A. Numbers of measurements

B. Dates

C. percentages

题目解答

答案

A. Numbers of measurements

解析

本题考查对统计类型的识别能力，需要区分测量数值、日期和百分比三种类型。解题关键在于定位句子中的具体数据形式：

  • 测量数值通常包含具体数量（如吨、公顷、人口数）；
  • 日期涉及时间点或时间段；
  • 百分比需明确出现“%”或“percent”。

句子分析

  1. 第一句未出现具体数据；
  2. 第二句中的“half”是比例，但未用百分比形式；
  3. 第三句明确出现“two tons per hectare”和“400-500 million”，均为具体数值。

选项排除

  • B（日期）：文中无时间相关描述；
  • C（百分比）：“half”非标准百分比形式；
  • A（测量数值）：直接包含“吨”“公顷”“百万人口”等度量单位。
