下面哪种报告会按照用户使用的设备类型，重点标识用户在商品详情页面上的行为？

The "Pages and screens" report is correct because it provides data on how users interact with specific pages or screens, including product detail pages. You can then segment this data by device type to see behavior patterns. The "Tech details" report focuses on the technologies used (browser, OS, device model) but doesn't directly show page-specific behavior. The "Events" report tracks user interactions like clicks or video plays, which can occur on product pages, but it doesn't inherently focus on the page itself as the primary dimension. The "User acquisition" report focuses on how users arrive at your site, not their behavior on specific pages once they are there.
