5、 The development of projection technology made it possible to project images on a large screen
6、 once films images could be projected， the cinema became a form of mass consumption
其中只有三个选项有本问题的关键词，本问题的关键词是 the technology of cinema.
二）细节信息排除法
总结题是对对文章的高度概括所以细节的出现犯了以偏概全的错误，如中文例子中的2、丽丽扶一个盲人过马路。 这是一个具体的事实细节，我们要绕过例子看总结。所以在排除它。
