3. Based upon the contextual evidence provided in the passage above, what is the meaning of the term enterprise in the third paragraph?

• A. Company
• B. Courage
• C. Game
• D. Cause

Correct answer: A

Rationale: In the third paragraph, the term 'enterprise' is used in the context of a group of travelers embarking on a journey together. In this context, 'enterprise' refers to a company or a group of people rather than courage, game, or cause. The word 'enterprise' is commonly used to denote a business organization or company, aligning with the idea of a group traveling together for a common purpose. 'Courage' and 'cause' do not fit the context of the travelers' journey, and 'game' is unrelated to the activities described in the passage.

4. As used in the passage, what does the word 'depressed' most nearly mean?

• A. Very unhappy
• B. Decreased appreciably
• C. Exhaled hard
• D. Pushed down

Correct answer: D

Rationale: In this context, 'depressed' means 'pushed down' as it refers to the action of pushing down the plunger to force out the clog in the pipe. The word 'depressed' is used to describe the physical action of pressing down, not to convey emotions like being very unhappy (choice A), to decrease appreciably (choice B), or to exhale hard (choice C), making these choices incorrect.

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

• A. A survey of high school students' foreign language preferences
• B. A comparison of the correlation between learning a second language at home and subsequent job placement rates
• C. A survey that asks parents about the foreign language they want 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: Choice D is the correct answer as it can provide evidence to support the claim made in the passage that high school graduates who studied a foreign language are more likely to be accepted to college. This choice aligns with the argument presented in the passage, making it a useful source. Choices A and C focus on opinions rather than concrete evidence of the impact of studying a foreign language on future success. Choice B is not directly relevant as it talks about learning a second language at home, while the passage specifically discusses the importance of studying a foreign language in high school.
