Surely, he thought, I can't trust this enticing yet dubious offer, although I could use the opportunity more than I'd like to admit. 'Although' is which part of speech?

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: A

Rationale: Choice A is the correct answer. 'Therefore' is correctly used as a transition word with proper punctuation in this sentence. In a compound sentence like this, a semicolon is used before the transition word to connect two independent clauses. Choice B is incorrect because it lacks the necessary punctuation to separate the independent clauses. Choice C is incorrect as a colon is not typically used before a transition word in this context. Choice D is incorrect because 'and' does not function as a transition word in this sentence.

Correct Answer: A

Rationale: Choice A is the correct answer as it presents a clear thesis statement by comparing the achievements of Abel Tasman and James Cook. It establishes the main argument of the text, which is a key characteristic of a thesis statement. Choice B is too specific and only focuses on James Cook without presenting an argument. Choice C simply states a historical fact without presenting an argument or comparison. Choice D, while related to the topic, does not establish a clear argument or comparison between individuals, making it an incorrect 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.
