本题考查对文本中所使用论证技巧的识别。解题思路是分析文本内容，判断其运用了哪种常见的论证技巧。

• 首先明确各个选项所代表的论证技巧含义：
  • 选项A“details”指细节，通常是对事物具体特征、情况等的描述。
  • 选项B“personal experiences and observations”指个人经历和观察，是基于个人亲身经历或所见所闻来阐述观点。
  • 选项C“statistics”指统计数据，是通过具体的数字来呈现信息。
  • 选项D“surveys”指调查，一般是通过问卷、访谈访问等方式收集信息。
• 然后看给定的文本“Public cultural services in poor areas have been improved. By the end of 2020, 99.48% of villages in 22 provinces and equivalent administrative units in central and western China had seen their own cultural centers completed.”，文本中出现了“99.48%”“22 provinces”等具体的数字，这些数字是用于说明贫困地区公共文化服务改善情况的统计数据。
• 所以该文本运用的论证技巧是“statistics”。
