In winter, the Piedmont is colder than the coast, with temperatures usually averaging in the upper 40s–lower 50s °F (8–12 °C) during the day and often dropping below the freezing point at night. The region averages around 3–5 in (8–13 cm) of snowfall annually in the Charlotte area, and slightly more north toward the Virginia border. The Piedmont is especially notorious for sleet and freezing rain. Freezing rain can be heavy enough to snarl traffic and break down trees and power lines. Annual precipitation and humidity are lower in the Piedmont than in the mountains or the coast, but even at its lowest, the average is 40 in (1,020 mm) per year.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What do the temperatures often drop to at night in the piedmont region in the winter?
Ah, so.. below the freezing point

Popper played a vital role in establishing the philosophy of science as a vigorous, autonomous discipline within philosophy, through his own prolific and influential works, and also through his influence on his own contemporaries and students. Popper founded in 1946 the Department of Philosophy, Logic and Scientific Method at the London School of Economics and there lectured and influenced both Imre Lakatos and Paul Feyerabend, two of the foremost philosophers of science in the next generation of philosophy of science. (Lakatos significantly modified Popper's position,:1 and Feyerabend repudiated it entirely, but the work of both is deeply influenced by Popper and engaged with many of the problems that Popper set.)
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): When was the Department of Philosophy, Logic and Scientific Method at the London School of Economics disbanded?
Ah, so.. unanswerable
