identification: Third Conditional (1 mark)
• Correct structure attempt at second conditional with reasonable meaning preservation (1 mark)
• Grammatical accuracy in rewrite (1 mark)

Teaching note: Third conditional → second conditional involves: had + past participle → simple past; would have + past participle → would + base verb. The temporal challenge here ("when we did" referring to past) makes this a genuinely difficult transformation. PSLE students should recognise that some meaning shifts are inevitable when changing conditional types across time references.
