In the given scenario, what type of language should the student use when requesting an appointment with the instructor to discuss the research paper?

Correct Answer: C

Rationale: The correct answer is 'C: Email message starting with 'Dear Professor:'. In academic settings, it is essential to use formal and respectful language when addressing instructors. Starting the email with 'Dear Professor:' demonstrates professionalism and respect. Choice A is too informal for a professional setting. Choice B is vague and lacks the necessary level of formality. Choice D showcases unprofessional behavior by not acknowledging missing the appointment until later.

Correct Answer: B

Rationale: A research paper typically includes a bibliography of sources to document the research conducted. In this case, a research paper on the Great Migration would require a bibliography to cite the sources used. Choices A, C, and D do not typically require a bibliography as they are not research-based and focus more on personal or fictional content.

Correct Answer: A

Rationale: The correct use of a semicolon is to join two closely related independent clauses. Choice A is the only option that correctly uses a semicolon to connect two independent clauses: 'I have a big test tomorrow' and 'I can't go out tonight.' Choice B incorrectly uses a comma instead of a semicolon. Choice C adds an unnecessary 'and' after the semicolon, which disrupts the correct punctuation usage. Choice D introduces a contradictory conjunction 'but' after the semicolon, which is not necessary for the given context. Therefore, the correct answer is A.

Correct Answer: C

Rationale: The correct answer is C: 'I can't bear to see this.' The words 'bear' and 'bare' are homonyms, as they sound the same but have different meanings. Choice A does not contain a homonym; it correctly uses 'bear' in the context of enduring pain. Choice B uses 'bear' as a noun referring to the animal, not a homonym. Choice D uses 'bears' as a verb, not a homonym.

Correct Answer: C

Rationale: The correct answer is choice C: "I'm tired," she said. Direct speech involves quoting the exact words spoken by someone, typically indicated by quotation marks. In this sentence, the speaker's words are directly quoted within quotation marks, making it an example of direct speech. Choices A, B, and D do not directly quote the speaker's words within quotation marks, making them indirect speech examples.
