In 1681, in partial repayment of a debt, Charles II of England granted William Penn a charter for what would become the Pennsylvania colony. Despite the royal charter, Penn bought the land from the local Lenape to be on good terms with the Native Americans and ensure peace for his colony. Penn made a treaty of friendship with Lenape chief Tammany under an elm tree at Shackamaxon, in what is now the city's Fishtown section. Penn named the city Philadelphia, which is Greek for brotherly love (from philos, "love" or "friendship", and adelphos, "brother"). As a Quaker, Penn had experienced religious persecution and wanted his colony to be a place where anyone could worship freely. This tolerance, far more than afforded by most other colonies, led to better relations with the local Native tribes and fostered Philadelphia's rapid growth into America's most important city. Penn planned a city on the Delaware River to serve as a port and place for government. Hoping that Philadelphia would become more like an English rural town instead of a city, Penn laid out roads on a grid plan to keep houses and businesses spread far apart, with areas for gardens and orchards. The city's inhabitants did not follow Penn's plans, as they crowded by the Delaware River, the port, and subdivided and resold their lots. Before Penn left Philadelphia for the last time, he issued the Charter of 1701 establishing it as a city. It became an important trading center, poor at first, but with tolerable living conditions by the 1750s. Benjamin Franklin, a leading citizen, helped improve city services and founded new ones, such as fire protection, a library, and one of the American colonies' first hospitals.
When was Philadelphia established as a city?
A: 1701

Upon its founding in 1949, West Germany had eleven states. These were reduced to nine in 1952 when three south-western states (South Baden, Württemberg-Hohenzollern, and Württemberg-Baden) merged to form Baden-Württemberg. From 1957, when the French-occupied Saar Protectorate was returned and formed into the Saarland, the Federal Republic consisted of ten states, which are referred to as the "Old States" today. West Berlin was under the sovereignty of the Western Allies and neither a Western German state nor part of one. However, it was in many ways de facto integrated with West Germany under a special status.
What are referred to as the 'new states'?
A: unanswerable

Friedrich August von Hayek was born in Vienna to August von Hayek and Felicitas Hayek (née von Juraschek). Friedrich's father, from whom he received his middle name, was also born in Vienna in 1871. He was a medical doctor employed by the municipal ministry of health, with passion in botany, in which he wrote a number of monographs. August von Hayek was also a part-time botany lecturer at the University of Vienna. Friedrich's mother was born in 1875 to a wealthy, conservative, land-owning family. As her mother died several years prior to Friedrich's birth, Felicitas gained a significant inheritance which provided as much as half of her and August's income during the early years of their marriage. Hayek was the oldest of three brothers, Heinrich (1900–69) and Erich (1904–86), who were one-and-a-half and five years younger than him.
From whom did Felicitas inherit her wealth?
A:
her mother
