In the sentence, "We will depart as a class, but when we arrive we will split up into small groups," which part(s) is/are prepositional phrase(s)?

Correct Answer: D

Rationale: The prepositional phrases in the sentence are 'as a class' and 'into small groups,' making choices (a) and (c) correct. The phrase 'when we arrive' is not a prepositional phrase but rather a subordinate clause indicating a time. Prepositional phrases typically begin with a preposition (as, into) and end with a noun, pronoun, gerund, or clause. Therefore, the correct answer is option D, as it correctly identifies the prepositional phrases in the sentence.

Correct Answer: B

Rationale: The sentence is considered a complex sentence because it consists of an independent clause ('The tall man entered the restaurant, walked to the back, and sat down alone at the smallest table farthest away from the staff and other patrons') and a dependent clause beginning with 'wearing a black raincoat, a yellow hat, and one red shoe.' The dependent clause cannot stand alone as a complete sentence. Choice A is incorrect because a simple sentence contains only one independent clause. Choice C is incorrect as a compound sentence consists of two or more independent clauses. Choice D is incorrect as a compound-complex sentence contains two or more independent clauses and at least one dependent clause.

Correct Answer: B

Rationale: The sentence consists of one dependent clause, 'Although Ted had an impressive education,' which introduces a condition. It also contains two independent clauses: 'he had little experience working with individuals,' which presents a fact, and 'which made him less effective at relating to them,' which provides additional information. Therefore, the correct answer is B. Choice A is incorrect because it incorrectly identifies the number of independent and dependent clauses. Choice C is incorrect as it wrongly states that there are no dependent clauses in the sentence. Choice D is incorrect as it does not accurately represent the structure of the sentence.

Correct Answer: A

Rationale: This sentence correctly uses commas to set off the nonrestrictive phrase 'my pet bird' in between the name 'Maya' and the rest of the sentence. Nonrestrictive phrases provide additional information but are not essential to the sentence's meaning. Choice B has a missing comma after 'Peter' to separate the list of names correctly. Choice C should use commas, not dashes, to separate the items in the list. Choice D lacks a comma after 'project' to separate the clauses in a compound sentence.

Correct Answer: C

Rationale: Choice C would be the best beginning for an essay on 'Scientists Debate: Global Climate Change' because it sets the stage for discussion by introducing the potential consequences of Earth heating up and inviting readers to consider the implications. It also highlights the expertise of scientists who have dedicated their lives to understanding climate change, positioning them as credible sources for further discussion on the topic. The other choices either focus on the existing debate without providing a broader context (A and D) or present a narrow view on whether climate change is real and human-caused (B) without delving into the broader implications and discussions within the scientific community.
