Question

By the time we reached the station, the train _____.

• A. left
• B. has left
• C. had left
• D. leaves

Hint:

Think of the Past Perfect as the "Past of the Past." If you are already talking about the past (reached), and something happened even earlier, use "had."

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
When two actions happened in the past, the action that occurred first is written in the Past Perfect Tense ($had + V3$), and the action that occurred later is written in the Simple Past Tense.
Step 2: Detailed Explanation:
The sentence mentions two events: "we reached the station" and "the train left".
The phrase "By the time" indicates that one action was already complete before the second one happened.
The train leaving happened before they reached the station.
Therefore, the first action (train leaving) must be in Past Perfect: "had left".
The second action (reached) is correctly in Simple Past.
Step 3: Final Answer:
The correct form is "had left". Therefore, option (3) is correct.
