Context and question: By 1790, the Jewish population of Alsace was approximately 22,500, about 3% of the provincial population. They were highly segregated and subject to long-standing anti-Jewish regulations. They maintained their own customs, Yiddish language, and historic traditions within the tightly-knit ghettos; they adhered to Talmudic law enforced by their rabbis. Jews were barred from most cities and instead lived in villages. They concentrated in trade, services, and especially in money lending. They financed about a third of the mortgages in Alsace. Official tolerance grew during the French Revolution, with full emancipation in 1791. However, local antisemitism also increased and Napoleon turned hostile in 1806, imposing a one-year moratorium on all debts owed to Jews.[citation needed] In the 1830-1870 era most Jews moved to the cities, where they integrated and acculturated, as antisemitism sharply declined. By 1831, the state began paying salaries to official rabbis, and in 1846 a special legal oath for Jews was discontinued. Antisemitic local riots occasionally occurred, especially during the Revolution of 1848. Merger of Alsace into Germany in 1871-1918 lessened antisemitic violence.

Context and question: In December 2011, the system went into operation on a trial basis. It has started providing navigation, positioning and timing data to China and the neighbouring area for free from 27 December. During this trial run, Compass will offer positioning accuracy to within 25 meters, but the precision will improve as more satellites are launched. Upon the system's official launch, it pledged to offer general users positioning information accurate to the nearest 10 m, measure speeds within 0.2 m per second, and provide signals for clock synchronisation accurate to 0.02 microseconds.
During the trial period, within how many meters was the NSEW system's positioning accuracy?
Answer: unanswerable
Context and question: New Haven has a long tradition of urban planning and a purposeful design for the city's layout. The city could be argued to have some of the first preconceived layouts in the country. Upon founding, New Haven was laid out in a grid plan of nine square blocks; the central square was left open, in the tradition of many New England towns, as the city green (a commons area). The city also instituted the first public tree planting program in America. As in other cities, many of the elms that gave New Haven the nickname "Elm City" perished in the mid-20th century due to Dutch Elm disease, although many have since been replanted. The New Haven Green is currently home to three separate historic churches which speak to the original theocratic nature of the city. The Green remains the social center of the city today. It was named a National Historic Landmark in 1970.
For what environmental initiative is the city of New Haven known, primarily for instituting the first of its kind in America?
Answer:
public tree planting program
