Here are the official solutions:
Q1. Which of the following, if true, would most strengthen the argument that Toyota’s focus on quality and teamwork was the primary reason for the cultural transformation at NUMMI?
Correct Answer: (D)
Explanation:
• (A): Incorrect. While increased job satisfaction is positive, this does not specifically demonstrate how Toyota’s focus on quality and teamwork led to the cultural transformation at NUMMI. The improvement could be due to a variety of factors unrelated to teamwork.
• (B): Incorrect. Although this suggests that NUMMI’s transformation was unique, it does not provide direct evidence that quality and teamwork were responsible for the change. It offers a comparison, but not the critical link to the argument in question.
• (C): Incorrect. An increase in production output is a beneficial outcome, but this does not necessarily indicate that quality and teamwork were the driving forces behind the transformation. Production increases could be attributed to several factors unrelated to cultural changes.
• (D): Correct. This option directly supports the argument that teamwork and continuous improvement programs, part of Toyota’s approach, transformed the plant’s culture. Employees moving from resistance to active participation clearly reflects a change driven by Toyota’s focus on quality and teamwork.
• (E): Incorrect. While this provides background about the Takaoka plant’s success, it does not directly explain how the cultural transformation at NUMMI resulted from quality and teamwork. The focus is on Toyota’s history rather than NUMMI’s specific transformation.
Q2. Which of the following best expresses the main idea of the passage?
Correct Answer: (C)
Explanation:
• (A): Incorrect. This option is partially true, as the passage discusses how Toyota’s Production System helped address labor and production issues. However, the focus of the passage is broader, emphasizing both lean manufacturing and employee involvement in quality control. This choice narrows the focus too much.
• (B): Incorrect. This option focuses on the strategic goals of General Motors and Toyota in entering the joint venture. While these are mentioned in the passage, they are not the main idea. The passage focuses more on the cultural and operational changes at NUMMI rather than the motives behind the joint venture itself.
• (C): Correct. This option captures the key elements of the passage, which focuses on NUMMI’s transformation through lean manufacturing and the importance of employee involvement in quality control. These are central to the passage's theme, making this the best choice.
• (D): Incorrect. While Toyota’s no-layoff policy and equal treatment did improve labor relations, the passage is more concerned with the broader transformation brought about by Toyota’s Production System, not just specific labor policies.
• (E): Incorrect. Although the passage critiques General Motors’ top-down management approach, the focus is not solely on the failure of this approach. The main idea of the passage is about the positive changes introduced by Toyota, including the lean manufacturing philosophy and employee involvement, rather than simply illustrating the importance of consensus-based decision-making.
Q3. The passage describes how Toyota’s focus on teamwork led previously disengaged workers to actively contribute ideas. Which of the following is most analogous to this change in behavior?
Correct Answer: (C)
Explanation:
• (A): Incorrect. While teamwork is involved, the focus is on performance reviews rather than the cultural shift in behavior from resistance to active contribution.
• (B): Incorrect. Increased salaries leading to productivity does not reflect the teamwork and collaborative element, nor does it show previously disengaged workers becoming more involved.
• (C): Correct. This option closely mirrors the passage, with workers (nurses) moving from resistance to actively suggesting improvements in a team-oriented environment, similar to NUMMI workers.
• (D): Incorrect. While training can inspire innovation, this is more about developing skills rather than a shift in behavior through teamwork and collaboration.
• (E): Incorrect. Flexible hours do not necessarily involve teamwork or the shift from disengagement to active participation, which is key to the NUMMI transformation.
Q4. Why does the author describe the relationship between workers and supervisors as "adversarial" before the NUMMI transformation?
Correct Answer: (C)
Explanation:
• (A): Incorrect. This option generalizes to all American car plants, while the passage focuses specifically on the conditions at NUMMI before Toyota's involvement.
• (B): Incorrect. The passage does not place sole responsibility on the workers. The inefficiencies were a result of systemic management failures, not just worker behavior.
• (C): Correct. The passage emphasizes that the adversarial relationship stemmed from a lack of communication and teamwork, causing inefficiencies and poor production quality.
• (D): Incorrect. There’s no evidence in the passage suggesting that General Motors intentionally fostered conflict as part of its strategy.
• (E): Incorrect. The workers' negative attitudes were a result of management practices, not inherent behavior, according to the passage.
