What is the instructor's main purpose in writing this email to his students?

Correct Answer: C

Rationale: The instructor's main purpose in writing the email is to provide students with opportunities to improve their scores and avoid failing the course. The email outlines different options for extra credit projects that can help students make up for the low scores they received on the essay exam. This shows that the instructor is focused on helping students succeed rather than criticizing them (choice A), motivating them (choice B), or acknowledging the difficulty of the exam (choice D).

Correct Answer: D

Rationale: Based on the passage, the most logical conclusion is that students are most likely to earn the maximum extra credit by choosing the first option. The first option provides an extra credit project worth 150% of the point value of the essay exam, giving students more than enough chance to make up the difference and raise their overall score. The second and third options also offer the same 150% extra credit, but they involve more subjective scoring or group work, respectively, which may not ensure maximum extra credit. Therefore, choosing the first option is the best way for students to earn the most extra credit.

Correct Answer: B

Rationale: The main idea of the passage is that while making money may seem easy, managing it wisely is much more challenging. The author emphasizes the importance of spending less than what is earned to achieve financial stability. Choice A is incorrect as the passage focuses on the challenges of managing money, not on the ease of getting a job. Choice C is incorrect as Dr. Franklin is mentioned in the context of a quote about the simplicity of the road to wealth, not advocating getting a job in a mill. Choice D is incorrect as the passage does not primarily discuss spending money as the greatest temptation, but rather highlights the difficulty in managing money effectively.

Correct Answer: D

Rationale: The author's likely attitude towards a person unable to find employment would be incredulous. The passage emphasizes the abundance of job opportunities in the United States and suggests that finding employment should not be difficult for those willing to work. The author believes that with the numerous avenues of success and available vocations, anyone who is willing to engage in a respectable occupation should be able to find lucrative employment. Therefore, the author would find it hard to believe or be skeptical towards someone who claims they cannot find a job. Choice A, 'Descriptive,' is incorrect as the author's attitude is more judgmental than just describing a situation. Choice B, 'Conciliatory,' is incorrect as the author does not show any intention to reconcile or make peace with the situation of unemployment. Choice C, 'Ingenuous,' is incorrect as this term means innocent or naive, which does not align with the author's likely attitude of disbelief towards unemployment.

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.
