In the sentence "Bess, who can draw beautifully, loves art; but Grace, who thinks very logically, prefers science," what type of sentence structure is being used?

Correct Answer: C

Rationale: The correct answer is C, complex. This sentence contains an independent clause ('Bess loves art') and a dependent clause ('who can draw beautifully'). The dependent clause relies on the independent clause for context and cannot stand alone as a complete sentence. The connection between the clauses is established by the relative pronoun 'who.' Choices A, B, and D are incorrect. It is not a compound-complex sentence as it lacks multiple independent clauses and a dependent clause, respectively. It is not a compound sentence since it does not have two independent clauses joined by a coordinating conjunction. Lastly, it is not a simple sentence because it contains both an independent and a dependent clause, making it more complex than a simple sentence.

Correct Answer: B

Rationale: Option B provides a clear and grammatically correct explanation for why the majority of survivors came from first class - they were able to reach the deck fastest to get a seat on a lifeboat. The phrase 'Because of this' properly introduces the reason that follows. In Option A, a comma after 'Because' is unnecessary and disrupts the flow of the sentence. In Option C, 'Because this' is incomplete and lacks proper connection to the subsequent clause. Option D, similar to Option C, lacks clarity due to the absence of a full linking phrase. Therefore, Option B is the best choice as it conveys the explanation effectively and without grammatical errors.

Correct Answer: D

Rationale: The prefix 'aero' is derived from the Greek word 'aēr,' which means air. In words like 'aerobics' and 'aeronautics,' the prefix 'aero' refers to air-related activities or concepts. Therefore, 'air' is the correct meaning of the prefix 'aero.' Choices A, B, and C are incorrect. 'Light' does not relate to the prefix 'aero,' 'speed' and 'distance' are not associated with the concept of air as in 'aero,' making them incorrect answers.

Correct Answer: A

Rationale: 'Egregious' means outstandingly bad or shocking. Among the given choices, 'thoughtless' is the best substitution that captures a similar meaning. This is because 'thoughtless' implies actions or errors committed without careful consideration, which aligns with the negative connotation of the word 'egregious' in the sentence. 'Bizarre' (choice B) means strange or unusual, not necessarily bad. 'Minor' (choice C) means of lesser importance or seriousness, which contrasts with the strong negativity of 'egregious.' 'Flagrant' (choice D) means obviously offensive or bad, but it does not fully capture the sense of shock and outstandingly bad conveyed by 'egregious.'
