This set inherits a group operation (sometimes called coset multiplication, or coset addition) from the original group G: (gN) (hN) = (gh)N for all g and h in G. This definition is motivated by the idea (itself an instance of general structural considerations outlined above) that the map G G / N that associates to any element g its coset gN be a group homomorphism, or by general abstract considerations called universal properties. The coset eN = N serves as the identity in this group, and the inverse of gN in the quotient group is (gN)1 = (g1)N.e["]
What are group homomorphisms called?
A: unanswerable

Terry Neill was recruited by the Arsenal board to replace Bertie Mee on 9 July 1976 and at the age of 34 he became the youngest Arsenal manager to date. With new signings like Malcolm Macdonald and Pat Jennings, and a crop of talent in the side such as Liam Brady and Frank Stapleton, the club enjoyed their best form since the 1971 double, reaching a trio of FA Cup finals (1978, 1979 and 1980), and losing the 1980 European Cup Winners' Cup Final on penalties. The club's only success during this time was a last-minute 32 victory over Manchester United in the 1979 FA Cup Final, widely regarded as a classic.
In what years did Arsenal get into the FA Cup finals?
A: 1978, 1979 and 1980

Royal assent is the method by which a country's constitutional monarch (possibly through a delegated official) formally approves an act of that nation's parliament, thus making it a law or letting it be promulgated as law. In the vast majority of contemporary monarchies, this act is considered to be little more than a formality; even in those nations which still permit their ruler to withhold the royal assent (such as the United Kingdom, Norway, and Liechtenstein), the monarch almost never does so, save in a dire political emergency or upon the advice of their government. While the power to withhold royal assent was once exercised often in European monarchies, it is exceedingly rare in the modern, democratic political atmosphere that has developed there since the 18th century.
Which power is extremely common in modern democratic atmosphere?
A: unanswerable
