Problem: England national football team:

England qualified for the 1970 FIFA World Cup in Mexico as reigning champions, and reached the quarter-finals, where they were knocked out by West Germany. England had been 20 up, but were eventually beaten 32 after extra time. They failed in qualification for the 1974, leading to Ramsey's dismissal, and 1978 FIFA World Cups. Under Ron Greenwood, they managed to qualify for the 1982 FIFA World Cup in Spain (the first time competitively since 1962); despite not losing a game, they were eliminated in the second group stage.

In what year did Ron Greenwood take over leadership of England's football team?

Problem: Tort law covers the entire imaginable spectrum of wrongs which humans can inflict upon each other, and of course, partially overlaps with wrongs also punishable by criminal law. Although the American Law Institute has attempted to standardize tort law through the development of several versions of the Restatement of Torts, many states have chosen to adopt only certain sections of the Restatements and to reject others. Thus, because of its immense size and diversity, American tort law cannot be easily summarized.
Why can American tort law not be easily summarized?

Answer: because of its immense size and diversity

In Eastern Christianity heresy most commonly refers to those beliefs declared heretical by the first seven Ecumenical Councils.[citation needed] Since the Great Schism and the Protestant Reformation, various Christian churches have also used the concept in proceedings against individuals and groups those churches deemed heretical.

Context and question: Arsenal began winning silverware again with the surprise appointment of club physiotherapist Bertie Mee as manager in 1966. After losing two League Cup finals, they won their first European trophy, the 196970 Inter-Cities Fairs Cup. This was followed by an even greater triumph: their first League and FA Cup double in 197071. This marked a premature high point of the decade; the Double-winning side was soon broken up and the following decade was characterised by a series of near misses, starting with Arsenal finishing as FA Cup runners up in 1972, and First Division runners-up in 197273.
Who was Arsenal's manager in 1965?
Answer: unanswerable

Question: On 11 October 1951, the Wafd government abrogated the 1936 Anglo-Egyptian Treaty, which had given the British control over the Suez Canal until 1956. The popularity of this move, as well as that of government-sponsored guerrilla attacks against the British, put pressure on Nasser to act. According to Sadat, Nasser decided to wage "a large scale assassination campaign". In January 1952, he and Hassan Ibrahim attempted to kill the royalist general Hussein Sirri Amer by firing their submachine guns at his car as he drove through the streets of Cairo. Instead of killing the general, the attackers wounded an innocent female passerby. Nasser recalled that her wails "haunted" him and firmly dissuaded him from undertaking similar actions in the future.
Is there an answer to this question: Who did Nasser's group try to assassinate?

Answer: Hussein Sirri Amer

Unicode defines two mapping methods: the Unicode Transformation Format (UTF) encodings, and the Universal Coded Character Set (UCS) encodings. An encoding maps (possibly a subset of) the range of Unicode code points to sequences of values in some fixed-size range, termed code values. The numbers in the names of the encodings indicate the number of bits per code value (for UTF encodings) or the number of bytes per code value (for UCS encodings). UTF-8 and UTF-16 are probably the most commonly used encodings. UCS-2 is an obsolete subset of UTF-16; UCS-4 and UTF-32 are functionally equivalent.
What are the most commonly used encodings?
A:
UTF-8 and UTF-16
