Correct Answer: B

Rationale: Choice B introduces a specific claim that texting while driving is extremely dangerous by stating that 'there may be nothing more dangerous than texting while driving' and supports this claim with statistics on the number of deaths and injuries caused by texting while driving. It further emphasizes the impact by mentioning that the majority of texting drivers are teens. This approach of providing specific evidence helps to distinguish the claim from counterclaims and strengthens the argument. Choices A, C, and D do not introduce a specific claim supported by factual evidence and fail to distinguish it from potential counterclaims, making them less effective in presenting a strong argument.

Correct Answer: C

Rationale: The university determined the lunch schedule by considering when the most faculty members from each department usually enter the canteen. This information is provided in the announcement where it states that the schedules were recommended based on when members of each department should visit the canteen for lunch. Choice A is incorrect because the schedule was not arranged solely based on the department with the most faculty members. Choice B is incorrect as it implies checking with departments about the majority of faculty members entering the canteen, which is not explicitly mentioned. Choice D is incorrect as it simplifies the university's decision-making process, which involved considering the timing of faculty members from different departments entering the canteen.

Correct Answer: D

Rationale: The writer uses description as a structural pattern to show readers something instead of telling them. By vividly describing Thomas Jefferson, his life, achievements, and significance, the reader can form a mental image and understanding of who he was without being explicitly told. Description allows for a more engaging and immersive experience for the reader compared to being told facts directly. Choice A, 'Division,' involves breaking down a subject into parts for analysis and understanding, not necessarily showing something instead of telling it. Choice B, 'Narration,' is the act of telling a story or recounting events, which involves direct communication rather than showing through vivid details. Choice C, 'Definition,' is providing the meaning of something, which is informative but does not create a visual or immersive experience like description does.

Correct Answer: C

Rationale: A competitive salary is one that is similar to the average salary offered for comparable jobs. In the context of the job advertisement provided, a competitive salary is typically in line with what other employers are paying for similar positions to attract and retain the best talent in the industry. Choice A is incorrect because a competitive salary is not 'much less' than salaries offered for comparable jobs; it aims to be competitive. Choice B is incorrect as a competitive salary is not 'much greater' than salaries offered for comparable jobs; it aims to be fair and competitive. Choice D is incorrect as a competitive salary is not 'impossible to compare to' the salaries offered for comparable jobs; it is meant to be competitive and aligned with industry standards.

Correct Answer: B

Rationale: The commercial for cold medicine narrated by a man in a doctor's coat is the correct answer. This commercial claims professional authority without providing any evidence of the narrator's credentials. While the man may appear to be a doctor with his coat, there is no proof that he is actually a medical professional or that the product is recommended by experts. This lack of evidence can mislead consumers by giving the product an air of legitimacy and credibility without factual support. Choices A, C, and D do not fit the criteria as they involve a professional athlete endorsing a product, children enjoying a toy, and real consumers providing testimonials respectively.
