Reasons for poverty in brazil include all of these factors except a lack of affordable and available farmland a scarcity of natural resources poor soil and climate in the northeast a lack of well-paying jobs in the cities

The answer is - a scarcity of natural resources.

This is not a reason at all for poverty in Brazil. Brazil is a country that has abundance of natural resources, oil, gas, timber, water, minerals, you name it. The problem is the way in which this resources are used, not the lack of them. The way of usage of them is suitable for the rich who take the biggest piece of the 'pie', while the poor population barely sees any benefit from them.
