Answer:
was sleeping
**Rule**: The **Past Continuous Tense** describes a longer background action that was interrupted by a shorter one. **Correct Usage**: The cat was in the middle of a long, peaceful sleep ('was sleeping') when it was suddenly interrupted by the dog's bark ('started barking'). **Incorrect Options**: (a) 'slept' (Simple Past) doesn't show the interruption. (c) 'had slept' means the sleep was finished. (d) 'had been sleeping' would emphasize the duration of sleep before the bark.

**Rule**: The **Simple Past Passive** (was/were + past participle) is used to describe a completed action in the past where the subject is the receiver of the action. **Correct Usage**: The message is the receiver of the action of sending. 'was sent' is the correct passive form for this single past event. **Incorrect Options**: (a) 'sent' is active voice. (c) 'had sent' is active and past perfect.

Past perfect is correct for the first action. **Incorrect Options**: (a) 'left' (Simple Past) is less precise. (b) 'was leaving' is illogical. (d) 'leave' is a present tense.

(b) 'weren't receiving' is incorrect. (d) 'don't receive' is a present tense.
