📘 Explanation of Each Conjunction Choice:

1. When — used to refer to a specific point in time when something happens.

> *“When it gets dark…”* — This is a general, recurring event; “when” fits naturally for habitual or scheduled actions.

2. As soon as — indicates that one action will happen immediately after another.

> *“I’ll call you as soon as I leave work.”* — Calling happens right after leaving work.

3. While — used to show two actions happening at the same time.

> *“I watered… while my husband mowed…”* — Both actions occurred simultaneously.

4. After — shows that one event happened following another.

> *“He arrived after everybody had gone home.”* — His arrival came later than others leaving.

5. Once — means “as soon as” or “when (a condition is met)”, often implying a single occurrence.

> *“You can repay me once it’s sold.”* — Repayment is conditional on the sale being complete.

6. Until — shows duration up to a certain point.

> *“He was headteacher until he retired…”* — His role ended at retirement.

7. Before — indicates an action must happen prior to another.

> *“Think carefully before you choose.”* — Thinking should come first.

8. As soon as — again, immediate sequence.

> *“I’ll tell you as soon as I get them.”* — Telling follows instantly upon receiving results.

9. While — simultaneous actions.

> *“I read… while I was waiting…”* — Reading and waiting happened together.

10. After — future action dependent on completion of another.

> *“We’ll go out after it stops raining.”* — Going out follows the end of rain.

11. Once — introduces a condition that triggers a future result.

> *“Once I pass… I’ll be qualified.”* — Passing exams is the trigger for qualification.

12. Until — emphasizes duration up to a specific time.

> *“Didn’t finish until 11pm.”* — Movie continued playing up to 11pm.

13. Before — action precedes another.

📌 Key Takeaways:

- When = at the time that (general or specific)
- As soon as = immediately after
- While = during the time that (simultaneous actions)
- After = following a past or future event
- Before = prior to an event
- Until = up to the point that (duration ends)
- Once = as soon as / when (conditionally, often with future implication)

These conjunctions help clarify the timing relationship between events — whether they happen before, after, at the same time, or under certain conditions.
