1. Which term is used interchangeably with negative variation?

• A. Non-correlation
• B. Direct correlation
• C. Inverse correlation
• D. Positive correlation

Correct answer: C

Rationale: The correct answer is C: Inverse correlation. Negative variation is synonymous with inverse correlation, indicating that as one variable increases, the other decreases. This relationship is the opposite of positive correlation, where both variables increase or decrease together. Non-correlation and direct correlation do not convey the concept of negative variation and are not interchangeable terms in this context. Non-correlation refers to variables that are not related or associated, while direct correlation indicates that as one variable increases, the other also increases. Positive correlation describes a relationship where both variables increase together, which is the opposite of negative variation.

2. Which enzyme found in saliva is responsible for breaking down carbohydrates into smaller molecules like sugars?

• A. Pepsin
• B. Amylase
• C. Lipase
• D. Trypsin

Correct answer: B

Rationale: The correct answer is B. Saliva contains an enzyme called amylase, which specifically targets carbohydrates and breaks them down into smaller molecules like sugars. Pepsin, choice A, is an enzyme found in the stomach that breaks down proteins, not carbohydrates. Lipase, choice C, is responsible for breaking down fats, not carbohydrates. Trypsin, choice D, is an enzyme that breaks down proteins in the small intestine, not carbohydrates. Therefore, choices A, C, and D are incorrect for this question.

3. Based on the contextual usage of this word, what is the most likely meaning of the prefix ante-?

• A. again
• B. good
• C. before
• D. together

Correct answer: C

Rationale: The prefix 'ante-' is commonly used to refer to something that comes before something else in terms of time, order, or position. In the provided sentence, the antechamber is described as a waiting area 'before' guests were allowed into the main hall. This usage indicates that 'ante-' in this context means 'before.' The other choices are incorrect: 'again' implies repetition, 'good' is unrelated, and 'together' does not fit the context of preceding or coming before something else.

4. The passage describes recent hurricane seasons as the most expensive on record. Which of the following statements gives the implied reason for this increased expense?

• A. Hurricane Katrina was an extremely violent storm.
• B. Valuable buildings were destroyed in New Orleans.
• C. The Atlantic Basin is entering an active period.
• D. Destruction of barrier islands and coastal wetlands has left the mainland exposed.

Correct answer: D

Rationale: The destruction of barrier islands and coastal wetlands has left the mainland exposed, leading to increased damage and expenses from hurricanes. This implies a direct reason for the increased cost of recent hurricane seasons. The other choices do not directly address the reason for the increased expenses. Choice A talks about the intensity of Hurricane Katrina but does not explain the overall trend of increased expenses. Choice B mentions buildings being destroyed, which is a consequence rather than a reason for increased expenses. Choice C discusses an active period in the Atlantic Basin but does not connect it to the increased costs of hurricane seasons.

5. Which of the following would be a useful source of information to determine the validity of the argument presented in the passage?

• A. A survey of high school students' preferences regarding foreign language requirements.
• B. A comparison of the correlation between a second language introduced at home and subsequent college acceptance rates.
• C. A survey asking parents to select the foreign language they would like their children to study in high school.
• D. A comparison of the correlation between high school students' study of a foreign language and subsequent college acceptance rates.

Correct answer: D

Rationale: The passage emphasizes the importance of studying a foreign language in high school for future success, including college acceptance rates and job market demand. To evaluate the argument's validity, it is crucial to examine the direct impact of studying a foreign language on college acceptance rates. Choice D is the correct answer because it directly addresses this aspect by comparing the correlation between high school students' study of a foreign language and subsequent college acceptance rates. This comparison would provide concrete evidence supporting or refuting the argument presented in the passage. Choices A, B, and C, though related to language education, do not directly assess the specific relationship between studying a foreign language in high school and college acceptance rates, making them less relevant for evaluating the argument's validity.
