Problem: Other Fortune 500 companies, while not headquartered in the area, do have a major presence. These include SunTrust Bank (based in Atlanta), Capital One Financial Corporation (officially based in McLean, Virginia, but founded in Richmond with its operations center and most employees in the Richmond area), and the medical and pharmaceutical giant McKesson (based in San Francisco). Capital One and Altria company's Philip Morris USA are two of the largest private Richmond-area employers. DuPont maintains a production facility in South Richmond known as the Spruance Plant. UPS Freight, the less-than-truckload division of UPS and formerly known as Overnite Transportation, has its corporate headquarters in Richmond.
What city is the headquarters of McKesson located in?
The answer is the following: San Francisco

Problem: The Thuringian Realm existed until 531 and later, the Landgraviate of Thuringia was the largest state in the region, persisting between 1131 and 1247. Afterwards there was no state named Thuringia, nevertheless the term commonly described the region between the Harz mountains in the north, the Weiße Elster river in the east, the Franconian Forest in the south and the Werra river in the west. After the Treaty of Leipzig, Thuringia had its own dynasty again, the Ernestine Wettins. Their various lands formed the Free State of Thuringia, founded in 1920, together with some other small principalities. The Prussian territories around Erfurt, Mühlhausen and Nordhausen joined Thuringia in 1945.
How long did the Thuringian realm exist?
The answer is the following: until 531 and later

Problem: When revolutionary France declared war on Great Britain in 1793, the United States sought to remain neutral, but the Jay Treaty, which was favorable to Great Britain, angered the French government, which viewed it as a violation of the 1778 Treaty of Alliance. French privateers began to seize U.S. vessels, which led to an undeclared "Quasi-War" between the two nations. Fought at sea from 1798 to 1800, the United States won a string of victories in the Caribbean. George Washington was called out of retirement to head a "provisional army" in case of invasion by France, but President John Adams managed to negotiate a truce, in which France agreed to terminate the prior alliance and cease its attacks.
When was the Treaty of Alliance with France signed? 
The answer is the following: 1778

Problem: Endemic species can be threatened with extinction through the process of genetic pollution, i.e. uncontrolled hybridization, introgression and genetic swamping. Genetic pollution leads to homogenization or replacement of local genomes as a result of either a numerical and/or fitness advantage of an introduced species. Hybridization and introgression are side-effects of introduction and invasion. These phenomena can be especially detrimental to rare species that come into contact with more abundant ones. The abundant species can interbreed with the rare species, swamping its gene pool. This problem is not always apparent from morphological (outward appearance) observations alone. Some degree of gene flow is normal adaptation, and not all gene and genotype constellations can be preserved. However, hybridization with or without introgression may, nevertheless, threaten a rare species' existence.
What behavior causes swamping of a gene pool?
The answer is the following:
The abundant species can interbreed with the rare species
