1. Why is the electrical conductivity of a strong acid solution higher than that of a weak acid solution?

• A. Strong acids are more concentrated.
• B. Strong acids release more hydrogen ions.
• C. Weak acids are better at dissolving salts.
• D. Strong acids have a lower pH.

Correct answer: B

Rationale: The correct answer is B because strong acids release more hydrogen ions compared to weak acids. This higher concentration of ions in the solution leads to a higher electrical conductivity. Strong acids ionize completely in solution, producing a higher concentration of ions that can conduct electricity, whereas weak acids only partially ionize, resulting in a lower concentration of ions and lower electrical conductivity. Choice A is incorrect because the concentration of the acid does not directly determine its electrical conductivity. Choice C is incorrect as the ability to dissolve salts is not directly related to electrical conductivity. Choice D is incorrect because the pH of the solution, although related to acidity, does not directly determine the electrical conductivity.

2. Convert 0.875 to a fraction,

• A. 7\8
• B. 8\7
• C. 3\4
• D. 9\10

Correct answer: A

Rationale: To convert 0.875 to a fraction, express it as 875\10000. Simplifying this fraction by dividing both the numerator and denominator by 125 results in 7\80.

3. The plump old white cat basked in the warm sunlight. Which of the following options correctly punctuates the above?

• A. The plump, old, white cat basked in the warm sunlight.
• B. The plump, old, white, cat basked in the warm sunlight.
• C. The plump, old white cat basked in the warm sunlight.
• D. The plump old white cat, basked in the warm sunlight.

Correct answer: A

Rationale: The correct answer is A: 'The plump, old, white cat basked in the warm sunlight.' Commas should be used to separate coordinate adjectives describing the cat. In this sentence, 'plump,' 'old,' and 'white' are coordinate adjectives, each providing distinct information about the cat. Option B incorrectly places a comma after 'white,' creating a nonessential element. Option C lacks commas to separate the coordinate adjectives. Option D incorrectly places a comma after 'cat,' causing a punctuation error.

4. Which organ of the body compensates when a person's intake of vitamins decreases?

• A. Appendix
• B. Liver
• C. Pancreas
• D. Stomach

Correct answer: B

Rationale: The liver is the organ that compensates when a person's intake of vitamins decreases. It stores certain vitamins, such as vitamins A, D, E, K, and B12, and releases them when dietary intake decreases. This helps maintain the body's vitamin levels and functions. The other organs listed - Appendix, Pancreas, and Stomach - do not primarily play a role in compensating for a decrease in vitamin intake. The liver is crucial in maintaining vitamin balance, making it the correct choice in this context.

5. If you go to the market, please pick up some beef, carrots, and celery, and I will make some of that delicious stew we had last week. Which comma should be removed in the sentence above?

• A. The comma after the word 'market'
• B. The comma after the word 'beef'
• C. The comma after the word 'celery'
• D. The comma after the word 'delicious'

Correct answer: D

Rationale: The comma after 'delicious' is unnecessary as it separates the adjective 'delicious' from the noun 'stew'. In this case, 'delicious' is describing the type of stew, so the comma should be removed to maintain correct sentence structure. The other commas in the sentence are correctly used to separate items in a list and after introductory phrases, making them necessary for clarity and grammatical correctness.
