Final answer:
The subject of this question is Business and it is related to the built facilities in the business sector.
Step-by-step explanation:
Built facilities encompass various structures and complexes designed for specific purposes and contribute to the economic, political, and societal aspects of a community. These facilities include:
Shopping centers and retail complexes
Food and beverage establishments like restaurants and cafes
Convention and exhibition centers for events and trade shows
Hotels, resorts, and other lodging accommodations catering to travelers and tourists
Projects such as the Marina Bay Sands and the Harpal Music Hall Conference Centre serve as exemplars of built facilities that support tourism, community and regional development, and the provision of key services. Tourism, in particular, is significant as it is a growing sector that necessitates investment in infrastructure like airports and hotels, especially for island economies such as those in Melanesia. Moreover, the availability of facilities aligns with the notion that certain amenities, like sports teams or specialized boutiques, will only be found in larger cities or urban hierarchies, requiring strategic regional service centers.
