Final answer:
Trailer parks are designed for stationary manufactured homes with access to utilities, contrasting with Bedouin nomadic tent camps that move frequently.
Step-by-step explanation:
The correct answer to the fill-in-the-blank question is A) Trailer. Trailer parks are tracts of land which contain sites with necessary utilities to allow five or more manufactured homes, occupied as single-family residences. Unlike the Bedouin pastoralists who live in camps with tents and move frequently to find fresh pastures, people in trailer parks live in mobile homes that are typically stationary and connected to utilities like water, sewer, and electricity. However, similar to the Bedouins, trailer park residents can move their homes if needed, but it is not done as frequently as the Bedouin's nomadic lifestyle.
