Final answer:
Increases in global trade, migration, and technology stress the existence of a globally shared culture, leading to a blending of cultures and the emergence of a global monoculture.
Step-by-step explanation:
Increases in global trade, migration, and technology stress the existence of a globally shared culture. These forces of change have made the world a smaller place, allowing for more communication, travel, and trade between different societies. As a result, people are able to share movies, music, information, and even study with others from different parts of the world. This leads to a blending of cultures and the emergence of a global monoculture.
