Which one of the following features is in Twitter's Live Events but not Twitter's Live Broadcasts?

Twitter Live Events are curated experiences that can include multiple video sources, such as a Video Carousel displaying various live streams or clips related to the event. This feature allows for a richer, multi-faceted viewing experience. Live Broadcasts, on the other hand, typically focus on a single live video stream from a specific publisher. Both Live Events and Live Broadcasts can incorporate Conversation features (like replies and retweets) around the content. Virtual live stream testing and support from the Publisher Help team is a service offered to publishers for both Live Events and Live Broadcasts to ensure technical quality, not a user-facing feature differentiating the two.
