Answer:
it can still gain from international trade in that commodity, by getting it at a lower opportunity cost than if it produced it domestically.
Explanation:
A country has comparative disadvantage in production if it produces at a higher opportunity cost when compared to other countries.
The country with a  comparative disadvantage can gain from trade by trading the good with a country that has  comparative advantage in the production of that good. i.e. the country produces at a lower opportunity cost
For example, country A produces 10kg of beans and 5kg of rice. Country B produces 5kg of beans and 10kg of rice.  
for country A,  
opportunity cost of producing beans = 5/10 = 0.5
opportunity cost of producing rice = 10/5 = 2
for country B,  
opportunity cost of producing rice = 5/10 = 0.5
opportunity cost of producing beans = 10/5 = 2
Country B has a comparative disadvantage in the production of beans and country A has a comparative disadvantage in the production of rice
Country B should buy beans from A and A should buy rice from B
