Because of the Great Lakes, Midwestern farmers have access to: all of the United States markets
markets all around the world
markets on the the Atlantic coast
markets on the Pacific coast

markets all around the world

Explanation:

The Great Lakes provides access to Midwestern farmers to markets all over the world because each lake is linked and eventually empties into the Atlantic ocean. Midwestern farmers are therefore able to ship their goods via the great lakes, to the Atlantic, to anywhere in the world.

This enabled the growth of heavy industry and other economic sectors in the area as the people took advantage of the logistical advantages offered by the Great Lakes.

swahili is an extremely rich and complex civilization, a set of ethnic groups articulated by a language and a series of cultural elements that fuse the african traditions, islam and indian culture. this growth was largely a result of the indian ocean trading network that brought in not just man-made riches, but also religious ideas, specifically islam, which had a significant impact on the local culture. furthermore, the development of the swahili language gave a common cultural unity to the people.
