| Option | Meaning and use | Example |
|---|---|---|
| (1) Once (answer) | Once as a conjunction means as soon as or from the moment that. The action in the main clause follows directly. | Once you lose someone's trust, it is very hard to win it back. |
| (2) Since | 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. | Since it was raining, we stayed indoors. |
| (3) Although | contrast (in spite of the fact that). There is no contrast between a wrong choice and regret. | Although he was tired, he kept working. |
| (4) While | While means during the time that, or shows contrast. The regret does not last only while the choice is being made. | While she was cooking, the phone rang. |
