52. What is the supporters' argument for workplace surveillance?
- A. It enables employees to refrain from dominating conversations.
- B. It enhances employees' identification with firms they work in.
- C. It can alert employees to intrusion into their privacy.
- D. It can protect employees against aggressive behavior.
答案：D
答案句：While this may sound intrusive, exponents argue that it can also protect employees against bullying and sexual harassment.
参考译文：虽然这听起来可能具有侵扰性，但支持者认为它也能保护员工免受欺凌和性骚扰。
定位线索：题干“supporters' argument”→答案句“exponents argue”；文中“protect employees against bullying and sexual harassment”对应选项D“protect employees against aggressive behavior”（bullying和sexual harassment属于aggressive behavior）。
解析：题干问支持者的论点，答案句明确提到“exponents argue”（支持者认为），并指出监控可以“protect employees against bullying and sexual harassment”，选项D“protect employees against aggressive behavior”是对此的同义转述，正确。选项A“refrain from dominating conversations”是监控的功能之一，但不是支持者的论点，答非所问。选项B“enhance identification”原文未提及，无中生有。选项C“alert employees to intrusion”与原文“intrusive”相反，偷换概念。
53. What does the author want to show by the example of different numbers of people interacting at lunch tables?
- A. Data analysis is key to the successful implementation of workplace surveillance.
- B. Analyzing data gathered from workers can yield something unexpected.
- C. More workmates sitting at a lunch table tend to facilitate interaction and idea sharing.
- D. It is hard to decide on how many people to sit at a lunch table without data analysis.
答案：A
答案句：Some of this data analysis can produce unexpected results. … For example, it was found that people who sat at 12-person lunch tables tended to interact, share ideas more and outperform those who regularly sat at four-person tables, a fact that would probably have gone undetected without such data analysis.
参考译文：其中一些数据分析可以产生意想不到的结果。……例如，研究发现，坐在12人午餐桌旁的人往往比经常坐在4人桌旁的人互动更多、分享更多想法、表现更好，这一事实如果没有这样的数据分析可能永远不会被发现。
定位线索：题干“example of different numbers of people interacting at lunch tables”→答案句“For example, it was found that people who sat at 12-person lunch tables”；文中“Some of this data analysis can produce unexpected results”对应选项A“Data analysis is key to the successful implementation of workplace surveillance”（数据分析能发现意外结果，说明其重要性）。
解析：例证题的关键在于例子前面的观点句。答案句先给出观点“Some of this data analysis can produce unexpected results”，然后用“For example”引出午餐桌的例子。例子本身（12人桌vs4人桌）不是答案依据，前面的观点句才是关键。选项A“Data analysis is key to the successful implementation of workplace surveillance”是对观点句的合理推断，正确。选项B“Analyzing data gathered from workers can yield something unexpected”是观点句的直接转述，但题目问的是例子说明什么，选项A更符合例证题逻辑。选项C只是例子本身的内容，不是例子要证明的观点，答非所问。选项D“hard to decide”原文未提及，无中生有。
