Which sentence correctly uses the colon?

Correct Answer: A

Rationale: The correct answer is A: "She had one wish: to visit Paris." A colon is used after a complete sentence to introduce a list, quotation, or explanation. In choice A, the colon is appropriately used after the complete sentence 'She had one wish' to introduce the explanation 'to visit Paris.' Choices B, C, and D incorrectly place the colon in positions that do not follow a complete sentence or do not properly introduce an explanation, making them grammatically incorrect.

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: 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.
