1. Which state of matter has particles that are highly organized in a fixed pattern and vibrate in place?

• A. Solid
• B. Liquid
• C. Gas
• D. Plasma

Correct answer: A

Rationale: The correct answer is 'Solid.' Solids have particles that are tightly packed together in a fixed pattern, allowing them to vibrate in place. This highly organized structure gives solids a definite shape and volume. In contrast, liquids have particles that are close together but can move past each other, enabling them to flow and take the shape of their container. Gases have particles that are far apart and move freely in all directions, filling the entire space available to them. Plasmas, on the other hand, have highly energized particles that do not have a fixed pattern and are not confined by a definite volume or shape.

2. How many ounces are in one pint?

• A. 12 ounces
• B. 16 ounces
• C. 8 ounces
• D. 20 ounces

Correct answer: B

Rationale: The correct answer is B: 16 ounces. One pint is equivalent to 16 ounces. This is a common conversion in cooking and baking measurements. Choice A (12 ounces) is incorrect because it does not represent the correct conversion of pints to ounces. Choice C (8 ounces) is incorrect as it is not the correct equivalent for a pint. Choice D (20 ounces) is incorrect as it overestimates the number of ounces in a pint. Understanding these conversions is essential when following recipes or working with liquid measurements in various contexts.

3. The chemical equation below is unbalanced. When it is properly balanced, how many molecules of carbon dioxide (CO2) are produced for each molecule of propane (C3H8) in the reaction? 3C3H8 + 5O2 → 3CO2 + 4H2O

• A. One Half.
• B. Two.
• C. Three.
• D. Five.

Correct answer: B

Rationale: The balanced chemical equation for the combustion of propane is: 3C3H8 + 5O2 → 3CO2 + 4H2O. This equation shows that for every 3 molecules of propane (C3H8) consumed, 3 molecules of carbon dioxide (CO2) are produced. Therefore, when properly balanced, 3CO2 are produced for each molecule of propane used. Thus, the correct answer is B: Two. Choices A, C, and D are incorrect because they do not reflect the correct stoichiometry as determined by the balanced equation.

4. Which of the following is NOT a major division of the nervous system?

• A. Peripheral nervous system
• B. Central nervous system
• C. Somatic nervous system
• D. Autonomic nervous system

Correct answer: C

Rationale: The correct answer is C: Somatic nervous system. The major divisions of the nervous system are the central nervous system, which includes the brain and spinal cord, and the peripheral nervous system, which includes all the nerves outside of the central nervous system. The somatic nervous system, which controls voluntary movements and reflexes, is a part of the peripheral nervous system. The autonomic nervous system is another subdivision of the peripheral nervous system that regulates involuntary functions like heart rate and digestion. Therefore, the somatic nervous system is not a major division of the nervous system, making it the correct answer.

5. Which of the following represents an opinion statement on the part of the author?

• A. The problem with having a larger Bermuda Triangle is that it increases the odds of accidents.
• B. The area known as the Bermuda Triangle has become such a part of popular culture that it can be difficult to sort through the myth and locate the truth.
• C. The increase in ships from East Asia no doubt contributes to an increase in accidents.
• D. Most consider the Triangle to stretch from Miami to Puerto Rico and include the island of Bermuda.

Correct answer: C

Rationale: Choice C, 'The increase in ships from East Asia no doubt contributes to an increase in accidents,' represents an opinion statement made by the author. This statement reflects the author's belief or judgment about the impact of increased ships from East Asia on the occurrence of accidents in the Bermuda Triangle. The other choices, A, B, and D, provide factual information or general statements without expressing a personal opinion. Choice A discusses a potential consequence of a larger Bermuda Triangle, choice B highlights the cultural significance and difficulty in discerning truth about the Bermuda Triangle, and choice D describes the commonly accepted geographical boundaries of the Bermuda Triangle. Therefore, choice C is the correct answer as it represents an opinion statement on the part of the author.
