1. What is 75% of 80?

• A. 35
• B. 45
• C. 70
• D. 60

Correct answer: D

Rationale: To calculate 75% of 80, you multiply 0.75 by 80, which equals 60. Therefore, the correct answer is 60. Choices A, B, and C are incorrect because they do not represent 75% of 80. Choice A (35) is close to 50% of 80, Choice B (45) is close to 56.25% of 80, and Choice C (70) exceeds 80.

2. What is another name for aqueous HI?

• A. hydroiodic acid
• B. hydrogen monoiodide
• C. hydrogen iodide
• D. hydriodic acid

Correct answer: D

Rationale: The correct name for aqueous HI is 'hydriodic acid.' When hydrogen iodide (HI) dissolves in water, it forms hydriodic acid. Therefore, 'hydriodic acid' is the appropriate term for aqueous HI. Choice A, 'hydroiodic acid,' is incorrect as it does not reflect the nature of the compound in the aqueous state. Choice B, 'hydrogen monoiodide,' is not a widely recognized term for this compound. Choice C, 'hydrogen iodide,' is the name for HI in the gaseous state, not when it's dissolved in water.

3. Which of the following is always true about molecules?

• A. They cannot travel through all cell membranes
• B. They move from low concentration to high concentration without using energy
• C. They move from high concentration to low concentration without using energy
• D. They cannot move

Correct answer: C

Rationale: The statement that molecules move from high concentration to low concentration without using energy is always true due to the natural process of diffusion. This movement occurs to reach equilibrium and does not require any additional energy input directly from the molecule itself. Choice A is incorrect because not all molecules can travel through all cell membranes. Choice B is incorrect as molecules typically move from high concentration to low concentration in a process known as passive transport. Choice D is incorrect as molecules are in constant motion due to factors like temperature and kinetic energy.

4. What is the overall tone of the essay?

• A. Apathetic
• B. Fascinated
• C. Discouraged
• D. Hopeful

Correct answer: C

Rationale: The overall tone of the essay is discouraged, as it conveys concern over the United States’ lower ranking in life expectancy and highlights various health issues contributing to this situation. The language used suggests frustration and disappointment regarding the country's health statistics, supporting option C as the correct answer.

5. What is the meaning of the word consensus as it is used in the last paragraph about Barefoot Running?

• A. Investigation.
• B. Purpose.
• C. Trepidation.
• D. Unanimity.

Correct answer: D

Rationale: "Consensus" refers to a general agreement or unanimity among individuals, particularly regarding the safety and effectiveness of barefoot running. The passage discusses differing opinions on this subject, indicating that there is not a unanimous agreement. Thus, choice D accurately captures the meaning of "consensus" within the context of the discussion.
