1. 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.

2. What is one way the author specifies that a person can try to be aware of their consumption of water and energy?

• A. Food that remains on your plate is a wasted resource, and you can always go back for a second helping.
• B. Locally grown food and other products manufactured within your community are the best choices.
• C. Don’t leave appliances or chargers plugged in when not in use.
• D. Participation begins with our everyday choices.

Correct answer: C

Rationale: The correct answer is C. The author specifically mentions in the passage that individuals should unplug appliances and chargers when not in use to reduce energy consumption. Choices A, B, and D are incorrect because they do not directly address the action of being aware of water and energy consumption. Choice A discusses food waste, choice B focuses on sustainable products and locally grown food, and choice D talks about participation in general without focusing on energy or water consumption.

3. When an atom gains or loses electrons, it becomes a(n):

• A. Molecule
• B. Isotope
• C. Ion
• D. Compound

Correct answer: C

Rationale: When an atom gains or loses electrons, it becomes an ion. Gaining or losing electrons alters the atom's electron count and charge, creating a positively or negatively charged ion. A molecule is formed when two or more atoms are chemically bonded. An isotope is a variation of an element with a different number of neutrons. A compound consists of two or more different elements chemically bonded together.

4. Which of the following structures is responsible for filtering lymph and supporting the immune system?

• A. Kidneys
• B. Lymph nodes
• C. Pancreas
• D. Liver

Correct answer: B

Rationale: Lymph nodes are responsible for filtering lymph and supporting the immune system. They contain immune cells that trap and destroy pathogens, making them crucial in immune response. The other choices, kidneys, pancreas, and liver, do not play a direct role in filtering lymph or supporting the immune system. The kidneys filter blood to remove waste and regulate electrolytes, the pancreas is involved in digestion and blood sugar regulation, and the liver is primarily responsible for detoxification and metabolism.

5. Which of the following correctly describes a strong acid?

• A. A strong acid completely ionizes in water.
• B. A strong acid donates more than one proton.
• C. A strong acid contains at least one metal atom.
• D. A strong acid will not decompose.

Correct answer: A

Rationale: The correct answer is A. A strong acid is defined as an acid that completely ionizes in water, meaning it dissociates fully into its constituent ions in solution. This characteristic differentiates strong acids from weak acids, which do not fully dissociate in water. Choice B is incorrect because the number of protons donated does not solely define the strength of an acid. Choice C is incorrect as strong acids are not defined by the presence of metal atoms, and Choice D is incorrect because all acids can decompose, but the strength of the acid is based on its ability to ionize in water.
