Answer:
Consider the following explanation.
Step-by-step explanation:
According to the law of one price, identical goods 
sold IN DIFFERENT LOCATIONS must sell for the same 
price, except for costs associated with MOVEMENT BETWEEN LOCATIONS. 
Those costs reflect TRADE BARRIERS and the cost of shipping. 
According to the law of one price, if the price of a good 
in one location does not match the price of the same good in 
a different location, sellers will increase supply 
in the location where the good is MORE EXPENSIVE 
until prices in both locations are equal.
