NAFTA was created for the purpose of eliminating trade barriers between member nations.
The correct answer is - I, II, and III.
By the obscure information about the Region A and the size of the farmlands in it, we can roughly conclude that the Region A has a topography which is not allowing for larger farms to be formed, the people in that region are probably not financially very powerful, and that the farming is not heavily mechanized.
Very often the topography of a region can dictate the size of the farmlands, as there's only certain places that are suitable for farming. So if the region is mostly hilly and has mountains, the farmlands can be very big.
Another factor that can be crucial in determining the size of the farmlands is the financial power of the people. If the people can not afford to buy bigger land areas, than the farmlands will be relatively small.
If the farmlands are not big, than they can be worked with less mechanization, with the human and animal power being in the spotlight, but also, if the farmers are not financially strong enough, they will not be able to buy the needed mechanization.
We kinda need to see and read the section to understand what it is
