Problem: Presbyterianism:

Presbyterianism first officially arrived in Colonial America in 1703 with the establishment of the first Presbytery in Philadelphia. In time, the presbytery would be joined by two more to form a synod (1717) and would eventually evolve into the Presbyterian Church in the United States of America in 1789. The nation's largest Presbyterian denomination, the Presbyterian Church (U.S.A.) PC (USA) can trace their heritage back to the original PCUSA, as can the Presbyterian Church in America (PCA), the Orthodox Presbyterian Church (OPC), the Bible Presbyterian Church (BPC), the Cumberland Presbyterian Church (CPC), the Cumberland Presbyterian Church in America the Evangelical Presbyterian Church (EPC) and the Evangelical Covenant Order of Presbyterians (ECO).

In what year would the original churches evolve into the Presbyterian Church in the United States of America?

Problem: In the early 1990s, Dell sold its products through Best Buy, Costco and Sam's Club stores in the United States. Dell stopped this practice in 1994, citing low profit-margins on the business, exclusively distributing through a direct-sales model for the next decade. In 2003, Dell briefly sold products in Sears stores in the U.S. In 2007, Dell started shipping its products to major retailers in the U.S. once again, starting with Sam's Club and Wal-Mart. Staples, the largest office-supply retailer in the U.S., and Best Buy, the largest electronics retailer in the U.S., became Dell retail partners later that same year.

Context and question: In the 1950s and the 1960s, Paris became one front of the Algerian War for independence; in August 1961, the pro-independence FLN targeted and killed 11 Paris policemen, leading to the imposition of a curfew on Muslims of Algeria (who, at that time, were French citizens). On 17 October 1961, an unauthorised but peaceful protest demonstration of Algerians against the curfew led to violent confrontations between the police and demonstrators, in which at least 40 people were killed, including some thrown into the Seine. The anti-independence Organisation de l'armee secrete (OAS), for their part, carried out a series of bombings in Paris throughout 1961 and 1962.
What was the result of the police officer killing?
Answer: curfew on Muslims of Algeria

QUES: German beacons operated on the medium-frequency band and the signals involved a two-letter Morse identifier followed by a lengthy time-lapse which enabled the Luftwaffe crews to determine the signal's bearing. The Meacon system involved separate locations for a receiver with a directional aerial and a transmitter. The receipt of the German signal by the receiver was duly passed to the transmitter, the signal to be repeated. The action did not guarantee automatic success. If the German bomber flew closer to its own beam than the Meacon then the former signal would come through the stronger on the direction finder. The reverse would apply only if the meacon were closer.

The German beacons used what frequency band?
What is the answer?
