I agree with this statement because when a country isolates themselves they don't really know anything about other countries. How can you trust people you don't know. Trade is a way to spread religion and culture! China spreads it's culture with silk! Japan spreads its culture with food. Korea spreads its culture with its music. Everyone has something different to contribute in trade and it gets put into different countries like a melting pot!
A. seems the most likely because rest are absurd. Increase in profits = less money to spend which = more money to spend on ads or add more goods to make at the factory
