ANSWER KEY & EXPLANATIONS
1 (C) missed
- Why it is correct (The Key): The action of missing the meeting is the main past event being reported. It happened at a specific time in the past (“this morning”), requiring the Past Simple.
- Error Analysis: (A) had missed (Common Mistake) incorrectly shifts the main action further back into the past without a clear reference point. (B) have missed (Strong Distractor) uses the Present Perfect, which contradicts the finished time “this morning”. (D) was missed (Structural Error) uses passive voice incorrectly.
2 (B) had broken
- Why it is correct (The Key): The router breaking happened before the consequence of not being able to join (Past Simple). The Past Perfect is needed to show this cause-and-effect timeline.
- Error Analysis: (A) broke (Common Mistake) makes the two events seem simultaneous. (C) has broken (Strong Distractor) mixes present perfect into a past narrative. (D) had break (Structural Error) uses the wrong verb form (needs V3: broken).
3 (D) had ended
- Why it is correct (The Key): The word “already” strongly indicates that the meeting’s end occurred prior to the action of opening the app (Past Simple).
- Error Analysis: (A) ended (Common Mistake). (C) has ended (Strong Distractor). (B) had end (Structural Error).
4 (A) had put
- Why it is correct (The Key): The reason for not hearing the notification (Past Simple) is an action that took place even earlier (“the night before”).
- Error Analysis: (B) put (Common Mistake). (C) have put (Strong Distractor). (D) had putted (Structural Error) ‘put’ is an irregular verb; its V3 form is still ‘put’.
5 (D) had left
- Why it is correct (The Key): By the time the employee logged in at 9:30 AM (Past Simple), the action of the colleagues leaving was already complete.
- Error Analysis: (A) left (Common Mistake) lacks the sequence emphasis. (B) has left (Strong Distractor). (C) had leaved (Structural Error) wrong V3 form.
6 (A) checked
- Why it is correct (The Key): “Realized” and “checked” are two consecutive actions in the past. When you discover something at the exact moment of looking, both verbs are in the Past Simple.
- Error Analysis: (B) had checked (Common Mistake) implies the checking happened before the realization, disrupting the logical flow of discovering an error upon looking. (C) have checked (Strong Distractor). (D) was checked (Structural Error).
7 (A) had misread
- Why it is correct (The Key): The false belief (“I thought” – Past Simple) was caused by an action that happened previously: misreading the email.
- Error Analysis: (B) misread (Common Mistake). (C) have misread (Strong Distractor). (D) had misreading (Structural Error).
8 (B) had finished
- Why it is correct (The Key): “By the time” always establishes a timeline where the second action is completed before the first action. The presentation finished before the computer was turned on.
- Error Analysis: (A) finished (Common Mistake). (C) have finished (Strong Distractor). (D) had finish (Structural Error).
9 (D) had forgotten
- Why it is correct (The Key): The feeling of unprofessionalism (“felt” – Past Simple) is the result of an earlier mistake (forgetting the briefing).
- Error Analysis: (A) forgot (Common Mistake). (B) have forgotten (Strong Distractor). (C) had forgot (Structural Error) requires the V3 “forgotten”.
10 (B) had damaged
- Why it is correct (The Key): The power outage (“went out” – Past Simple) was the result of a storm that hit “earlier that night” (Past Perfect).
- Error Analysis: (A) damaged (Common Mistake). (C) has damaged (Strong Distractor). (D) had damage (Structural Error).
11 (C) had deleted
- Why it is correct (The Key): The inability to find the link (“couldn’t find” – Past Simple) was due to an action completed “yesterday” (Past Perfect relative to the morning).
- Error Analysis: (A) deleted (Common Mistake). (B) have deleted (Strong Distractor). (D) had delete (Structural Error).
12 (A) had already concluded
- Why it is correct (The Key): “By the time” dictates that the meeting’s conclusion happened before the coffee was ordered.
- Error Analysis: (B) already concluded (Common Mistake). (C) has already concluded (Strong Distractor). (D) had already conclude (Structural Error).
13 (B) had entered
- Why it is correct (The Key): Being locked out (“was” – Past Simple) was the direct consequence of three earlier, completed attempts.
- Error Analysis: (A) entered (Common Mistake). (C) have entered (Strong Distractor). (D) had entering (Structural Error).
14 (D) had set
- Why it is correct (The Key): The employee is emphasizing a failed prior intention. They had set the alarm (Past Perfect), but a later event (battery dying – Past Simple) ruined the plan.
- Error Analysis: (A) set (Common Mistake) loses the nuance of a completed preparation that was subsequently interrupted. (B) have set (Strong Distractor). (C) had setting (Structural Error).
15 (C) did I realize
- Why it is correct (The Key): When a sentence starts with “Only after,” it requires subject-auxiliary inversion in the main clause. The realization happened after the text, so it uses the Past Simple inversion (“did I realize”).
- Error Analysis: (A) I realized (Common Mistake) lacks inversion. (B) had I realized (Strong Distractor) uses the wrong tense; you cannot realize something before the event that makes you realize it. (D) I had realized (Structural Error).
16 (A) had intended
- Why it is correct (The Key): Using the Past Perfect with verbs like intend, hope, plan shows an intention that was unfulfilled because something else happened (the software update).
- Error Analysis: (B) intended (Common Mistake) is acceptable in casual speech but “had intended” is the precise grammar used to show thwarted plans. (C) have intended (Strong Distractor). (D) had intending (Structural Error).
17 (C) had disconnected
- Why it is correct (The Key): The embarrassment (“was” – Past Simple) was about a fact that had already occurred in the background (the disconnection).
- Error Analysis: (A) disconnected (Common Mistake). (B) has disconnected (Strong Distractor). (D) had disconnect (Structural Error).
18 (B) hadn’t received
- Why it is correct (The Key): The assumption (“assumed” – Past Simple) was based on the prior non-occurrence of an event (not receiving the email).
- Error Analysis: (A) didn’t receive (Common Mistake). (C) haven’t received (Strong Distractor). (D) hadn’t receive (Structural Error).
19 (A) had never missed
- Why it is correct (The Key): “Prior to this incident” sets a strict boundary in the past. We use the Past Perfect to look back from that past point all the way to the beginning of the employee’s tenure.
- Error Analysis: (B) never missed (Common Mistake). (C) have never missed (Strong Distractor) mixes present perfect into a sentence anchored in the past (“Prior to this incident”). (D) had never missing (Structural Error).
20 (B) had been
- Why it is correct (The Key): The IT support confirmed (Past Simple) a mistake that occurred prior to the phone call. The Past Perfect Passive is required.
- Error Analysis: (A) was (Common Mistake). (C) has been (Strong Distractor). (D) had being (Structural Error).
GRAMMAR POINTS TO REMEMBER
- Explaining Causes in the Past: In professional communication (like apology emails), you often state what happened (the consequence) in the Past Simple and explain the cause or reason in the Past Perfect.
- Example: I missed the meeting (Consequence – Past Simple) because I had forgotten to set my alarm (Cause – Past Perfect).
- Unfulfilled Plans: To politely explain that you tried to do the right thing but failed, use the Past Perfect with verbs like plan, hope, intend, expect.
- Example: I had intended to join early, but my computer crashed.
- The “By the time” Rule: This phrase is a massive clue. It means “before a certain point in the past.” The action following “by the time” is Past Simple, and the other action is Past Perfect.
- Example: By the time I logged in, the meeting had ended.
- Consecutive Actions vs. Background Actions: * If actions happen one right after another (Action 1 -> Action 2), use the Past Simple for both. (I checked my calendar and realized my mistake.)
- If you are talking about a past event, and you need to mention something that happened before that event, use the Past Perfect. (I realized that I had misread the email.)
