Which of the following words does the author use to express a derogatory tone?
- A. Predictable
- B. Noisy
- C. Delicate
- D. Roar
Correct Answer: A
Rationale: The correct answer is 'Predictable' because the author uses it in a negative context to imply something as uninspired or lacking creativity. In the passage, the author mentions that following rules can make writing difficult, contrasting writers who adhere to rules with those who break them to succeed. 'Predictable' reflects a derogatory tone as it suggests monotony or lack of originality. Choices B, C, and D do not convey a derogatory tone in the context of the passage. 'Noisy,' 'Delicate,' and 'Roar' are neutral or descriptive words that do not carry a negative connotation.

- B. A professional journal article about the incidence of generic hearing loss
- C. A university research paper about decibel limits of headphones and speakers
- D. A statistical report of mobile phone usage by a mobile phone company
Correct Answer: C
Rationale: The most relevant source for data on the effects of mobile use on consumers' hearing would be a university research paper about decibel limits of headphones and speakers. This source would provide specific information on how mobile use could potentially impact hearing due to the sound levels produced by headphones and speakers. Choice A discusses surcharges on bills, which is unrelated to hearing effects. Choice B focuses on the incidence of hearing loss in general, not specifically related to mobile use. Choice D, a statistical report on mobile phone usage, may not directly address the impact on consumers' hearing.
