Correct Answer: A

Rationale: The correct answer is 'Despite.' 'Despite' is the best word to use in the sentence because it shows a contrast between Lorene having finished her coursework and her expectation to spend another year on campus. The word 'Despite' signals that there is an unexpected or contrary situation, emphasizing the contradiction between the two parts of the sentence. 'Although' (choice B) introduces a contrast but is not as strong as 'Despite' in highlighting the contradiction. 'Thus' (choice C) and 'However' (choice D) do not convey the intended contrast needed in this context, making them incorrect choices.

Correct Answer: A

Rationale: The phrase 'With torn pages' is misplaced in the sentence because it disrupts the flow of the sentence. Placing it at the beginning creates an awkward structure. It would be clearer to present the main action first before adding the detail about the torn pages. In this case, rearranging the sentence to 'I returned the book I'd just bought to the store with torn pages' would improve the sentence's coherence and readability. Choices B, C, and D are not misplaced in the sentence as they follow a logical order of action and description.

Correct Answer: B

Rationale: The word 'envelope' is used incorrectly in the sentence. The correct word should be 'folder,' as mentioned in the original sentence. An envelope is a flat paper container for a letter or documents, while a folder is a folded cover for papers or documents. 'Give,' 'whoever,' and 'replies' are all used appropriately in the sentence, so they are not the incorrect words.

Correct Answer: B

Rationale: The correct punctuation needed in the given sentence is a comma after 'class.' This comma is necessary to separate the two independent clauses 'Do not be afraid to ask questions in his class' and 'he is very approachable and explains things well.' Commas are used to separate independent clauses when they are joined by a coordinating conjunction like 'and.' Choice A, 'Hyphen,' is incorrect as a hyphen is not needed to connect any words in the sentence. Choice C, 'Apostrophe,' is incorrect as there is no possession or contraction being indicated in the sentence that requires an apostrophe. Choice D, 'Semicolon,' is incorrect as a semicolon is not used to join two independent clauses in this context; a comma followed by a coordinating conjunction is more appropriate.

Correct Answer: A

Rationale: The phrase 'of workers' is misplaced in the sentence because the preposition 'of' is unnecessary and disrupts the flow of the sentence. It creates redundancy as 'a number of workers' can be simplified to 'workers.' Removing this unnecessary prepositional phrase would make the sentence clearer and more concise. Choice B 'from my car window' is correctly placed as it provides context on where the observation was made. Choice C 'who were repairing the road' and Choice D 'alongside the mall' are essential parts of the sentence providing details about the workers' activity and location, respectively.
