1. 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.

2. When sugar is heated, it breaks down into carbon and water vapor. This is an example of a:

• A. Combination reaction
• B. Decomposition reaction
• C. Double displacement reaction
• D. Single displacement reaction

Correct answer: B

Rationale: The correct answer is B: Decomposition reaction. When sugar is heated, it undergoes a decomposition reaction where it breaks down into simpler substances, carbon, and water vapor. In a decomposition reaction, a single compound breaks down into two or more simpler substances. This process is the opposite of a combination reaction where two or more substances combine to form a new compound. Choice A, Combination reaction, is incorrect because a combination reaction involves the combination of two or more substances to form a new compound, which is the opposite of what happens when sugar breaks down. Choices C and D, Double displacement reaction and Single displacement reaction, are incorrect as they involve different mechanisms where the atoms or ions of the reactants are exchanged, which is not the case in the breakdown of sugar into carbon and water vapor.

3. A researcher wants to investigate the relationship between family income and quality of medical care. Which statement provides the best reason to conduct this investigation?

• A. The researcher can identify affordable medical care to recommend to low-income families.
• B. The investigation can help identify individuals who are healthy so they can maintain their health.
• C. Results of this investigation may identify a group of people who do not receive quality medical care and could benefit from improved medical treatments.
• D. There is a valid reason to conduct this investigation.

Correct answer: C

Rationale: The correct answer is C because identifying a group of individuals who do not receive quality medical care can lead to targeted interventions to improve their access to better medical treatments. This investigation can help address disparities in healthcare and improve outcomes for those in need. Choice A is incorrect because the focus is on identifying those who lack quality medical care, not just affordable care. Choice B is incorrect as it misinterprets the purpose of the investigation, which is to improve medical care for those not receiving quality care, rather than maintaining the health of those already healthy. Choice D is too vague and does not provide a specific reason for conducting the investigation, unlike choice C which highlights the potential benefits of identifying individuals in need of improved medical treatments.

4. In the process of osmosis, the solvent moves from an area of...

• A. Low solute concentration to high solute concentration
• B. Hotter solution to colder solution
• C. Colder solution to hotter solution
• D. High solute concentration to low solute concentration

Correct answer: D

Rationale: In the process of osmosis, solvent molecules move from an area of high solute concentration to low solute concentration. This movement occurs to equalize the solute concentrations on both sides of the semi-permeable membrane. As water tends to move towards higher solute concentrations, the solvent moves in this direction to balance the concentrations and establish equilibrium. Choices A, B, and C are incorrect because osmosis involves the movement of solvent, not solute, and it moves towards the area of higher solute concentration, not lower. Therefore, the correct answer is option D.

5. Which word completes the sentence: 'Despite the storm, the concert ____ went on.'

• A. nevertheless
• B. however
• C. therefore
• D. nonetheless

Correct answer: D

Rationale: 'Nonetheless' is the correct word to complete the sentence as it emphasizes the continuation of the concert despite the contrary circumstance. 'Nevertheless' and 'however' are synonyms and indicate contrast rather than continuity. 'Therefore' implies a conclusion or result, which is not fitting in this context.
