Input: Article: In winter, the Piedmont is colder than the coast, with temperatures usually averaging in the upper 40slower 50s F (812 C) during the day and often dropping below the freezing point at night. The region averages around 35 in (813 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.

Now answer this question: What do the temperatures often drop to at night in the piedmont region in the winter?

Output: below the freezing point

Article: Over time, Roman architecture was modified as their urban requirements changed, and the civil engineering and building construction technology became developed and refined. The Roman concrete has remained a riddle, and even after more than 2,000 years some Roman structures still stand magnificently. The architectural style of the capital city was emulated by other urban centers under Roman control and influence. Roman cities were well planned, efficiently managed and neatly maintained.[citation needed]

Question: Do any Roman structures still exist in our time?
Ans: even after more than 2,000 years some Roman structures still stand magnificently

Here is a question about this article: There is an extensive network of caves, including Wookey Hole, underground rivers, and gorges, including the Cheddar Gorge and Ebbor Gorge. The county has many rivers, including the Axe, Brue, Cary, Parrett, Sheppey, Tone and Yeo. These both feed and drain the flat levels and moors of mid and west Somerset. In the north of the county the River Chew flows into the Bristol Avon. The Parrett is tidal almost to Langport, where there is evidence of two Roman wharfs. At the same site during the reign of King Charles I, river tolls were levied on boats to pay for the maintenance of the bridge.
What is the answer to this question: What did King charles levy on river boats
****
So... King Charles I, river tolls were levied on boats to pay for the maintenance of the bridge.

The problem: Answer a question about this article:
In the early 20th century, Carl von Voit and Max Rubner independently measured caloric energy expenditure in different species of animals, applying principles of physics in nutrition. In 1906, Edith G. Willcock and Frederick Hopkins showed that the amino acid tryptophan aids the well-being of mice but it did not assure their growth. In the middle of twelve years of attempts to isolate them, Hopkins said in a 1906 lecture that "unsuspected dietetic factors," other than calories, protein, and minerals, are needed to prevent deficiency diseases. In 1907, Stephen M. Babcock and Edwin B. Hart conducted the single-grain experiment, which took nearly four years to complete.
Which experiment related to diet was conducted that required four years to complete?
****
The answer: single-grain experiment

Problem: Please answer a question about the following article about North Carolina:

Question: Read this and answer the question

The U.S. dollar was created by the Constitution and defined by the Coinage Act of 1792. It specified a "dollar" to be based in the Spanish milled dollar and of 371 grains and 4 sixteenths part of a grain of pure or 416 grains (27.0 g) of standard silver and an "eagle" to be 247 and 4 eighths of a grain or 270 grains (17 g) of gold (again depending on purity). The choice of the value 371 grains arose from Alexander Hamilton's decision to base the new American unit on the average weight of a selection of worn Spanish dollars. Hamilton got the treasury to weigh a sample of Spanish dollars and the average weight came out to be 371 grains. A new Spanish dollar was usually about 377 grains in weight, and so the new U.S. dollar was at a slight discount in relation to the Spanish dollar.

What was the average weight of a new Spanish dollar in terms of grains?
Answer:
377
