Correct Answer: C

Rationale: 'Although' is a conjunction because it connects two clauses in the sentence. In the given sentence, 'although' introduces a dependent clause ('although I could use the opportunity more than I'd like to admit') and connects it to the independent clause ('Surely, he thought, I can't trust this enticing yet dubious offer'). This conjunction shows the contrast between the two ideas. Choices A, B, and D are incorrect because 'although' does not function as an adverb, preposition, or adjective in this context.

Correct Answer: D

Rationale: The correct answer is 'Suprarenal.' Breaking down the word parts, 'supra-' means above, and '-renal' pertains to the kidney. Therefore, 'Suprarenal' means above the kidney. Choice A, 'Interrenal,' is incorrect as 'inter-' means between or among. Choice B, 'Subrenal,' is incorrect as 'sub-' means below. Choice C, 'Intrarenal,' is incorrect as 'intra-' means within or inside.

Correct Answer: B

Rationale: The thesis statement of an essay is usually located in the introduction. This is where the author establishes the main idea or argument that will be developed throughout the essay. The conclusion (Choice A) summarizes the main points and restates the thesis but does not introduce it. Body paragraphs (Choice C) provide supporting details and arguments, while the bibliography (Choice D) lists the sources used in the essay, not the thesis statement.

Correct Answer: C

Rationale: Choice C is the correct answer because it properly uses quotation marks to indicate a direct quote within the sentence ('My history presentation was great!'). Choices A, B, and D contain direct quotes but fail to use quotation marks, making them incorrect. In choice A, the direct question 'How was your day?' should be enclosed in quotation marks. In choice B, the direct quote 'It was awesome.' should also be enclosed in quotation marks. In choice D, the direct statement 'That's wonderful!' should be enclosed in quotation marks.

Correct Answer: D

Rationale: The correct answer is D, 'chocolate cookies and vanilla cupcakes.' In this sentence, the friendly baker is the subject, 'offered' is the verb, and 'chocolate cookies and vanilla cupcakes' receive the action of the verb, making them the direct object. Choices A, B, and C do not directly receive the action of the verb 'offered,' so they are not the direct object. Choice A is the verb phrase, choice B is a prepositional phrase, and choice C is the subject of the sentence.
