**Rule**: The **Simple Past Tense** is used to state a fact about a completed historical period. **Correct Usage**: 'lasted' is the correct Simple Past verb to describe the duration of a historical entity that no longer exists. **Incorrect Options**: (b) 'was lasting' is incorrect as 'last' is stative. (c) 'had lasted' would need another past reference. (d) 'lasts' is a present tense.

The cat ______ on the windowsill, watching the birds outside.
Answer:
was sitting
**Rule**: The **Past Continuous Tense** is used to describe an ongoing action or state that forms the main part of a scene in the past. **Correct Usage**: 'was sitting' describes the cat's continuous, peaceful action, creating a descriptive picture. **Incorrect Options**: (a) 'sat' (Simple Past) is a completed action. (b) 'had sat' and (d) 'had been sitting' would need another past reference point.

Answer:
had passed
**Rule**: The **Past Perfect Tense** is used for an action that was completed before a specific point in time in the past. **Correct Usage**: The storm passing ('had passed') was a completed event before the moment we 'were ready' to leave. **Incorrect Options**: (a) 'passed' (Simple Past) is less precise. (b) 'was passing' means it was still happening when they were ready. (d) 'passes' is a present tense.

I opened the window because the room ______ very stuffy.
Answer:
was
**Rule**: The **Simple Past Tense** ('was') is used to describe a state that was the reason for a past action. **Correct Usage**: The room 'was' stuffy (past state), which is why the speaker 'opened' the window (past action). The state and the action are closely linked in time. **Incorrect Options**: (b) 'had been' (Past Perfect) would imply the stuffiness was from an earlier time. (c) 'was being' would suggest the room was temporarily behaving in a stuffy way, which is illogical. (d) 'is' is a present tense.

Answer:
had been preparing
**Rule**: The **Past Perfect Continuous Tense** is used to emphasize the duration of an activity that was in progress before another past event occurred. **Correct Usage**: 'had been preparing' emphasizes the long, continuous preparation ('for an hour') that was taking place before the critic 'arrived'. **Incorrect Options**: (a) 'prepared' is the wrong tense. (b) 'was preparing' suggests the arrival happened during the preparation. (d) 'had prepared' (Past Perfect) focuses on completion.
546
When she was young, she ______ she could fly.
Answer:
believed
**Rule**: The **Simple Past Tense** is used to describe a past belief or state of mind, especially during a finished period like childhood. 'Believe' is a stative verb. **Correct Usage**: 'believed' correctly describes a belief she held in the past. **Incorrect Options**: (b) 'was believing' is incorrect as 'believe' is stative. (c) 'had believed' would be used if this belief was held before another past event. (d) 'believes' is a present tense.
547
While my parents ______ for the bus, they witnessed a street performance.
Answer:
were waiting
**Rule**: The **Past Continuous Tense** (was/were + verb-ing) is used to describe a longer, ongoing background action that was in progress when a shorter, completed action interrupted it. **Correct Usage**: The longer background action was 'were waiting'. This was interrupted by the shorter action 'witnessed'. The word 'While' often introduces the longer, continuous action. **Incorrect Options**: (a) 'waited' (Simple Past) would suggest the two actions happened sequentially, not simultaneously. (c) 'had waited' (Past Perfect) implies they finished waiting before the performance. (d) 'had been waiting' (Past Perfect Continuous) would emphasize the duration of waiting before something else happened.

(b) 'had used' would need a subsequent past reference. (d) 'have used' is a present tense.
549

Answer:
clapped
**Rule**: When two short actions happen at almost the same time in the past, the **Simple Past Tense** can be used for both. **Correct Usage**: The clapping ('clapped') and the curtain falling ('fell') happened simultaneously as concluding actions. **Incorrect Options**: (b) 'was clapping' implies the clapping was ongoing before the curtain fell. (c) 'had clapped' means the clapping was finished. (d) 'claps' is a present tense.

**Rule**: The **Past Continuous Tense** is used to ask about an activity that was in progress when another event happened. **Correct Usage**: 'were you listening' correctly asks about the ongoing activity at the moment the speaker 'came in'. **Incorrect Options**: (a) 'did, listen' (Simple Past) is for a completed action. (c) 'had, listened' and (d) 'had you been listening' would be used if the listening happened before the arrival.
