Problem: 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 a subgroup of a symmetric group SN can be expressed as?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Most food in Alaska is transported into the state from "Outside", and shipping costs make food in the cities relatively expensive. In rural areas, subsistence hunting and gathering is an essential activity because imported food is prohibitively expensive. Though most small towns and villages in Alaska lie along the coastline, the cost of importing food to remote villages can be high, because of the terrain and difficult road conditions, which change dramatically, due to varying climate and precipitation changes. The cost of transport can reach as high as 50 per pound ($1.10/kg) or more in some remote areas, during the most difficult times, if these locations can be reached at all during such inclement weather and terrain conditions. The cost of delivering a 1 US gallon (3.8 L) of milk is about $3.50 in many villages where per capita income can be $20,000 or less. Fuel cost per gallon is routinely 2030 higher than the continental United States average, with only Hawaii having higher prices.
How much does it cost to transport a gallon of milk in some urban areas of Alaska?
A: unanswerable

Context and question: Nontrinitarians, such as Unitarians, Christadelphians and Jehovah's Witnesses also acknowledge Mary as the biological mother of Jesus Christ, but do not recognise Marian titles such as "Mother of God" as these groups generally reject Christ's divinity. Since Nontrinitarian churches are typically also mortalist, the issue of praying to Mary, whom they would consider "asleep", awaiting resurrection, does not arise. Emanuel Swedenborg says God as he is in himself could not directly approach evil spirits to redeem those spirits without destroying them (Exodus 33:20, John 1:18), so God impregnated Mary, who gave Jesus Christ access to the evil heredity of the human race, which he could approach, redeem and save.
Unittarians, Christadelphians and Jehovah's Witnesses are examples of what kind of church?
Answer: Nontrinitarians

Question: In the United Kingdom, it has been alleged that peerages have been awarded to contributors to party funds, the benefactors becoming members of the House of Lords and thus being in a position to participate in legislating. Famously, Lloyd George was found to have been selling peerages. To prevent such corruption in the future, Parliament passed the Honours (Prevention of Abuses) Act 1925 into law. Thus the outright sale of peerages and similar honours became a criminal act. However, some benefactors are alleged to have attempted to circumvent this by cloaking their contributions as loans, giving rise to the 'Cash for Peerages' scandal.
Is there an answer to this question: What can people who approve loans for a living take part in in government?

Answer: unanswerable

Question: On Saturday, 24 June 1950, U.S. Secretary of State Dean Acheson informed President Truman that the North Koreans had invaded South Korea. Truman and Acheson discussed a U.S. invasion response and agreed that the United States was obligated to act, paralleling the North Korean invasion with Adolf Hitler's aggressions in the 1930s, with the conclusion being that the mistake of appeasement must not be repeated. Several U.S. industries were mobilized to supply materials, labor, capital, production facilities, and other services necessary to support the military objectives of the Korean War. However, President Truman later acknowledged that he believed fighting the invasion was essential to the American goal of the global containment of communism as outlined in the National Security Council Report 68 (NSC-68) (declassified in 1975):
Is there an answer to this question: What did the US not want to see repeated?

Answer:
the mistake of appeasement
