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: A

Rationale: Choice A is the correct answer. The word 'relevant' is spelled correctly in this sentence, and the sentence is well-constructed. In Choices B, C, and D, the word 'relevant' is misspelled as 'revelant,' 'relevent,' and 'relavance' respectively. These incorrect spellings make Choices B, C, and D grammatically incorrect, thereby making Choice A the only correct option.

Correct Answer: C

Rationale: The correct answer is 'C: changeable.' This word is an exception to a common spelling rule where it retains the 'e' when adding the suffix '-able.' In contrast, choices A, B, and D follow standard spelling rules without exceptions.

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: The correct answer is A - 'Went to the store yesterday.' This sentence is a fragment because it lacks a subject. A complete sentence should have both a subject and a verb. Choice B, C, and D are all complete sentences as they have both a subject ('She') and a verb ('went'). Therefore, they are not fragments.
