Choose the most appropriate option to fill in the blank in the given sentence:
_____you make a wrong choice with regard to your career, you will regret it for the rest of your life.
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → Once
Conjunction "once" (as soon as):
- Once as a conjunction means as soon as or from the moment that; the action in the main clause follows directly.
- This sentence: the moment a wrong career choice is made, lifelong regret follows, so Once fits.
- Complete sentence: Once you make a wrong choice with regard to your career, you will regret it for the rest of your life.
Example: Once you lose someone's trust, it is very hard to win it back.
Why the Other Options are Incorrect?
Option 2: Since — Incorrect. As a conjunction, since means because or from a past time; it would present the wrong choice as a known fact, not as a condition for what follows.
Example: Since it was raining, we stayed indoors.
Option 3: Although — Incorrect. Although shows contrast (in spite of the fact that); there is no contrast between a wrong choice and regret.
Example: Although he was tired, he kept working.
Option 4: While — Incorrect. While means during the time that, or shows contrast; the regret does not last only while the choice is being made.
Example: While she was cooking, the phone rang.
