Problem: New Haven, Connecticut:

After the American Revolutionary War broke out in 1776, the Connecticut colonial government ordered the construction of Black Rock Fort (to be built on top of an older 17th-century fort) to protect the port of New Haven. In 1779, during the Battle of New Haven, British soldiers captured Black Rock Fort and burned the barracks to the ground. The fort was reconstructed in 1807 by the federal government (on orders from the Thomas Jefferson administration), and rechristened Fort Nathan Hale, after the Revolutionary War hero who had lived in New Haven. The cannons of Fort Nathan Hale were successful in defying British war ships during the War of 1812. In 1863, during the Civil War, a second Fort Hale was built next to the original, complete with bomb-resistant bunkers and a moat, to defend the city should a Southern raid against New Haven be launched. The United States Congress deeded the site to the state in 1921, and all three versions of the fort have been restored. The site is now listed on the National Register of Historic Places and receives thousands of visitors each year.

After which revolutionary war hero and New Haven native was Black Rock Fort rechristened upon reconstruction in 1807?
---
A: Nathan Hale


Problem: Environmental anthropology is a sub-specialty within the field of anthropology that takes an active role in examining the relationships between humans and their environment across space and time. The contemporary perspective of environmental anthropology, and arguably at least the backdrop, if not the focus of most of the ethnographies and cultural fieldworks of today, is political ecology. Many characterize this new perspective as more informed with culture, politics and power, globalization, localized issues, and more. The focus and data interpretation is often used for arguments for/against or creation of policy, and to prevent corporate exploitation and damage of land. Often, the observer has become an active part of the struggle either directly (organizing, participation) or indirectly (articles, documentaries, books, ethnographies). Such is the case with environmental justice advocate Melissa Checker and her relationship with the people of Hyde Park.
The data interpretation of environmental anthropology can be used to prevent what type of exploitation?

Answer: corporate


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Perhaps the first electric motors were simple electrostatic devices created by the Scottish monk Andrew Gordon in the 1740s. The theoretical principle behind production of mechanical force by the interactions of an electric current and a magnetic field, Ampère's force law, was discovered later by André-Marie Ampère in 1820. The conversion of electrical energy into mechanical energy by electromagnetic means was demonstrated by the British scientist Michael Faraday in 1821. A free-hanging wire was dipped into a pool of mercury, on which a permanent magnet (PM) was placed. When a current was passed through the wire, the wire rotated around the magnet, showing that the current gave rise to a close circular magnetic field around the wire. This motor is often demonstrated in physics experiments, brine substituting for toxic mercury. Though Barlow's wheel was an early refinement to this Faraday demonstration, these and similar homopolar motors were to remain unsuited to practical application until late in the century.
What toxic substance originally served the function of brine in primitive motors?
A: mercury


Context and question: Mass production of glass window panes in the early twentieth century caused a similar effect. In glass factories, molten glass was poured onto a large cooling table and allowed to spread. The resulting glass is thicker at the location of the pour, located at the center of the large sheet. These sheets were cut into smaller window panes with nonuniform thickness, typically with the location of the pour centered in one of the panes (known as "bull's-eyes") for decorative effect. Modern glass intended for windows is produced as float glass and is very uniform in thickness.
What was poured onto a large window pane?
Answer: unanswerable


Question: According to filings to the Canadian Radio-television and Telecommunications Commission (CRTC) by Thunder Bay Electronics (owner of CBC's Thunder Bay affiliate CKPR-DT) and Bell Media (owner of CBC affiliates CFTK-TV in Terrace and CJDC-TV in Dawson Creek),[citation needed] the CBC informed them that it will not extend its association with any of its private affiliates beyond August 31, 2011. Incidentally, that was also the date for analogue to digital transition in Canada. Given recent practice and the CBC's decision not to convert any retransmitters to digital, even in markets with populations in the hundreds in thousands, it is not expected that the CBC will open new transmitters to replace its affiliates, and indeed may pare back its existing transmitter network. However, in March 2011, CKPR announced that it had come to a programming agreement with the CBC, in which the station will continue to provide CBC programming in Thunder Bay for a period of five years. On March 16, 2012, Astral Media announced the sale of its assets to Bell Media, owners of CTV and CTV Two, for $3.38 billion with CFTK and CJDC included in the acquisition. Whether the stations will remain CBC affiliates or become owned-and-operated stations of CTV or CTV Two following the completion of the merger is undetermined.
Is there an answer to this question: The CBC cited not wanting to pay for the transition from analog to digital as it's reason for doing this?

Answer: unanswerable


Problem: Raleigh, North Carolina:

Raleigh is an early example in the United States of a planned city, chosen as the site of the state capital in 1788 and incorporated in 1792 as such. The city was originally laid out in a grid pattern with the North Carolina State Capitol in Union Square at the center. In the United States Civil War the city was spared from any significant battle, only falling in the closing days of the war, though it did not escape the economic hardships that plagued the rest of the American South during the Reconstruction Era. The twentieth century saw the opening of the Research Triangle Park in 1959, and with the jobs it created the region and city saw a large influx of population, making it one of the fastest growing communities in the United States by the early 21st century.

What century did Raleigh stop growing?
