Explanation: The phrase "last election" indicates a definite time in the past, so the simple past tense is required.

Key idea: choose the simple past when the sentence refers to a specific past time.

• Correct choice — promised: Simple past matches the definite past time. Example: "At the time of last election, you promised us an adequate supply of electricity."

• "Would promise": Implies conditional meaning or future-in-the-past and is not appropriate with a specific past time marker.

• "Have promised": Present perfect links past actions to the present and is not used with definite past time expressions like "last election."

• "Had promised": Past perfect shows an action that occurred before another past action; no earlier past action is referenced here, so past perfect is unnecessary.

Tip: Look for time expressions (like "last election") to choose between simple past and perfect tenses.
