____________ can be defined as any fabric, banner, or bunting containing distinctive colors, patterns or symbols, used as a symbol of a government, political subdivision, or other entity.

The definition provided in the question aligns perfectly with the characteristics of flags. Flags are indeed made from fabric and often display distinctive colors, patterns, or symbols that represent various entities such as governments, political subdivisions, or organizations. The use of flags is rooted in symbolism and representation, making them easily identifiable as a form of communication and identity.

In contrast, projecting signs, pole signs, and wall signs refer to types of signage primarily used for advertising or informational purposes. These do not carry the same symbolic meaning associated with flags, which serve a specific role in representing entities at a more symbolic and cultural level. Thus, flags are the correct choice as they fit the description given in the question.
