Please read the following:
Between A.D.900 and 1300, the earth warmed by some three degrees. Scholars refer to that period—one of the most favorable in human history—as the Medical Climate Optimum.
Food production surged. Key agricultural regions experienced fewer floods and droughts. Death rates declined in many places, partly because of the decrease in hunger and partly because people spent less time huddled in damp, smoke-filled hovels that helped spread tuberculosis and other infectious diseases.
Prosperity stimulated an outpouring of creativity—in architecture, art and practical invention.
Trade flourished, in part because there were fewer storms at sea.
On the whole, in the period of the Medieval Climate Optimum, ________ under the influence of global warming.
(a) culture, trade and farming got fully developed
(b) food production was well controlled
(c) nature disasters like floods and droughts came more often
(d) death rate declined all over the world
The key is A. But D is also possible. Is that right?
Looking forward to hearing from you.
Thank you in advance.
