ANSWER KEY & EXPLANATIONS
1 (C) had met
- Why it is correct (The Key): The action of “meeting” happened and was completed before the moment of “realizing” in the past. We use the Past Perfect.
- Error Analysis: (A) met (Common Mistake) uses the past simple, making the two actions seem simultaneous. (B) have met (Strong Distractor) uses the present perfect, which is incorrect in a past narrative sequence. (D) had meet (Structural Error) uses the wrong past participle form.
2 (D) had forgotten
- Why it is correct (The Key): Realizing (knew – Past Simple) a state that had already occurred previously (had forgotten – Past Perfect).
- Error Analysis: (A) forgot (Common Mistake) implies the act of forgetting happened at that exact second, but the memory was already lost before he waved. (B) have forgotten (Strong Distractor). (C) had forgot (Structural Error) uses the wrong V3 form.
3 (A) had worked
- Why it is correct (The Key): The action of working together (last year) happened before the moment of recognition (“recognized”).
- Error Analysis: (B) worked (Common Mistake) lacks the clear timeline sequence. (C) were working (Strong Distractor) incorrectly uses the past continuous for a completed state. (D) had work (Structural Error).
4 (B) had
- Why it is correct (The Key): Stative/possession verbs (“have no idea”) describing a state exactly at the moment of the encounter require the Past Simple.
- Error Analysis: (A) had had (Common Mistake) overuses the Past Perfect for a state happening right then. (D) was having (Structural Error) “have” indicating possession/cognition is not used in the continuous form. (C) have (Strong Distractor) wrong tense.
5 (C) had told
- Why it is correct (The Key): “Remembered” (Past Simple). Remembering an event that occurred months before requires the Past Perfect.
- Error Analysis: (A) told (Common Mistake). (B) have told (Strong Distractor). (D) had telling (Structural Error).
6 (A) wanted
- Why it is correct (The Key): The desire to introduce him (“wanted”) occurred right in the middle of their conversation. Past Simple is required.
- Error Analysis: (B) had wanted (Common Mistake) implies the desire existed before the meeting but stopped during it, which makes no sense here. (D) was wanted (Structural Error) wrong passive form. (C) want (Strong Distractor).
7 (B) had seen
- Why it is correct (The Key): Remembering (Past Simple) an earlier event (Past Perfect).
- Error Analysis: (A) saw (Common Mistake) loses the “earlier action” nuance. (D) have seen (Strong Distractor). (C) see (Structural Error).
8 (D) had remembered
- Why it is correct (The Key): The speaker felt terrible (Past Simple) because he discovered the other person had previously memorized/retained (Past Perfect) all the details.
- Error Analysis: (A) remembered (Common Mistake). (B) has remembered (Strong Distractor). (C) had remember (Structural Error).
9 (C) hadn’t seen
- Why it is correct (The Key): The structure “since + past time marker” must be shifted back to the Past Perfect because the reference point for the entire story is in the past.
- Error Analysis: (A) didn’t see (Common Mistake). (B) haven’t seen (Strong Distractor) is a huge trap because learners are used to pairing “since” with the Present Perfect. (D) hadn’t saw (Structural Error).
10 (A) had chosen
- Why it is correct (The Key): The surprise (“seemed surprised” – Past Simple) occurred after the career choice had already been made and completed.
- Error Analysis: (B) chose (Common Mistake). (C) have chosen (Strong Distractor). (D) had choosed (Structural Error) irregular verb mistake (choose – chose – chosen).
11 (B) knew
- Why it is correct (The Key): The action of “knowing/realizing” happened instantly (“as soon as”) after the mention. Both actions are consecutive and use the Past Simple.
- Error Analysis: (A) had known (Common Mistake) misuses the Past Perfect. (D) have known (Strong Distractor). (C) know (Structural Error).
12 (D) had always thought
- Why it is correct (The Key): “Before this encounter” signals a belief that existed prior to this past event.
- Error Analysis: (A) always thought (Common Mistake). (B) have always thought (Strong Distractor). (C) had always think (Structural Error).
13 (A) had completely forgotten

- Error Analysis: (B) completely forgot (Common Mistake). (C) have completely forgotten (Strong Distractor). (D) had completely forget (Structural Error).
14 (C) hadn’t changed
- Why it is correct (The Key): The lack of change spanned from the distant past up until the moment they met.
- Error Analysis: (A) didn’t change (Common Mistake). (B) hasn’t changed (Strong Distractor). (D) hadn’t change (Structural Error).
15 (B) had known
- Why it is correct (The Key): “Pretended” (Past Simple) that the knowledge existed before and up to that point. The cognitive verb shifts back to the Past Perfect.
- Error Analysis: (A) knew (Common Mistake). (C) have known (Strong Distractor). (D) had knew (Structural Error) wrong V3 form.
16 (D) had spoken
- Why it is correct (The Key): “By the time” is a classic marker. The 10-minute conversation was completed by the time they said goodbye.
- Error Analysis: (A) spoke (Common Mistake). (C) have spoken (Strong Distractor). (B) was spoken (Structural Error) wrong passive form.
17 (A) had sent
- Why it is correct (The Key): The sending of the text (“earlier that week”) occurred before checking the phone (“checked”).
- Error Analysis: (B) sent (Common Mistake). (C) has sent (Strong Distractor). (D) had send (Structural Error).
18 (C) did I realize
- Why it is correct (The Key): Inversion with “Only after”. The main clause (“realize”) happened after he walked away, so it stays in the Past Simple (using the auxiliary “did”).
- Error Analysis: (A) I realized (Common Mistake) lacks the required inversion. (B) had I realized (Strong Distractor) misuses the Past Perfect (the realization happened after he left). (D) I had realized (Structural Error).
19 (B) had failed
- Why it is correct (The Key): The embarrassment (“was” – Past Simple) resulted from a prior failure to ask for the card before he left.
- Error Analysis: (A) failed (Common Mistake). (C) have failed (Strong Distractor). (D) had fail (Structural Error).
20 (D) had met
- Why it is correct (The Key): The wife laughed (Past Simple) because her encounter happened “the day before”—an event prior to the entire main story.
- Error Analysis: (A) met (Common Mistake). (B) has met (Strong Distractor). (C) had meet (Structural Error).
GRAMMAR POINTS TO REMEMBER
- Rule for Cognitive Verbs: In a past narrative, cognitive verbs like realize, remember, know, forget, believe are usually in the Past Simple because the mental action happens at that exact moment in the story.
- The Realized Information: The fact, detail, or event that you “realize” or “remember” usually happened long before the realization itself. Therefore, the clause following these cognitive verbs must use the Past Perfect (Had + V3).
- Classic Example: I suddenly remembered (V2) that I had forgotten (Had + V3) my keys at home.
- Immediate States vs. Deeper Past Events: Be careful not to overuse the Past Perfect. Actions, emotions, or states occurring exactly at the moment of the encounter (such as wanted, had no idea, smiled) still require the Past Simple.
- Careful with “Since” and “For”: Although “since/for” are typically taught with the Present Perfect, if you are telling a story entirely in a past context, you must shift them back to the Past Perfect. (See Q9 and Q14).
