47. What does the suspension of Ant Group Co.'s stock offering suggest?
- A. All attempts to evade regulation are doomed to failure.
- B. All attempts to monopolize sales must be cracked down.
- C. All companies must be regulated by the government.
- D. All companies, domestic or foreign, are created equal.
答案：C
答案句：The draft rules followed the surprise suspension of a $ 37 billion stock offering by billionaire Jack Ma's Ant Group Co., making clear that no company can evade the government's regulation.
参考译文：这些规则草案是在亿万富翁马云的蚂蚁集团37亿美元股票发行被意外暂停之后出台的，明确表明没有公司能逃避政府监管。
定位线索：题干“suspension of Ant Group Co.'s stock offering”→答案句“surprise suspension of a $ 37 billion stock offering by billionaire Jack Ma's Ant Group Co.”；文中“no company can evade the government's regulation”对应选项C“All companies must be regulated by the government”（同义转述）。
解析：题干问蚂蚁集团股票发行暂停暗示了什么。答案句直接说明这次暂停“making clear that no company can evade the government's regulation”，即没有公司能逃避政府监管，与选项C“All companies must be regulated by the government”完全对应。选项A“All attempts to evade regulation are doomed to failure”程度过重，原文只说“no company can evade”，未说“doomed to failure”；选项B“monopolize sales”和选项D“created equal”在原文中均无依据，属于无中生有。

- A. They can no longer do business independent of tech giants.
- B. They are frequently denied access to tech giants' platforms.
- C. They have to change marketing strategies to keep customers.
- D. They no longer have the power to price their own products.
答案：A
答案句：Tech giants are increasingly assuming powerful positions in banking, finance, advertising, retail, and other markets that force smaller businesses to rely on their platforms to reach customers.
参考译文：科技巨头在银行、金融、广告、零售和其他市场中的地位日益强大，迫使小企业依赖它们的平台来接触客户。
定位线索：题干“smaller companies impacted by tech giants' business expansion”→答案句“force smaller businesses to rely on their platforms”；文中“rely on their platforms to reach customers”对应选项A“no longer do business independent of tech giants”（同义转述）。
解析：题干问小企业如何受到科技巨头业务扩张的影响。答案句明确指出科技巨头迫使小企业“rely on their platforms to reach customers”，即依赖其平台接触客户，与选项A“They can no longer do business independent of tech giants”（无法独立于科技巨头开展业务）完全对应。选项B“denied access”与原文“rely on”相反，属于偷换概念；选项C“change marketing strategies”和选项D“price their own products”在原文中均未提及，属于无中生有。

定位线索：题干“Americans generally think of social media companies”→答案句“the public in general have grown increasingly skeptical of social media companies”；文中“skeptical”对应选项C“untrustworthy”（同义转述）。
