As in the rest of the former Confederacy, North Carolina had become a one-party state, dominated by the Democratic Party. Impoverished by the Civil War, the state continued with an economy based on tobacco, cotton and agriculture. Towns and cities remained few in the east. A major industrial base emerged in the late 19th century in the western counties of the Piedmont, based on cotton mills established at the fall line. Railroads were built to connect the new industrializing cities. The state was the site of the first successful controlled, powered and sustained heavier-than-air flight, by the Wright brothers, near Kitty Hawk on December 17, 1903. In the first half of the 20th century, many African Americans left the state to go North for better opportunities, in the Great Migration. Their departure changed the demographic characteristics of many areas.
What was the economy of North Carolina based on after the confederacy?
tobacco, cotton and agriculture

Input: Bird migration
Records of bird migration were made as much as 3,000 years ago by the Ancient Greek writers Hesiod, Homer, Herodotus and Aristotle. The Bible also notes migrations, as in the Book of Job (39:26), where the inquiry is made: "Is it by your insight that the hawk hovers, spreads its wings southward?" The author of Jeremiah (8:7) wrote: "Even the stork in the heavens knows its seasons, and the turtle dove, the swift and the crane keep the time of their arrival."

Who recorded early records of migration?
Output: Ancient Greek writers

Input: Article: The Sardinian language is considered to be its own Romance language family, separate not only from standard Italian but also the wider Italo-Dalmatian family, and it includes the Campidanese Sardinian and Logudorese Sardinian variants. However, Gallurese, Sassarese, and Corsican are also spoken in Sardinia, and these languages are considered closely related or derived from the Italian Tuscan language and thus are Italo-Dalmatian languages. Furthermore, the Gallo-Romance language of Ligurian and the Catalan Algherese dialect are also spoken in Sardinia.

Now answer this question: What language family does Ligurian belong to?

Output: Gallo-Romance

Article: Royal assent is the method by which a country's constitutional monarch (possibly through a delegated official) formally approves an act of that nation's parliament, thus making it a law or letting it be promulgated as law. In the vast majority of contemporary monarchies, this act is considered to be little more than a formality; even in those nations which still permit their ruler to withhold the royal assent (such as the United Kingdom, Norway, and Liechtenstein), the monarch almost never does so, save in a dire political emergency or upon the advice of their government. While the power to withhold royal assent was once exercised often in European monarchies, it is exceedingly rare in the modern, democratic political atmosphere that has developed there since the 18th century.

Question: Is usage of the royal assent frequent or rare in today's societies?
Ans: exceedingly rare

Here is a question about this article: The junction forward voltage is the voltage applied to the emitterbase junction of a BJT in order to make the base conduct a specified current. The current increases exponentially as the junction forward voltage is increased. The values given in the table are typical for a current of 1 mA (the same values apply to semiconductor diodes). The lower the junction forward voltage the better, as this means that less power is required to "drive" the transistor. The junction forward voltage for a given current decreases with increase in temperature. For a typical silicon junction the change is 2.1 mV/C. In some circuits special compensating elements (sensistors) must be used to compensate for such changes.
What is the answer to this question: Why is the ideal junction forward voltage lower?
****
So... less power is required to "drive" the transistor

Article: Gallaeci lived in castros. These were usually annular forts, with one or more concentric earthen or stony walls, with a trench in front of each one. They were frequently located at hills, or in seashore cliffs and peninsulas. Some well known castros can be found, in the seashore, at Fazouro, Santa Tegra, Barona and O Neixon, and inland at San Cibrao de Las, Borneiro, Castromao, and Viladonga. Some other distinctive features, such as temples, baths, reservoirs, warrior statues and decorative carvings have been found associated to this culture, together with rich gold and metalworking traditions.

Question: Where were these forts commonly built?
Ans:
hills
