QUES: A group is called finite if it has a finite number of elements. The number of elements is called the order of the group. An important class is the symmetric groups SN, the groups of permutations of N letters. For example, the symmetric group on 3 letters S3 is the group consisting of all possible orderings of the three letters ABC, i.e. contains the elements ABC, ACB, ..., up to CBA, in total 6 (or 3 factorial) elements. This class is fundamental insofar as any finite group can be expressed as a subgroup of a symmetric group SN for a suitable integer N (Cayley's theorem). Parallel to the group of symmetries of the square above, S3 can also be interpreted as the group of symmetries of an equilateral triangle.

What can be described as the group of symmetries of an equilateral triangle?
What is the answer?
ANS: S3
QUES: Higher education, also called tertiary, third stage, or postsecondary education, is the non-compulsory educational level that follows the completion of a school such as a high school or secondary school. Tertiary education is normally taken to include undergraduate and postgraduate education, as well as vocational education and training. Colleges and universities mainly provide tertiary education. Collectively, these are sometimes known as tertiary institutions. Individuals who complete tertiary education generally receive certificates, diplomas, or academic degrees.

People do not receive certificates from what level of education?
What is the answer?
ANS: unanswerable
QUES: Genocide has become an official term used in international relations. The word genocide was not in use before 1944. Before this, in 1941, Winston Churchill described the mass killing of Russian prisoners of war and civilians as "a crime without a name". In that year, a Polish-Jewish lawyer named Raphael Lemkin, described the policies of systematic murder founded by the Nazis as genocide. The word genocide is the combination of the Greek prefix geno- (meaning tribe or race) and caedere (the Latin word for to kill). The word is defined as a specific set of violent crimes that are committed against a certain group with the attempt to remove the entire group from existence or to destroy them.

When was the word "genocide" last used?
What is the answer?

unanswerable
