　　【解析】

　　31. 根据题干内容定位到第一段，并且 “Facebook”和“Whats App” 可以精确定位到第一段的句中的“to acquire the Whats App messaging service”以及“What Whats App offered Facebook was an intricate and finely detailed web of its users’ friendships and social lives”，因此，答案可以定位到B 选项，user information。

　　32. 根据题干定位到该段首句，it broken the promise almost as soon as the deal went through， 以及在下一句中even引导的句中“the knowledge of who sent them and to whom was enormously revealing and still could be”，我们可以的看到将电话号码与Facebook身份验证连接可能会对用户造成威胁，因此答案为“pose a risk to Facebook users”。

　　33. 根据题干内容定位到第三段Competition law appears to be the only way to address these imbalances of power. But, it is clumsy. For one thing, it is very slow compared to the pace of change within the digital economy. 可知it 指代的是competition law，而且竞争法太慢了，赶不上数字经济的步伐。 而D选项cannot keep pace with the changing market 正好与本句是同义替换，因此正确选项是D选项。

　　34. 根据题干定位到原文第三段倒数第2句，The users of their services are not their customers. 可知他们服务的用户不是他们的客户，而A选项they are not defined as customers意为用户不被定义为顾客，所以正确选项是A选项。

　　35. 根据题干定位到原文第四段Just as some ants farm the bugs called aphids for the honeydew they produce when they feed, so Google farms us for the data that our digital lives yield. 而D选项the relationship between digital giants and their users 意为数字巨头和他们的用户之间的关系，因此D选项是正确选项。
