1. Which of the following distinguishes the isotopes of an element?

• A. Isotopes are atoms of the same element that have different ionic charges.
• B. Isotopes are atoms of elements within the same group on the periodic table.
• C. Isotopes are atoms of the same element that have different numbers of neutrons.
• D. Isotopes are atoms of the same element with different electron configurations.

Correct answer: C

Rationale: Isotopes are defined as atoms of the same element that have the same number of protons in their nucleus but different numbers of neutrons. This leads to variations in atomic mass for isotopes of an element. The different number of neutrons in isotopes results in differences in their atomic mass and properties while still belonging to the same element. Choice A is incorrect because isotopes do not have different ionic charges, they have the same chemical properties. Choice B is incorrect because isotopes are not atoms of elements within the same group on the periodic table; they are variants of the same element. Choice D is incorrect because isotopes of an element have the same electron configuration, differing only in the number of neutrons in the nucleus.

2. What is the average length of a human eyelash?

• A. 1 nanometer
• B. 1 centimeter
• C. 1 meter
• D. 1 kilometer

Correct answer: B

Rationale: The average length of a human eyelash is approximately one centimeter. A nanometer is too small to describe the length of an eyelash. A meter and a kilometer are much longer lengths and not suitable to describe the average human eyelash.

3. Which of the following sentences has correct pronoun-antecedent agreement?

• A. Because the students in the chemistry class did poorly on the exam, they had to take a make-up exam.
• B. Since the doctor has a lot of experience with this illness, she should know how to treat it.
• C. If the choir has a problem with my music, they can sing something else.
• D. The party of five was late for its reservation.

Correct answer: B

Rationale: Sentence B has correct pronoun-antecedent agreement with 'she' correctly referring to 'the doctor.' In sentence A, 'it' is unclear and doesn't have a clear antecedent. In sentence C, 'they' does not agree with 'choir,' which is a singular noun. In sentence D, 'their' should be 'its' to agree with the singular noun 'party.'

4. What is the mode of the numbers in the distribution shown in the table?

• A. 1
• B. 2
• C. 3
• D. 4

Correct answer: A

Rationale: The mode of a set of numbers is the value that appears most frequently. In the distribution shown in the table, the number '1' occurs more times than any other number, making it the mode. Choices B, C, and D are incorrect because they do not represent the number that occurs most frequently in the dataset.

5. What role does humor play in Wilde's critique of the aristocracy?

• A. To soften the harshness of the critique and make it more palatable.
• B. To make the critique more pointed and direct.
• C. To critique the aristocracy without alienating the audience.
• D. To entertain the audience with humor, while delivering a serious message.

Correct answer: C

Rationale: In Wilde's critique of the aristocracy, humor serves the purpose of critiquing without alienating the audience. By infusing humor into his work, Wilde can effectively highlight the flaws and absurdities of the upper classes while keeping the audience engaged and receptive. Option A is incorrect because the humor does not aim to soften the critique but rather to enhance its impact. Option B is incorrect as the humor in Wilde's work is not meant to make the critique more pointed and direct but rather more approachable. Option D is incorrect because while entertaining the audience, the primary function of humor in Wilde's critique is to provide a platform for social commentary without losing the audience's interest.
