I don't think anyone will answer this but just devote one paragraph to talking about how supply and demand dictate prices, and another paragraph to how international trade fuels economic growth.

Answer:
The Correct Answer is B
Explanation:
Medicine was a central part of medieval Islamic culture. Responding to circumstances of time and place/location, Islamic physicians and scholars developed a large and complex medical literature exploring, analyzing, and synthesizing the theory and practice of medicine. Islamic medicine was initially built on tradition, chiefly the theoretical and practical knowledge developed in Arabia and was known at Muhammad's time, ancient Hellenistic medicine such as Unani, ancient Indian medicine such as Ayurveda, and the ancient Iranian Medicine of the Academy of Gundishapur. The works of ancient Greek and Roman physicians Hippocrates, Galen and Dioscorides also had a lasting impact on Islamic medicine. Ophthalmology has been described as the most successful branch of medicine researched at the time, with the works of Ibn al-Haytham remaining an authority in the field until early modern times.
Maybe while we wait for the questioner to provide the options, we can do a little general discussion here about what it means to use a primary source. Primary sources are things that come from persons directly involved in the events or lives being studied. So, any diary entries or letters of George Washington himself would count as primary sources. So would any official proclamations or letters or government documents that came from Washington's pen as president. Or the testimony of contemporaries of his who lived or worked with him would also count as primary source accounts.
So if you're looking for a historian's use of primary sources, look for the ways in which he's using historical material directly connected to the life of the person being studied. In fact, if you were able to look at a set of the false teeth George Washington wore, that would be a primary source too. They have a set at the Mount Vernon home/museum. And by looking at those actual dentures, you'd see they weren't made out of wood like the old (false) story says!
