1. Which property of matter refers to the amount of space occupied by an object?

• A. Mass
• B. Volume
• C. Weight
• D. Density

Correct answer: B

Rationale: Volume refers to the amount of space occupied by an object. It is a measure of the three-dimensional space that an object occupies. Mass, on the other hand, refers to the amount of matter in an object, weight is the force of gravity acting on an object, and density is the mass of an object per unit volume. In this context, volume is the most appropriate choice as it directly relates to the amount of space an object occupies.

2. When defending a scientific argument, which technique is most effective?

• A. Citing other scientists who agree with your argument.
• B. Showing the results of scientific experiments that support your argument.
• C. Describing your scientific credentials, education, and past accomplishments.
• D. Pointing out that no one has come up with a proven alternative explanation.

Correct answer: B

Rationale: The most effective technique when defending a scientific argument is to show the results of scientific experiments that support your argument. In the realm of science, evidence-based support is crucial. By presenting concrete data and experimental results, you provide a convincing and reliable foundation for your argument. This method allows others to review, replicate, and verify the findings, thus strengthening the credibility of your position. Choices A, C, and D are not as effective as choice B because citing other scientists who agree with your argument (Choice A) may not carry the same weight as empirical evidence, describing your scientific credentials, education, and past accomplishments (Choice C) may not directly address the validity of your argument, and pointing out that no one has come up with a proven alternative explanation (Choice D) does not provide direct evidence supporting your argument.

3. Which of these examples shows incorrect use of subject-verb agreement?

• A. Neither of the cars is parked on the street.
• B. Both of my kids are going to camp this summer.
• C. Any of your friends are welcome to join us on the trip in November.
• D. Each of the clothing options is appropriate for the job interview.

Correct answer: A

Rationale: The sentence 'Neither of the cars is parked on the street' is incorrect in terms of subject-verb agreement. The subject 'Neither' is singular, so the verb should also be singular, which should be 'is' instead of 'are.' The correct sentence should be 'Neither of the cars is parked on the street.' Choices B, C, and D demonstrate correct subject-verb agreement. In choice B, 'Both' is plural and agrees with the plural verb 'are.' In choice C, 'Any' is singular and agrees with the singular verb 'are.' In choice D, 'Each' is singular and agrees with the singular verb 'is.'

4. Where is keratin found?

• A. It is a protein-digesting enzyme released by the stomach.
• B. It is released in the neuromuscular junction.
• C. It is a protein found in the hypodermis.
• D. It is a protein found in hair.

Correct answer: D

Rationale: Keratin is a structural protein found in hair, skin, and nails, providing strength and protection. It forms the main structural component of hair, making choice D the correct answer. Choices A, B, and C are incorrect because keratin is not an enzyme released by the stomach, not released in the neuromuscular junction, and not found in the hypodermis. Remember that keratin is primarily associated with structural support in epithelial cells.

5. After a twelve-hour workday, James was exhausted when he heard the news.

• A. .
• B. ;
• C. ,
• D. —

Correct answer: C

Rationale: The comma (,) is used to separate the introductory clause 'After a twelve-hour workday' from the main clause 'James was exhausted when he heard the news.' This punctuation correctly indicates the relationship between the two clauses without interrupting the flow of the sentence. Choice A (.), a period, would create two separate sentences, which is not appropriate in this context. Choice B (;) is too strong of a pause and semicolons are typically used to connect closely related independent clauses. Choice D (—) is an em dash, which is used to set off an abrupt break or interruption in the sentence, not to separate an introductory clause from the main clause.
