Explanation:

Most of the slaves held by West Africans in the late 1800s used to grow food crops. The chapter of slavery in America started in 1619 when 20 salves were brought by the The White Lion in Virgina.  

In the 17th and 18th centuries, black slaves worked basically on the tobacco, rice, and indigo plantations of the southern coast, from the Maryland and Chesippe Bay colonies to Georgia in the south.

when a country suffers, for example, a drought period, the market product is affected for a low offer, in this case, potatoes; the government has to tax to the households, which have to give more money for the potatoes which they consume, that situation make them consume substitute goods even through loans, it could increase the financial market movement and the inflationary phenomena, the business has to increase salaries in order to the employees could buy a more expensive food (potatoes) and in order to inflation tha business had to buy expensive supplies in the factor market, while the rest of the world have to gain more money to consume the same amount of potatoes.
