Topic 1: Increasing travels between countries enable people to learn different cultures or to increase tension between people from different countries

self-contained 
economy. 
Scarcity 
of resource or lack of technology might 
disable a country from producing crops to feed its population, but it cannot be taken as an excuse for 
relying heavily on imports. Government funding in scientific research can make it possible to achieve a 
breakthrough and increase 
the yield, 
thereby resolving food supply crisis. 
Countries  are  therefore  advised  to  promote  international  trade  and  to  develop  their  own
 
industries 
simultaneously. 
Positive  attitudes  toward  importing  goods  from  other  countries  demonstrate  a 
government's 
stance 
on the international trade, although the government should also prevent itself from 
relying on imported goods.
