1. Which, if any, of the following statements are true?

• A. Water boils at approximately 100°C (212°F) at standard atmospheric pressure
• B. The boiling point is the temperature at which the vapor pressure is higher than the atmospheric pressure around the water
• C. Water boils at a lower temperature in areas of lower pressure
• D. A and C are true

Correct answer: D

Rationale: Both statements A and C are true. Water indeed boils at approximately 100°C (212°F) at standard atmospheric pressure. However, water boils at a lower temperature in areas of lower pressure due to the decreased atmospheric pressure, which affects the vapor pressure and boiling point of water. Statement B is incorrect because the boiling point is the temperature at which the vapor pressure equals the external pressure (atmospheric pressure in this case), not when it is higher.

2. How many grams are in 10 kilograms?

• A. 10,000 grams
• B. 100 grams
• C. 1000 grams
• D. 100,000 grams

Correct answer: A

Rationale: The correct answer is A: 10,000 grams. There are 1,000 grams in a kilogram. Therefore, to find the number of grams in 10 kilograms, you multiply 10 (kilograms) by 1,000 (grams/kilogram) to get 10,000 grams. Choice B (100 grams) is incorrect as it represents the conversion for 1 kilogram, not 10 kilograms. Choice C (1000 grams) is incorrect as it is equal to 1 kilogram, not 10 kilograms. Choice D (100,000 grams) is incorrect as it represents the conversion for 100 kilograms, not 10 kilograms.

3. What is the correct formula for calcium carbonate?

• A. CaSO₃
• B. CaCO₃
• C. Ca(OH)₂
• D. CH₃OH

Correct answer: B

Rationale: The correct formula for calcium carbonate is CaCO₃, which consists of one calcium (Ca) atom, one carbon (C) atom, and three oxygen (O) atoms. Therefore, choice B, CaCO₃, is the accurate formula for calcium carbonate. Choices A, C, and D do not represent the correct formula for calcium carbonate. Choice A, CaSO₃, is calcium sulfite, not calcium carbonate. Choice C, Ca(OH)₂, is calcium hydroxide, and choice D, CH₃OH, is methanol, none of which are correct formulas for calcium carbonate.

4. 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.

5. The development of the disease was 'insidious'. What does insidious mean in this context?

• A. Gradual
• B. Momentous
• C. Sudden
• D. Innocuous

Correct answer: A

Rationale: In this context, 'insidious' means progressing slowly but having harmful effects. This matches the meaning of 'gradual,' making it the correct answer. 'Momentous' means significant or important, which is not the meaning conveyed by 'insidious.' 'Sudden' means abrupt or unexpected, opposite to the slow progression indicated by 'insidious.' 'Innocuous' means harmless, which is the opposite of the harmful effects associated with an insidious disease.
