What is the best definition of economy as it is used in this passage?

Correct Answer: C

Rationale: The correct definition of 'economy' in this passage is 'efficient money management.' The passage emphasizes the importance of expending less than what is earned, which is a key aspect of efficient money management. Choice A, 'Exchange of money, goods, and services,' is too broad and does not capture the essence of the passage. Choice B, 'Delegation of household affairs,' is not directly related to the context of the passage. Choice D, 'Less expensive,' does not encompass the concept of managing money efficiently as discussed in the passage.

Correct Answer: A

Rationale: The passage reads like a self-help manual as it offers advice and guidance on managing money and achieving financial independence. It provides practical tips on making and keeping money, emphasizing the importance of living within one's means. The content is focused on providing instruction rather than personal experiences (autobiography), formal letters (epistle), or fictional storytelling (novel).

Correct Answer: C

Rationale: The correct answer is 'Explaining.' The passage is structured in an explanatory manner, providing a detailed account of how a plunger works. It explains the process step by step, from the initial depression of the plunger to the increase in pressure inside the clogged pipe. 'Modeling' and 'Observing' are not suitable choices as the passage does not involve creating models or direct observations. 'Hypothesizing' is also incorrect as the passage focuses on describing the functioning of a plunger rather than proposing or discussing potential hypotheses.

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.

Correct Answer: C

Rationale: The correct answer is 'C: As.' In the provided extract, the word 'As' is used to indicate the simultaneous action of depressing the plunger and pushing out the air. It establishes a connection between the two actions, showing that they occur together. Choice A, 'Out,' refers to the result of pushing the air out, not the action happening simultaneously. Choice B, 'Continued,' suggests a subsequent action rather than a simultaneous one. Choice D, 'Causes,' indicates a cause-and-effect relationship, not the action happening simultaneously like the word 'As' does.
