Which aspect could negatively impact a page's quality rating?

The choice indicating that advertisements blended with Main Content could negatively impact a page's quality rating is correct because it highlights how user experience is affected by the way in which ads are presented. When advertisements are seamlessly integrated into the main body of content, it can confuse users and lead to a perception that the page prioritizes revenue generation over providing valuable information. This blending can detract from the overall usability and credibility of the content, as users may find it difficult to distinguish between the main content and the ads. High-quality pages typically maintain clear boundaries between promotional content and informational content to ensure that users can easily access the information they are seeking without distractions or confusions.
