The others are fine.

thank you, so number 3 would be B, and also 5 would be B?

Yes, 3 is B because the comma is needed at the end of an appositive phrase.

And yes, 5 is also B, as shown in the examples in the link I posted.

To answer these questions, you need to understand basic punctuation rules. In these examples, the correct answer is determined by the presence or absence of a comma or period.

1. The correct answer is (B) "summer;". The comma is required to separate the two independent clauses.

2. The correct answer is (B) "teacher;". The semicolon is used to separate the items in a list when those items themselves contain commas.

3. The correct answer is (A) "York". In this case, there is no need for any punctuation.

4. The correct answer is (A) "low". The sentence does not require any punctuation.

5. The correct answer is (A) "marine biologist.". The period is required to end the sentence.

6. The correct answer is (A) "(the play)". In this case, parentheses are used to indicate a specific clarification.

7. The correct answer is (B) "milk.... Stir in flour.". The ellipsis is used to indicate that the sentence is continued after the missing text.

By understanding these punctuation rules, you can determine the correct answer to each question.
