Answer:
A
Step-by-step explanation for why it's A:
The earth has become increasingly interconnected over recent times which has resulted in increased connection as well as cultural exchange amongst individuals.
This has allowed people to have access to new cultures,beliefs and ideas that were otherwise unavailable in their place of inhabitance.
Hence, Japanese music has become a lot more prevalent in the western world than it was say 60 years ago in a similar way American music has become more prevalent in Europe.
Software such as the internet have rapidly sped up globalisation and have resulted in remote accesibility to platforms such as social media that have made this cultural exchange boom in recent times possible.
Why it isn't the other options:
<em> </em><em> </em>It could not be (b) as no forms of trading of commodities or other financial instruments are exchanged during the sharing of musical culture.
It could not be (c) as the spread of foreign culture within an area does not affect the manufacturing of goods and how they are sold between the involved countries.
It could not be (d) as certain procedures relating to the governance of a country( for instance in America)as well as political ideologies did not flourish( in a country say Japan) due to foreign musical acquisition.
Hope this helps!
