Fill in the blank with the suitable word from the options given below:
It is mandatory to complete the work ____ you call it a day.
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → before
Conjunction of time:
- Before joins two clauses and shows that the first action must happen earlier than the second.
- This sentence: the work must be completed first; only then can one call it a day (stop working for the day). So "before" fits.
- Complete sentence: It is mandatory to complete the work before you call it a day.
Example: Switch off the lights before you leave the room.
Why the Other Options are Incorrect?
Option 1: after — Incorrect. After reverses the order: the work would be completed once the day's work is over, which makes no sense.
Example: We went home after the meeting ended.
Option 2: and — Incorrect. And only adds one idea to another; it shows no order in time, and "complete the work and you call it a day" is not grammatical.
Example: She finished the report and sent it to her manager.
Option 4: than — Incorrect. Than is used only after a comparative (better than, more than); there is no comparison here.
Example: This task is easier than the last one.
