Final answer:
A sports complex does not necessarily need to have both a stadium and an arena; it varies in size and may include different sports facilities based on the level of play and the requirements of the community.
Step-by-step explanation:
To answer your question, having a stadium and an arena is not a prerequisite for a facility to be classified as a sports complex. The term sports complex generally refers to a facility that houses multiple sports fields or spaces and could include stadiums, arenas, fields, and courts, but the presence of a stadium and an arena is not mandatory. Sports complexes can vary greatly in size and may serve a range of sports activities.
In many cases, sports like soccer, cricket, and basketball can be played in open spaces or makeshift play areas without the need for full-sized pitches or courts, especially at the amateur or children's level. For instance, local communities can use vacant lots, streets, and small parks for recreational sports without the significant investment that professional-level facilities demand. Moreover, professional sports teams often prompt the construction of sports stadiums as part of economic development strategies, which suggests that a sports complex could evolve and expand as the needs of the community or professional teams dictate.
