In which of the following situations is a citation needed?

Correct Answer: C

Rationale: The correct answer is C. A citation is necessary when using someone else's work, such as song lyrics, to support an argument in academic writing. In options A, B, and D, there is no need for a citation. Option A involves the professor teaching her own work, so no external citation is required. Option B refers to an original work by the speaker, which does not require citation. Option D mentions a well-known and accepted fact, which generally does not need a citation in academic writing.

Correct Answer: A

Rationale: The correct answer is A, Future progressive. 'Will be writing' indicates an ongoing action that will occur in the future, which is the future progressive tense. Choice B, Past perfect, is incorrect as it refers to an action completed before a specified time in the past. Choice C, Future simple, is incorrect as it refers to a simple future action without indicating ongoing progress. Choice D, Present perfective, is incorrect as it does not match the tense used in the sentence.

Correct Answer: C

Rationale: The informal tone and casual language, such as 'hey wait' and 'what are you up to tonight, anyways?' suggest that the speaker is a friend inquiring about the plans of another friend. This type of conversation is typical among peers and not in a professional setting, ruling out choices A and D. Choice B is incorrect because there is no indication of a debate or formal speech practice in the conversation.

Correct Answer: B

Rationale: 'Aisle' is the correct answer. A homophone is a word that is pronounced the same as another word but has a different meaning or spelling. In this sentence, 'I'll' is a homophone of 'aisle' as they sound the same but have distinct definitions and spellings. Choices A, C, and D do not fit the criteria of being homophones of 'I'll'.

Correct Answer: D

Rationale: The correct answer is D. A direct quotation from a reference source always requires a citation to give credit to the original author. Choices A, B, and C do not necessarily require citations. Choice A refers to information that is common knowledge or easily observed, which does not need a citation. Choice B pertains to summarizing information in one's own words, which should be attributed to the original source but does not require a direct citation. Choice C involves sharing a personal experience, which does not require a citation unless it includes specific data or information that needs to be attributed to a source.
