Answer: C. education, technology, transportation
This option encompasses the main factors that have led to increased globalization. Education has been one of the most important factors, because as people become more educated, they become more interested in other parts of the world. They also become more tolerant, which facilitates cultural exchanges. Education also gives many people the chance to visit other regions of the world in the form of study abroad programs.
Technology has linked the world in ways that had never been experienced before. News can be known anywhere in the world within minutes. Family members that live in different areas of the world can communicate with each other instantly. Moreover, certain technology, such as social media and cell phones, are popular all over the world, which leads to an homogeneity that did not exist before.
Finally, transportation has allowed people to travel far away cheaply, which has in turn increased interest, understanding and tolerance of other cultures.
