Select the correct answer.

Which technology do social-news sharing sites use to provide updates to users?

A.
Flash
B.
RSS
C.
CSS3
D.
HTML5

B. RSS

The correct answer is B. RSS.

The correct answer is B. RSS.

Social-news sharing sites use RSS (Really Simple Syndication) technology to provide updates to users. RSS is a standardized web feed format that allows users to subscribe to website content, such as news articles or blog posts. When new content is published on the website, the RSS feed automatically sends the updates to the users' feed reader or aggregator.

To arrive at the answer, you could have eliminated options A, C, and D based on the fact that they are not primarily used for providing updates. Flash is a multimedia platform, CSS3 is a styling language, and HTML5 is a markup language for structuring web content. RSS, on the other hand, is specifically designed to deliver updates and syndicate content from websites to subscribers.
