Let's solve each question in the worksheet "Choosing the Right Conjunctions: Under the Sea..." and explain why each answer is correct.

1. Lucy stared at the ocean ________ thought about her dad.

Options:
a) as
b) once
c) nor
d) and

✔ Correct Answer: d) and

Explanation:
The sentence describes two actions happening simultaneously: Lucy stared and thought. "And" connects two independent actions.
- "as" could work in a different structure (e.g., "as she thought"), but here it doesn't fit grammatically.
- "once" implies time, not coordination.
- "nor" is used for negative contrasts and doesn't fit.

✔ Answer: d) and

2. Sandy put on her gear ________ the buzzer sounded.

Options:
a) than
b) when
c) how
d) that

✔ Correct Answer: b) when

Explanation:
This shows a time relationship — Sandy put on her gear at the moment the buzzer sounded. "When" introduces a time clause.
- "than" is for comparisons.
- "how" asks about manner.
- "that" is not appropriate here.

✔ Answer: b) when

3. Sue threw her net at the shark ________ it lunged at her.

Options:
a) so that
b) as much as
c) just as
d) than

✔ Correct Answer: c) just as

Explanation:
"Just as" means “at the very moment” or “exactly when.” It fits perfectly with the timing of the action — she threw the net the moment the shark lunged.
- "so that" implies purpose (e.g., to stop it), which isn’t clearly stated.
- "as much as" compares quantity.
- "than" is for comparisons.

✔ Answer: c) just as

4. Judy saw ________ the magic starfish went.

Options:
a) unless
b) where
c) whenever
d) yet

✔ Correct Answer: b) where

Explanation:
Judy saw the place the starfish went. "Where" refers to location.
- "unless" introduces a condition.
- "whenever" means "every time," which doesn't make sense here.
- "yet" is a conjunction meaning "but" or "still," not appropriate.

✔ Answer: b) where

5. Jon sailed his boat to the shore ________ the tide was rising.

Options:
a) during
b) or
c) whether
d) because

✔ Correct Answer: d) because

Explanation:
This sentence explains why Jon sailed to the shore — because the tide was rising.
- "during" would need a noun phrase (e.g., "during the rise").
- "or" introduces an alternative.
- "whether" introduces a choice or uncertainty.

✔ Answer: d) because

6. Sandy would have drowned ________ the Sea People had not helped her.

Options:
a) how
b) so
c) if
d) that

✔ Correct Answer: c) if

Explanation:
This is a conditional sentence expressing a hypothetical past situation.
“Sandy would have drowned if the Sea People had not helped her.” This is a standard third conditional structure.
- "how" asks about manner.
- "so" doesn’t connect clauses properly.
- "that" can be used in result clauses, but not here.

✔ Answer: c) if

---

7. You can't get into the Sea People's kingdom ________ they invite you.

Options:
a) unless
b) for
c) ever since
d) or

✔ Correct Answer: a) unless

Explanation:
"Unless" means "except if." The sentence means: You cannot enter unless they invite you.
- "for" gives a reason, but doesn’t fit here.
- "ever since" refers to time starting from a point.
- "or" doesn’t make logical sense.

✔ Answer: a) unless
