Which of the following sentences correctly uses commas to set off a non-essential element?
- A. The teacher, who lives next door, will visit our class next week.
- B. The teacher who lives next door will visit our class next week.
- C. The teacher, who, by the way, lives next door, will visit our class next week.
- D. The teacher will visit our class next week, who lives next door.
Correct Answer: A
Rationale: The correct answer is A. In this sentence, the phrase 'who lives next door' is a non-essential element providing additional information about the teacher. It is correctly set off by commas. Choice B does not use any commas to set off the non-essential element, making the information essential to the sentence. Choice C uses an unnecessary comma before 'who,' which disrupts the flow of the sentence. Choice D incorrectly places the non-essential element at the end of the sentence without appropriate commas, making it less clear and concise.

What does the prefix poly- mean in the word polygon?
- A. Few
- B. Several
- C. None
- D. Many
Correct Answer: D
Rationale: The correct answer is D: 'Many.' The prefix poly- comes from the Greek word 'polus,' which means 'many.' Therefore, in the word polygon, poly- indicates a shape with many sides. Choices A, B, and C are incorrect because the prefix poly- does not mean 'few,' 'several,' or 'none,' but rather 'many.'
Based on the word choices in the following sentence, which of the following is the most likely meaning of the prefix per-?
- A. Across
- B. By
- C. With
- D. Through
Correct Answer: D
Rationale: The prefix 'per-' commonly means 'through,' indicating movement from one side to the other or completely through something. In this context, 'through' is the most fitting interpretation as it aligns with the idea of complete passage or thorough involvement. The other options do not convey the concept of going completely through something. 'Across' implies moving from one side to another but not necessarily all the way through. 'By' denotes proximity or secondary involvement rather than passage through. 'With' indicates accompaniment or association, which is not reflective of the prefix per- in terms of movement or completion.
Which of the following is a simple sentence?
- A. Phillippa walked the dog, and Primula gave the dog a bath.
- B. Phillippa walked and bathed the dog, and Primula helped.
- C. Phillippa walked the dog, while Primula gave the dog a bath.
- D. Phillippa and Primula walked the dog and gave the dog a bath.
Correct Answer: D
Rationale: A simple sentence contains only one independent clause. Choice D, 'Phillippa and Primula walked the dog and gave the dog a bath,' is a simple sentence as it consists of a single subject (Phillippa and Primula) and predicate (walked the dog and gave the dog a bath). Choices A, B, and C contain multiple clauses or conjunctions that create compound sentences, making them more complex and not fitting the criteria of a simple sentence.
Which of the following sentences contains a correct example of subject-verb agreement?
- A. All of the board members are in agreement on the issue.
- B. Each of the students was concerned about the test scores for the final exam.
- C. Neither of the children is at home right now.
- D. Any of the brownie recipes is perfect for the bake sale.
Correct Answer: A
Rationale: The correct answer is A. In this sentence, the subject 'all of the board members' is plural, and the verb 'are' agrees with it. In choice B, 'each of the students' is singular, so the verb should be 'was' instead of 'were.' Choice C should use 'is' instead of 'are' since 'neither of the children' is singular. In choice D, 'any of the brownie recipes' is singular, so 'is' should be used instead of 'are.' Therefore, only choice A demonstrates proper subject-verb agreement.
Julia is writing an essay about the influence of technology on interpersonal relationships. Which of the following sentences would NOT be a relevant supporting detail?
- A. Studies show that the more teenagers engage in social media, the less they engage with their peers.
- B. College students study and work on homework an average of 4-6 hours a day.
- C. Use of technology such as smartphones can lead to a lack of engagement in conversations.
- D. Some psychologists think that watching TV activates the same part of the brain as having an in-depth conversation.
Correct Answer: B
Rationale: In an essay focusing on the impact of technology on interpersonal relationships, details about college students' study habits and homework workload are not directly related to the influence of technology on relationships. Choices A, C, and D are more relevant as they directly address the impact of technology, such as social media engagement, smartphone usage affecting conversations, and the comparison between TV-watching and brain activity during conversations.
