- A. A consumer report about surcharges applied to customers' bills by mobile phone companies
- 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

- A. In the recent company-wide audits, many employees have reported fatigue at work.
- B. According to a 2008 study, napping for 60 minutes helped improve verbal memory, motor skills, and perceptual learning better than caffeine.

- D. Starting today, we will be providing a designated nap room in each office building near the gym and cafeteria to help employees take care of their bodies and minds, so they can be happier, healthier, and more productive.
Correct Answer: B
Rationale: The correct answer is B because the evidence from the 2008 study mentioned in the passage supports the inference that napping for 60 minutes can improve verbal memory, motor skills, and perceptual learning better than caffeine. This indicates that providing nap rooms at work can lead to improved productivity by enhancing cognitive functions. Choice A talks about the fatigue reported by employees but does not directly link it to productivity improvement. Choice C mentions that many successful companies have adopted the practice of work naps but does not specifically tie it to productivity enhancement.

Which of the following resources would help a reader gather information about economic trade during World War 1?
- A. News articles and textbooks
- B. Social media and photographs
- C. Atlases and works of art
- D. Almanacs and music
Correct Answer: A
Rationale: News articles and textbooks would provide the most relevant historical data on economic trade during World War 1. During significant events like World War 1, news articles would have reported on the economic aspects, such as trade disruptions and policies. Textbooks that cover the period would also delve into the economic impacts of the war. Choices B, C, and D are incorrect because social media, photographs, atlases, works of art, almanacs, and music are less likely to contain specific information about economic trade during World War 1. Social media did not exist during that time, photographs, atlases, works of art, almanacs, and music are more focused on visual, geographical, artistic, or general historical aspects rather than detailed economic data.
