What term refers to a list that contains a class of objects, often found in social media?

The correct answer is a term that refers to a collection of content presented to users, often in a dynamic and real-time manner. In the context of social media, a "feed" is a continuous stream of posts from users' connections or sources that they follow. This feed can include various types of media such as text updates, images, videos, and shared links, providing users with an ongoing glimpse into the activities and thoughts of others within their network.

While "post," "update," and "story" are all related to social media content, they refer to specific types of interactions or content pieces. A "post" typically means a single entry made by a user, an "update" can imply a change or new information about something a user shares, and a "story" usually refers to a temporary content format that is available for a limited time. Therefore, "feed" accurately describes the overarching concept of a list or collection of these various user-generated entries.
