Select the most appropriate option to fill in the blank.
They could not reach the railway station before the train _______.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2, i.e. left.
The sentence uses a past-tense narrative describing two events:
“They could not reach the railway station before the train ___.”
Here, “they couldn’t reach” and “the train left” are two past simple actions where one occurred before the other. Standard grammar dictates that when stating the first event (“the train left”) occurred prior to the second (“they reached the station”), it remains in the simple past tense without needing past perfect. Multiple trusted sources illustrate this structure:
- A grammar explanation on whether to use past perfect or simple past notes that “The train had left before they reached the station” shows past perfect for the earlier action and simple past for the later action—but when simplifying, “The train left before we reached the station” is also correct.
- Another reference confirms that left is the appropriate choice in similar sentences.
The other options:
leave – present tense, incorrect.
has been leaving – incorrect form and tense.
has leave – grammatically incorrect.
