Refer to the passage.
"What really enables the colonists to make both ends meet is the crops they have the right to raise on their own account, sometimes on allotments reserved for the purpose set apart from the coffee, and sometimes between the rows of the coffee-trees. They often think more of the clauses in their contract which relate to these crops than to those which determine their wages in currency. A planter told me that he had learned that a party of colonists intended to leave him after the harvest. We met some of them on the road, and I questioned them.
‘Is it true that are engaged to work on Senhor B—’s fazenda for the coming year?’
‘Yes.’
‘What reason have you for changing your fazenda? Will you be better paid there? Don’t you get over £6 a thousand trees here?’
‘Yes.’
‘How much do they offer you over there?’
‘Only £4.’
‘Then why do you go?’
‘Because there we can plant our maize among the coffee.’
The culture of coffee is thus combined with that of alimentary crops. Almost all the world over the important industrial crops have to make room in the neighborhood for food crops.”
Excerpt from Brazil by Pierre Denis, ca. 1911, describing large Brazilian coffee plantations known as fazendas
Which of the following best compares how environmental conditions in Brazilian coffee plantations and American tobacco plantations contributed to migration patterns?
Brazilian and American plantations in tropical regions discouraged the growth of food crops and limited the numbers of laborers who migrated there.
Both regions required the importation of immense numbers of laborers to produce in-demand cash crops that could only be grown in warm-weather climates.
Depleted soil conditions caused both regions to shift from cash-crop production to subsistence agriculture, decreasing the number of workers moving to the respective areas.
Laborers from outside the respective areas were encouraged to immigrate to help produce additional food crops in hopes of maximizing economic production prior to colonizing new territories with richer soil.
