Answer:
(A) The Little Ice Age caused shortages of food and reduced the amount of agricultural surplus available for trade.
Explanation:
The Little Ice Age lasted from the thirteenth century to the early nineteenth century, and it consisted of a period of generally colder temperatures compared with the previous period: the Medieval Warm Period.
The Little Ice Age made life more difficult for Europeans, specially in Northern Europe. For example, it caused the Norse colonies in Greenland to died out, and the people of Iceland almost died out as well, suffering from frequent famines and poverty. In Britain, for example, a few vines could be cultivated in the Southern half of the island, but this ended once the Little Ice Age started.
