Which examples describe the results of globalization? CHOOSE ALL THAT ARE CORRECT.
velikii [3]
The opinion may varies on this question, here are my point of views.

The correct answer would be:
A) spread of innovations
B) cultural blending
C) damage to some cultures

Let's look into them one by one:

A) spread of innovations

- As the technological skills on different areas spread to different countries, people are able to learn and create based on the new knowledge hence enhancing innovations across the world.

(- However,some might held a different opinion as the innovations are concentrated in powerful nations but not the third world countriedls. But what I believe is that under the spread of information, third world countries have chances for innovations as well therefore supporting this claim.)

B) cultural blending

- Under globalization, it is easier for people to travel around the world, bring their own culture and influence to a foreign place, resulting in the blend of culture. For example, you can see many international brands across the globe even in Asia, while you can find China town and production of Asia in places like Europe and America.

C) damage to some cultures

- This is also true. As globalization prevails, some cultures are considered less important as the living mode of people has changed. Languages for example, inder the influence of international language such as English, some minorities dialect are disappearing or the use is decreasing rapidly.

D) increase in death rate

- This is very unlikely to happen. As globalization brings the technology around, the medical advancements are also able to be brought to different place. For instance, the use of xray, or even cancer treatment, are spreaded. This has undoubtedly helped expanding the life span of people.

Therefore the correct answer would be:
A) spread of innovations
B) cultural blending
C) damage to some cultures
