1. What does 'm' stand for in the metric system?

• A. meter
• B. mole
• C. milli
• D. micro

Correct answer: A

Rationale: The correct answer is 'meter.' In the metric system, 'm' stands for meter, which is the base unit for length. Choice B, 'mole,' is a unit used in chemistry to represent an amount of substance. Choice C, 'milli,' represents a prefix indicating one-thousandth, and choice D, 'micro,' represents a prefix indicating one-millionth. Therefore, the correct choice is 'A: meter.'

2. Identify the adverb in the sentence: 'She quickly finished her homework.'

• A. She
• B. Finished
• C. Quickly
• D. Homework

Correct answer: C

Rationale: The correct answer is 'C: Quickly.' Adverbs modify verbs, adjectives, or other adverbs. In this sentence, 'quickly' describes how she finished her homework. Choice A 'She' is a pronoun, choice B 'Finished' is the verb, and choice D 'Homework' is a noun, making them incorrect choices for adverbs.

3. Which of the following is the antiparticle of a neutron?

• A. Antineutrino
• B. Positron
• C. Antiproton
• D. Electron

Correct answer: C

Rationale: The antiparticle of a neutron is an antineutron, which is composed of an antiproton and an antineutrino. The antineutrino (choice A) is not the antiparticle of a neutron. A positron (choice B) is the antiparticle of an electron, not a neutron. An electron (choice D) is a fundamental particle, not an antiparticle. Therefore, the correct answer is an antiproton (choice C), as it forms an antineutron when combined with an antineutrino.

4. 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.

5. Based on the passage, which conclusion can be drawn about the author?

• A. They are overly emotional and...
• B. They would rather be at a concert
• C. They go to the theater as often as possible
• D. They enjoy the decor of most theaters

Correct answer: C

Rationale: The correct answer is C. The passage does not mention anything about the author's emotional state or preference for concerts. However, it does discuss cicadas and their emergence, life cycle, and behavior. Therefore, the reader can conclude that the author is likely interested in cicadas and their natural history, indicating that they go to the theater as often as possible. Choice A is incorrect because there is no evidence regarding the author being overly emotional. Choice B is incorrect as there is no mention of the author's preference for concerts. Choice D is incorrect as the passage does not provide any information about the author enjoying theater decor.
