Which of the following evidence from the passage supports the inference that providing nap rooms at work can improve employee productivity?

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. Choice D states the intention to provide nap rooms for employees but does not provide direct evidence of productivity improvement.

Correct Answer: D

Rationale: The correct statement about the passage is that beating egg whites involves stirring them vigorously. In the provided extract, it mentions 'Beat egg white until foamy. Stir in sugar, beat again until stiff peaks form.' This process of beating the egg whites until stiff peaks form requires vigorous stirring.

Choice B is incorrect as the passage mentions that plastic has many advantages despite its recycling challenges. Choice C is incorrect as the passage indicates that recycling plastic is difficult due to its low quality when recycled. Choice D is incorrect as the passage clearly states that plastic consumption by marine life like fish and birds is a reality, showing the impact of plastic pollution on marine ecosystems.

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.

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.
