Question:
In Britain, free trade became a central principle practiced by the repeal of the Corn Laws in 1846. Large-scale agitation was sponsored by the Anti-Corn Law League. Under the Treaty of Nanking, China opened five treaty ports to world trade in 1843. The first free trade agreement, the Cobden-Chevalier Treaty, was put in place in 1860 between Britain and France, which led to successive agreements between other countries in Europe. Many classical liberals, especially in 19th and early 20th century Britain and in the United States for much of the 20th century , believed that free trade promoted peace. Woodrow Wilson included free-trade rhetoric in his "Fourteen Points" speech of 1918:

What treaty led to the opening of Chinese ports to other countries?

Answer:
Treaty of Nanking

Question:
With regulations in place and DDT banned, the eagle population rebounded. The bald eagle can be found in growing concentrations throughout the United States and Canada, particularly near large bodies of water. In the early 1980s, the estimated total population was 100,000 individuals, with 110,000115,000 by 1992; the U.S. state with the largest resident population is Alaska, with about 40,00050,000, with the next highest population the Provinces and territories of Canada of British Columbia with 20,00030,000 in 1992. Obtaining a precise count of bald eagles population is extremely difficult. The most recent data submitted by individual states was in 2006, when 9789 breeding pairs were reported. For some time, the stronghold breeding population of bald eagles in the lower 48 states was in Florida, where over a thousand pairs have held on while populations in other states were significantly reduced by DDT use. Today, the Contiguous United States with the largest number of breeding pairs of eagles is Minnesota with an estimated 1,312 pairs, surpassing Floridas most recent count of 1,166 pairs. 23, or nearly half, of the 48 contiguous states now have at least 100 breeding pairs of bald eagles. In Washington State, there were only 105 occupied nests in 1980. That number increased by about 30 per year, so that by 2005 there were 840 occupied nests. 2005 was the last year that the Washington Department of Fish and Wildlife counted occupied nests. Further population increases in Washington may be limited by the availability of late winter food, particularly salmon.

How many breeding pairs of bald eagles are not in Minnesota or Florida?

Answer:
7311

Question:
The 1970s saw a number of new models added to the Buick lineup including the Estate Wagon as its own model in 1970, Buick Centurion in 1971, Buick Apollo in 1973, and Buick Skyhawk in 1975. 1975 also saw the first appearance of the "Buick Park Avenue" nameplate for Buick as a trim/option package on the Electra 225 Limited. A Buick Century paced the Indianapolis 500 race not once but twice in the mid 1970s. For 1976, Buick began selling rebadged Isuzu Geminis as Opels to replace the Opel Kadett models it had previously marketed. The following year, Electra 225 and LeSabre were redesigned and downsized and the Buick brand saw its best model year sales to date with 773,313 vehicles sold. 1978 marked Buicks 75th anniversary and welcomed a redesigned Century as well as a redesigned Regal coupe which was now available with a turbocharged Buick V6 engine engine. Buick model year sales broke another record in 1978 with 795,316 vehicles sold. For 1979, the Riviera was redesigned; Riviera S-Type was named Motor Trend Car of the Year.

Which model was introduced first, the Apollo or the Skyhawk?

Answer:
Apollo

Question:
During the 1960s, the UNC campus was the location of significant political protest. Prior to the passage of the Civil Rights Act of 1964, protests about local racial segregation which began quietly in Franklin Street restaurants led to mass demonstrations and disturbance. The climate of civil unrest prompted the 1963 Speaker Ban Law prohibiting speeches by communists on state campuses in North Carolina. The law was immediately criticized by University Chancellor William Brantley Aycock and University President William Friday, but was not reviewed by the North Carolina General Assembly until 1965. Small amendments to allow "infrequent" visits failed to placate the student body, especially when the university's board of trustees overruled new Chancellor Paul Frederick Sharp's decision to allow speaking invitations to Marxist speaker Herbert Aptheker and civil liberties activist Frank Wilkinson; however, the two speakers came to Chapel Hill anyway. Wilkinson spoke off campus, while more than 1,500 students viewed Aptheker's speech across a low campus wall at the edge of campus, christened "Dan Moore's Wall" by The Daily Tar Heel for Governor Dan K. Moore. A group of UNC students along with Aptheker and Williamson filed a lawsuit in U.S. federal court, and on February 20, 1968, the Speaker Ban Law was struck down. In 1968, only a year after its schools became fully integrated, Chapel Hill became the first predominantly white municipality in the country to elect an African American mayor, Howard Lee. Lee served from 1969 until 1975 and, among other things, helped establish Chapel Hill Transit, the town's bus system.

How many total years did Howard Lee serve as Mayor?

Answer:
6
