__________ ____________ shall be given if part of the building is to be used for a purpose other than ________ _______.

The correct choice indicates that "special authorization" is necessary when part of a building is designated for a purpose other than "healthcare." In the context of nursing home operations and relevant regulations, any change in the use of space within the facility—especially if it diverges from healthcare practices—requires an official process to ensure compliance with health and safety standards and to protect the well-being of residents. Special authorization serves as a safeguard by making sure that any new use aligns with legal requirements and does not compromise the care environment. This emphasizes the importance of maintaining regulatory adherence when modifications occur in a facility's designated use, reinforcing the need for oversight in how spaces are utilized within healthcare environments.
