Step-by-step explanation:
The announcement made by the museum representative during the press conference is an example of combining public relations with direct marketing.
Public relations is the practice of managing and maintaining a positive image and relationship with the public, which includes media relations and press conferences.
Direct marketing involves directly reaching out to specific individuals or households to promote a product, service, or cause, usually through mail, email, or other targeted channels.
