Correct Answer: B

Rationale: The correct answer is 'B' - 'who.' 'Who' is the correct relative pronoun to introduce the clause 'who lives down the street,' providing more information about Mrs. Sato. The other choices, 'she,' 'which,' and 'whom,' are not appropriate relative pronouns for referring to a person in this context.

Correct Answer: D

Rationale: A mind map is a visual tool commonly used by writers to diagram ideas around a central concept. It helps in brainstorming and organizing thoughts by visually representing the relationships between different ideas. Choice A, a bar graph, is a graphical representation of data typically used to compare quantities. Choice B, a citation, is a reference to a source used in writing to give credit. Choice C, revision, refers to the act of reviewing, editing, and improving written work.

Correct Answer: C

Rationale: The sentence discusses evidence and clinical trials related to a specific therapy, indicating a scientific context. Scientific journal articles are known for presenting research findings, discussing evidence, and proposing further studies, making them the most suitable source for this type of information. Choices A, B, and D are incorrect because a motivational speech is more focused on inspiring and encouraging, a business memo typically deals with internal communication in organizations, and a personal blog reflects individual opinions or experiences, none of which align with the content and tone of the sentence provided.

Correct Answer: D

Rationale: The correct answer is 'thought.' 'Thought' is the correct past tense form of 'think.' In this sentence, 'thought' is used to indicate that the thinking process happened in the past before deciding to major in criminal justice. Choices A, B, and C are incorrect. 'Think' is the present tense form, 'thank' is a different verb with a different meaning, and 'thinked' is not a valid past tense form of 'think.'

Correct Answer: C

Rationale: The function of an adjective in a sentence is to describe or modify a noun. Adjectives provide more information about the noun they modify, such as its size, color, shape, etc. For example, in the sentence 'The tall building,' 'tall' is an adjective describing the noun 'building.' Choices A, B, and D are incorrect. Adjectives do not describe verbs (adverbs do that), connect clauses (conjunctions do that), or show action (verbs do that).
