Input: Read this: The Aksumites erected a number of large stelae, which served a religious purpose in pre-Christian times. One of these granite columns, the obelisk of Aksum, is the largest such structure in the world, standing at 90 feet. Under Ezana (fl. 320360), Aksum later adopted Christianity. In the 7th century, early Muslims from Mecca also sought refuge from Quraysh persecution by travelling to the kingdom, a journey known in Islamic history as the First Hijra. It is also the alleged resting place of the Ark of the Covenant and the purported home of the Queen of Sheba.
Question: In what year was the obelisk of Aksum carved?

QUES: Marshall's words and future court decisions gave Congress much latitude in delegating powers. It was not until the 1930s that the Supreme Court held a delegation of authority unconstitutional. In a case involving the creation of the National Recovery Administration called A.L.A. Schechter Poultry Corp. v. United States, 295 U.S. 495 (1935), Congress could not authorize the president to formulate codes of "fair competition." It was held that Congress must set some standards governing the actions of executive officers. The Court, however, has deemed that phrases such as "just and reasonable," "public interest" and "public convenience" suffice.

In which case was Congress able to authorize the president to formulate codes?

QUES: Other major bluegrass mandolinists who emerged in the early 1950s and are still active include Jesse McReynolds (of Jim and Jesse) who invented a syncopated banjo-roll-like style called crosspickingand Bobby Osborne of the Osborne Brothers, who is a master of clarity and sparkling single-note runs. Highly respected and influential modern bluegrass players include Herschel Sizemore, Doyle Lawson, and the multi-genre Sam Bush, who is equally at home with old-time fiddle tunes, rock, reggae, and jazz. Ronnie McCoury of the Del McCoury Band has won numerous awards for his Monroe-influenced playing. The late John Duffey of the original Country Gentlemen and later the Seldom Scene did much to popularize the bluegrass mandolin among folk and urban audiences, especially on the east coast and in the Washington, D.C. area.
Who won no awards for his Monroe influenced music?

Special procedures apply to legislation passed by Tynwald, the legislature of the Isle of Man. Before the lordship of the Island was purchased by the British Crown in 1765 (the Revestment), the assent of the Lord of Mann to a bill was signified by letter to the governor. After 1765, royal assent was at first signified by letter from the Secretary of State to the governor; but, during the British Regency, the practice began of granting royal assent by Order in Council, which continues to this day, though limited to exceptional cases since 1981.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who signified the letter of royal assent in America after 1765?
Ah, so.. unanswerable

Question: Task Manager has been redesigned, including a new processes tab with the option to display fewer or more details of running applications and background processes, a heat map using different colors indicating the level of resource usage, network and disk counters, grouping by process type (e.g. applications, background processes and Windows processes), friendly names for processes and a new option which allows users to search the web to find information about obscure processes. Additionally, the Blue Screen of Death has been updated with a simpler and modern design with less technical information displayed.
Try to answer this question if possible: How can users find out more about obscure Windows 8 processes?

Input: Read this: On tracks that London Underground share with National Rail third-rail stock (the Bakerloo and District lines both have such sections), the centre rail is connected to the running rails, allowing both types of train to operate, at a compromise voltage of 660 V. Underground trains pass from one section to the other at speed; lineside electrical connections and resistances separate the two types of supply. These routes were originally solely electrified on the four-rail system by the LNWR before National Rail trains were rewired to their standard three-rail system to simplify rolling stock use.
Question: What is the maximum voltage of the two UK rail systems?
