Problem: Raleigh is located in the northeast central region of North Carolina, where the Piedmont and Atlantic Coastal Plain regions meet. This area is known as the "fall line" because it marks the elevation inland at which waterfalls begin to appear in creeks and rivers. As a result, most of Raleigh features gently rolling hills that slope eastward toward the state's flat coastal plain. Its central Piedmont location situates Raleigh about two hours west of Atlantic Beach, North Carolina, by car and four hours east of the Great Smoky Mountains. The city is 155 miles (249 km) south of Richmond, Virginia, 263 miles (423 km) south of Washington, D.C., and 150 miles (240 km) northeast of Charlotte, North Carolina.
How far is Raleigh from Richmond?
The answer is the following: 155

Problem: In 885 AD the Armenians reestablished themselves as a sovereign kingdom under the leadership of Ashot I of the Bagratid Dynasty. A considerable portion of the Armenian nobility and peasantry fled the Byzantine occupation of Bagratid Armenia in 1045, and the subsequent invasion of the region by Seljuk Turks in 1064. They settled in large numbers in Cilicia, an Anatolian region where Armenians were already established as a minority since Roman times. In 1080, they founded an independent Armenian Principality then Kingdom of Cilicia, which became the focus of Armenian nationalism. The Armenians developed close social, cultural, military, and religious ties with nearby Crusader States, but eventually succumbed to Mamluk invasions. In the next few centuries, Djenghis Khan, Timurids, and the tribal Turkic federations of the Ak Koyunlu and the Kara Koyunlu ruled over the Armenians.
What dynasty was Ashot I part of?
The answer is the following: the Bagratid Dynasty

Problem: The framers of the US Constitution were influenced by the Constitution of the Republic of the United Provinces, as Federalist No. 20, by James Madison, shows. Such influence appears, however, to have been of a negative nature, as Madison describes the Dutch confederacy as exhibiting "Imbecility in the government; discord among the provinces; foreign influence and indignities; a precarious existence in peace, and peculiar calamities from war." Apart from this, the American Declaration of Independence is similar to the Act of Abjuration, essentially the declaration of independence of the United Provinces, but concrete evidence that the former directly influenced the latter is absent.
The American Declaration of Independence is similar to what?
The answer is the following: the Act of Abjuration, essentially the declaration of independence of the United Provinces

Problem: The formation of the ice giants, Neptune and Uranus, has proven difficult to model precisely. Current models suggest that the matter density in the outer regions of the Solar System was too low to account for the formation of such large bodies from the traditionally accepted method of core accretion, and various hypotheses have been advanced to explain their formation. One is that the ice giants were not formed by core accretion but from instabilities within the original protoplanetary disc and later had their atmospheres blasted away by radiation from a nearby massive OB star.
What is too low to account for the formation of Neptune?
The answer is the following:
matter density
