He ______ his keys, so he couldn't open the door.
Answer:
had forgotten
**Rule**: The **Past Perfect Tense** is used for a past action that happened before another past action and caused it. **Correct Usage**: The action of forgetting the keys ('had forgotten') happened before he tried to open the door ('couldn't open'). The first action is the direct cause of the second. **Incorrect Options**: (a) 'forgot' (Simple Past) is also correct and very common, but Past Perfect emphasizes the prior action more clearly. (b) 'was forgetting' is illogical. (d) 'forgets' is a present tense.

I ______ in London for five years before I moved to Paris.
Answer:
had lived
**Rule**: The **Past Perfect Tense** is used to describe a completed action or state that took place over a period of time before another event in the past. **Correct Usage**: The period of living in London ('had lived') was completed before the speaker 'moved' to Paris. 'had been living' is also correct, emphasizing the continuity. **Incorrect Options**: (a) 'lived' (Simple Past) is also possible but less precise about the sequence. (b) 'was living' suggests the move happened while still living in London. (d) 'had been living' (Past Perfect Continuous) is also a strong correct answer.

I ______ my watch, so I didn't know what time it was.
Answer:
had broken
**Rule**: The **Past Perfect Tense** is used for a past action that is the reason for a subsequent past state. **Correct Usage**: I 'didn't know' the time (past state) because the action of breaking the watch ('had broken') had happened before that moment. **Incorrect Options**: (a) 'broke' (Simple Past) is also possible. (b) 'was breaking' is an ongoing process. (d) 'breaks' is a present tense.
67024
When the police arrived, the thieves ______. They were nowhere to be seen.
Answer:
had disappeared
**Rule**: The **Past Perfect Tense** is used for an action that was completed before another past action. **Correct Usage**: The thieves' disappearance ('had disappeared') was already a completed event before the police 'arrived'. **Incorrect Options**: (a) 'disappeared' (Simple Past) suggests they disappeared at the moment of arrival. (b) 'were disappearing' means they were in the process of leaving. (d) 'disappear' is a present tense.
67025
As soon as the sun ______, the birds started to sing.
Answer:
had risen
**Rule**: When two past actions happen in quick succession, with one being completed just before the other begins, the **Past Perfect Tense** can be used for the first action and the Simple Past for the second. The phrase 'As soon as' often uses this pattern. **Correct Usage**: The action of the sun rising ('had risen') was fully completed just before the birds began to sing ('started'). This shows a clear and immediate sequence. Simple Past ('rose') is also very common and acceptable in this structure. **Incorrect Options**: (b) 'was rising' implies they started singing during the sunrise. (d) 'rises' is a present tense.
67026
The sun ______ and a cool breeze was blowing.
Answer:
was setting
**Rule**: The **Past Continuous Tense** is used to describe two or more ongoing background actions or states that were happening at the same time in the past. **Correct Usage**: The sun 'was setting' and the breeze 'was blowing' were simultaneous, ongoing events creating a scene. **Incorrect Options**: (a) 'set' (Simple Past) is a completed action. (c) 'had set' would mean the sun was already down before the breeze started. (d) 'had been setting' would emphasize the duration before another event.

Answer:

**Rule**: The **Past Continuous Tense** is used to ask about an activity that was in progress when it was interrupted by another event. **Correct Usage**: 'were you doing' correctly asks about the ongoing activity at the moment the power 'went out'. **Incorrect Options**: (a) 'did, do' (Simple Past) is for a completed action. (c) 'had, done' and (d) 'had you been doing' are for actions before the interruption.
67028
Last summer, our family ______ a trip to the northern mountains.
Answer:
took
**Rule**: The **Simple Past Tense** is used for a completed action that happened at a specific time in the past. **Correct Usage**: 'Last summer' specifies a finished past period, so the Simple Past 'took' is the correct choice. **Incorrect Options**: (b) 'was taking' would describe the trip in progress. (c) 'had taken' would need another past reference. (d) 'has taken' is a present tense.
