What is the purpose of the passage?
- A. To express emotions
- B. To inform about Clara Barton's life and achievements
- C. To persuade readers to support the Red Cross Organization
- D. To entertain with fictional tales
Correct Answer: B
Rationale: The correct answer is B: 'To inform about Clara Barton's life and achievements.'

Why do cicadas make a buzzing sound?
- A. To orient via echolocation
- B. To attract a mate
- C. To locate a food source
- D. To ward off predators
Correct Answer: B
Rationale: Cicadas make a buzzing sound primarily to attract a mate. This sound is a mating call produced by the males to attract females for reproduction. While echolocation is used by some animals like bats for navigation, cicadas do not use buzzing for orientation. Buzzing is not related to locating a food source or warding off predators in the case of cicadas.
Which of the following evidence from the passage supports the inference that providing nap rooms at work can improve employee productivity?
- 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.
- C. Many successful companies have adopted the practice of work naps, in industries like tech, manufacturing - even NASA!
- 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. Choice D states the intention to provide nap rooms for employees but does not provide direct evidence of productivity improvement.
What is the main argument presented in the passage?
- A. The custom of tipping should be abolished in favor of paying servers a living wage
- B. Tipping enhances service quality in restaurants
- C. Servers' pay should be determined by their performance
- D. Customers derive pleasure from the custom of tipping
Correct Answer: A
Rationale: The correct answer is A: 'The custom of tipping should be abolished in favor of paying servers a living wage.' The rationale is that the passage argues for eliminating tipping and ensuring servers receive a fair wage. This is supported by the idea that servers should be paid adequately rather than relying on tips. Choice B is incorrect because the passage does not support the idea that tipping enhances service quality; it argues for a living wage instead. Choice C is incorrect as there is no mention of paying servers based on performance in the passage. Choice D is incorrect as the passage does not focus on customers' enjoyment of tipping but rather on the need to abolish the practice for fairer wages.

- A. Barton works as a federal patent clerk
- B. Barton travels to Europe

- D. Barton works on the frontlines of the Civil War
Correct Answer: D
Rationale: Based on the timeline provided, Barton working on the frontlines of the Civil War is the second event to occur.

Barton's travel to Europe and identification of anonymous soldiers happened after her service on the frontlines of the Civil War, making them later events in the timeline.
