Select the option that most accurately maintains the correct tense sequence and logical chronology of actions.
By the time the committee arrived, the researchers completed their presentation, submitted the report, and were leaving the hall without waiting for the panel's feedback on their findings.
Solution
The question is testing for tense sequence and chronology with the structure "By the time [past action], [earlier past actions]."
When describing actions that were completed before another past action, we use the past perfect tense (had + past participle) for the earlier actions and simple past for the later action.
"By the time" signals that one action was completed before another past event occurred, requiring past perfect for the earlier actions.
Past Perfect (had + past participle): Shows an action completed before another past action.
Simple Past: Shows a completed action at a specific time in the past.
Option 1 → Mixes past continuous "were completing," past perfect "had submitted," and simple past "left" inconsistently.
Option 2 → Uses all simple past tenses, failing to show actions occurred before committee arrived.
Option 3 → Incorrectly uses present perfect "have completed/submitted" with past continuous "were leaving" after past tense.
Option 4 → Correctly uses past perfect "had completed," "had submitted," "had left" for all actions before "arrived."
Hence, Option 4 is correct.
