I hope this helps! Let me know if you have any more questions.

Sure! Here are the correct answers:

1. B) Even though the boy left early, it does not mean he was sick.

To check for grammatical correctness, we need to ensure that the main clauses are properly connected with a comma. In this case, the correct option adds a comma before the second clause.

2. B) Mom told the babysitter to prepare dinner, read us a story before bedtime, and put the dog in his crate around 10:00 p.m.

To ensure parallelism, we need to make sure all items in the series have the same grammatical structure. The correct option uses parallel verbs (prepare, read, put) for each item in the list.

3. B) Since the room has not been cleaned, my mother has been very upset.

The correct option adds a comma after the introductory clause to separate it from the main clause.

4. B) Sam's hobbies are singing, playing soccer, and playing video games.

To maintain parallel structure, all items in the list should follow the same grammatical pattern. The correct option uses the gerund form ("playing") for each item.

5. A) Bob finds skipping easier than hopping.

The correct option uses the comparative form "easier than" to maintain parallelism.

6. B) My brother likes to go to the mall, throw the football with our dad, and play video games on the computer.

To ensure parallelism, we need to use the same form of the verb for each item in the series. The correct option uses the base form ("play") for each item.

7. B) The girl was sad, confused, and lonely.

The correct option ensures that all items in the series are adjectives without any unnecessary additional verbs.

8. B) My dog's bad habits are chewing my toys, digging holes in my mom's favorite flowerbed, and running into my neighbor's yard.

To maintain parallel structure, all items in the list should follow the same grammatical pattern. The correct option uses the gerund form ("chewing," "digging," "running") for each item.

9. A) The little boy not only spilled his cup of juice but also his bowl of cereal.

In correlative conjunctions, the correct option positions the correlative conjunction "not only/but also" next to the words it connects.

10. B) Toni either wants chocolate ice cream or apple pie.

In correlative conjunctions, the correct option positions the correlative conjunction "either/or" next to the words it connects.

11. A) However, I didn't like the pizza.

The correct option provides a complete sentence with the conjunction "however" indicating contrast.

12. B) I studied for the spelling test; therefore, I will do well.

The correct option uses a semicolon to separate two independent clauses, or it could also use a comma followed by a coordinating conjunction like "and" or "therefore."

13. A) Our cat has nine kittens, only one is a female.

The correct option uses a comma to separate two independent clauses, creating a compound sentence.

14. A) Please look for my car keys; I can't find them.

The correct option uses a semicolon to separate two independent clauses.

15. A) The dog is scratching at the back door, let him inside.

The correct option creates a complete sentence by either adding a coordinating conjunction like "so" or "therefore" after the comma or using a semicolon to separate the clauses.

16. A) I either have to go to the store with my mom or stay home with my sister.

In correlative conjunctions, the correct option positions the correlative conjunction "either/or" next to the words it connects.

17. A) John's sister is attending Lehigh University; she is majoring in marketing.

The correct option uses a semicolon to separate two independent clauses.

18. B) Ronnie likes to bowl, ride horses, and watch ice hockey.

To maintain parallel structure, all items in the list should follow the same grammatical pattern. The correct option uses the base form ("watch") for each item.

19. B) Take the dog to the veterinarian; he is not feeling well.

The correct option uses a semicolon to separate two independent clauses.

20. A) Because she likes movies, I gave her complimentary movie passes.

The correct option creates a complete sentence by placing the dependent clause ("Because she likes movies") at the beginning of the sentence, followed by a comma.

21. A) Take either the brown sweater or the green sweater.

In correlative conjunctions, the correct option positions the correlative conjunction "either/or" next to the words it connects.

22. A) Therefore, he won't go.

The correct option provides a complete sentence with the conjunctive adverb "therefore" indicating result.

23. B) The hamburger has lettuce, tomatoes, and onions.

To maintain parallel structure, all items in the list should follow the same grammatical pattern. The correct option uses nouns for each item.

24. A) Jayne likes to shop, talk on the phone, and swim.

To maintain parallel structure, all items in the list should follow the same grammatical pattern. The correct option uses infinitive verbs ("shop," "talk," "swim") for each item.
