The mail carrier's job is to put the _____ in every mailbox on the block.

Correct Answer: B

Rationale: The correct answer is B: 'envelope.' The mail carrier typically delivers envelopes containing mail to every mailbox on the block. Envelopes are commonly used to protect and contain letters, making them the most suitable choice in this context. Choices A, C, and D are incorrect because while the mail carrier may deliver letters, packages, or documents, the most common item placed in mailboxes is an envelope containing mail.

Correct Answer: A

Rationale: The correct answer is A, 'While they were sleeping.' This is an incomplete sentence as it lacks a main clause. A complete sentence should have both a subject and a predicate to express a complete thought. In this case, the subordinating conjunction 'while' introduces a dependent clause that needs to be connected to an independent clause to form a complete sentence. Choices B, C, and D are complete sentences as they each contain a subject and a predicate, expressing a complete thought.

Correct Answer: D

Rationale: The sentence 'The spy had to snake his way onto the train' correctly uses 'snake' as a verb. In this context, 'snake' is used to describe the spy's action of moving cunningly and stealthily, similar to how a snake slithers, making it the appropriate choice where 'snake' functions as a verb. The other choices use 'snake' as a noun to refer to the reptile itself or its movement, not as a verb.

Correct Answer: A

Rationale: The correct answer is option A: 'Trying not to wake the baby,' he slowly opened the door. This option improves sentence clarity by placing the modifying phrase at the beginning of the sentence, which clearly indicates that the action of trying not to wake the baby is related to the act of opening the door slowly. Option B, 'He opened the door,' trying not to wake the baby, is incorrect because it separates the action from its modifier, leading to confusion about which action the phrase 'trying not to wake the baby' is referring to. Option C, 'He opened the door slowly,' trying not to wake the baby, is incorrect because it incorrectly places the modifier 'trying not to wake the baby' after the adverb 'slowly,' which disrupts the flow of the sentence. Option D, 'Slowly trying not to wake the baby,' he opened the door, is incorrect because it places the modifier in an awkward position at the beginning of the sentence, causing confusion about the intended meaning. Educationally, understanding sentence structure and placement of modifiers is crucial for effective communication in both writing and speaking. Placing modifiers in the correct position ensures clarity and coherence in conveying the intended message to the reader or listener.

Correct Answer: B

Rationale: In real estate, when an apartment is described as 'furnished,' it means that it comes equipped with furniture. This typically includes essential items like beds, sofas, dining tables, and more. Therefore, 'Equipped with furniture' is the correct meaning of 'furnished' in this context. Choices A, C, and D are incorrect because being 'furnished' specifically refers to the presence of furniture in the apartment, not renovation status, utilities, or decor style.
