Which type of message would NOT typically require a response?

Informative announcements typically serve the purpose of delivering information to an audience without expecting a response. They are usually one-way communications meant to inform individuals about events, updates, or news. For example, an announcement regarding a course schedule change or an upcoming campus event conveys essential information and does not inherently require the recipient to reply or take action.

In contrast, questions posed by peers and direct requests are explicitly designed to elicit a response or feedback. Personal messages can also invite interactions, although the expecting response may vary based on the context and relationship between the individuals involved. The lack of an expectation for a reply in informative announcements sets them apart from the other types of messages mentioned.
