Correct Answer: C

Rationale: Option C combines the ideas in a clear and logical manner by explaining that Laura was on her way to a concert, got stuck in traffic, and thought she would miss the concert. This choice maintains the correct sequence of events, highlighting the cause-effect relationship between being stuck in traffic and potentially missing the concert. Choices A, B, and D either disrupt the logical sequence of events or introduce redundancy in the information provided, making them less effective in conveying the intended message.

Correct Answer: B

Rationale: The correct answer is B: Brainstorm interesting topics and ideas. Brainstorming is an essential initial step in the creative process of generating ideas for a group presentation. It allows team members to freely share thoughts, explore various angles, and come up with innovative concepts. Choice A, interviewing sources, typically comes after brainstorming to gather information. Choice C, developing an organized outline, usually follows brainstorming to structure the presentation content. Choice D, citing sources, is important but is not the first step in the idea generation process.

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: 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.'
