ANSWER KEY & EXPLANATIONS
1 (A) had already escaped
- Why it is correct (The Key): “By the time” introduces the later past action (police arriving). The thieves escaping happened completely before the police arrived, requiring the Past Perfect.
- Error Analysis: (B) already escaped (Common Mistake) uses Past Simple, losing the exact sequence of events. (C) have already escaped (Strong Distractor) uses Present Perfect, which is incorrect in a past narrative. (D) had already escape (Structural Error) lacks the ‘d’ for the past participle.
2 (D) had parked
- Why it is correct (The Key): “After + Past Perfect” shows that the parking was completed before the speaker “noticed” (Past Simple) the broken window.
- Error Analysis: (B) parked (Common Mistake). (A) have parked (Strong Distractor). (C) had parking (Structural Error).
3 (A) had heard
- Why it is correct (The Key): The speaker “called” (Past Simple) as a reaction to a sound they experienced just before making the call.
- Error Analysis: (B) heard (Common Mistake). (C) have heard (Strong Distractor). (D) had heared (Structural Error) incorrect irregular verb form (hear -> heard).
4 (B) had stolen
- Why it is correct (The Key): “Before + Past Simple” (started ringing) means the action in the main clause happened first. The TV was gone before the alarm went off.
- Error Analysis: (A) stole (Common Mistake). (D) have stolen (Strong Distractor). (C) had stealed (Structural Error) incorrect V3 form (steal -> stole -> stolen).

6 (B) had put on

8 (C) had happened

- Error Analysis: (B) jumped (Common Mistake). (C) have jumped (Strong Distractor). (D) had jump (Structural Error).
11 (C) had seen
- Why it is correct (The Key): The recognition (Past Simple) was possible due to a completed action “earlier that afternoon” (Past Perfect).

- Error Analysis: (A) emptied (Common Mistake). (C) have emptied (Strong Distractor). (B) had empty (Structural Error).
15 (B) did I step
- Why it is correct (The Key): Inversion triggered by “Only after + Past Perfect”. The action of stepping out happened after the police secured the area, so it takes the Past Simple inverted form (did + S + Base Verb).
- Error Analysis: (A) I stepped (Common Mistake) lacks the necessary grammatical inversion. (D) had I stepped (Strong Distractor) uses the wrong tense; the stepping out happened second, not first. (C) I had stepped (Structural Error).

- Error Analysis: (A) left (Common Mistake). (D) have left (Strong Distractor). (B) had leaved (Structural Error) incorrect conjugation.
17 (A) had cut

- Error Analysis: (B) cut (Common Mistake). (C) have cut (Strong Distractor). (D) had cutted (Structural Error) ‘cut’ remains ‘cut’ in V3
18 (C) had taken
- Why it is correct (The Key): “By the time” the detectives entered (Past Simple), the stealing was already fully accomplished (Past Perfect).
- Error Analysis: (A) took (Common Mistake). (D) have taken (Strong Distractor). (B) had took (Structural Error) wrong V3 form.
19 (D) had checked
- Why it is correct (The Key): “Not until” creates an inversion in the main clause (“did I finally feel”). The action that occurred first (the canine unit checking) takes the Past Perfect.
- Error Analysis: (A) checked (Common Mistake). (C) have checked (Strong Distractor). (B) had check (Structural Error).
20 (A) had searched
- Why it is correct (The Key): The house “looked” (Past Simple) like a disaster because the criminals had completed their search before the police arrived.
- Error Analysis: (B) searched (Common Mistake). (D) have searched (Strong Distractor). (C) had search (Structural Error).
GRAMMAR POINTS TO REMEMBER
- Reporting Crimes and Sequences: In police reports or news, the Past Perfect (had + V3) is strictly used to describe what the criminals had already done before the authorities or witnesses arrived (Past Simple).
- Example: When the police arrived (V2), the suspect had fled (had + V3).
- The “By the time” Formula: This is heavily tested at the B1 level.
- By the time + Past Simple (the later event) -> Main clause is Past Perfect (the earlier event).
- Realizations in the Past: When a witness says “I realized”, “I noticed”, or “I remembered” (Past Simple), the fact they are remembering usually happened before that moment, requiring the Past Perfect.
- Example: I noticed that someone had broken the window.
- Advanced Emphasis with Inversions: To make a testimony sound highly formal and dramatic, English speakers use inverted structures for the later action (Past Simple):
- Only after + [Past Perfect Clause] + did + Subject + Base Verb.
- Not until + [Past Perfect Clause] + did + Subject + Base Verb.
