In some countries, national planners have attempted to address the problems resulting from increasing urbanization by reducing migration from rural areas.
Assertion
National leaders could solve the problems resulting from migration from rural to urban areas by trading goods or services produced by their urban populations in order to obtain agricultural products that used to be produced domestically (in rural areas).
Evaluate
This isn't called an argument or reasoning, so we don't need to be looking for a Conclusion and Premise.
The assertion seems to make a few assumptions: - one of the problems (if not the only one) with people migrating from rural to urban is that we're worried that once they leave the rural area, we'll no longer have the agricultural products that used to be made there
- these soon-to-be-missing agricultural products are available on world markets
- our urban places produce enough desirable goods that other countries would want that it would feasible to entice other countries into trading with us
Goal
Let's look for an answer affirming something this plan is assuming, ruling out a potential objection to the plan (alternate plans aren't objections ... it only weakens to argue that this play couldn't do it), or just providing a new fact that makes it seem like this plan could work.
