Article: 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.

Question: What can be described as the group of symmetries of an equilateral triangle?
Ans: S3

Here is a question about this article: On leaving the University of Oxford, in 1676, Edmond Halley visited Saint Helena and set up an astronomical observatory with a 7.3-metre-long (24 ft) aerial telescope with the intention of studying stars from the Southern Hemisphere. The site of this telescope is near Saint Mathew's Church in Hutt's Gate, in the Longwood district. The 680-metre (2,230 ft) high hill there is named for him and is called Halley's Mount.
What is the answer to this question: What hemisphere of stars did Edmond Halley want to study with the telescope?
****
So... Southern

The answer: St. Nicholas Park

Problem: Please answer a question about the following article about Cotton:
The era of manufactured fibers began with the development of rayon in France in the 1890s. Rayon is derived from a natural cellulose and cannot be considered synthetic, but requires extensive processing in a manufacturing process, and led the less expensive replacement of more naturally derived materials. A succession of new synthetic fibers were introduced by the chemicals industry in the following decades. Acetate in fiber form was developed in 1924. Nylon, the first fiber synthesized entirely from petrochemicals, was introduced as a sewing thread by DuPont in 1936, followed by DuPont's acrylic in 1944. Some garments were created from fabrics based on these fibers, such as women's hosiery from nylon, but it was not until the introduction of polyester into the fiber marketplace in the early 1950s that the market for cotton came under threat. The rapid uptake of polyester garments in the 1960s caused economic hardship in cotton-exporting economies, especially in Central American countries, such as Nicaragua, where cotton production had boomed tenfold between 1950 and 1965 with the advent of cheap chemical pesticides. Cotton production recovered in the 1970s, but crashed to pre-1960 levels in the early 1990s.
What company produced nylon and acrylic in the 1930s and 1940s?
A: DuPont

Executive power is vested, with exceptions and qualifications, in the President. By law (Section 2.) the president becomes the Commander in Chief of the Army and Navy, Militia of several states when called into service, has power to make treaties and appointments to office "with the Advice and Consent of the Senate," receive Ambassadors and Public Ministers, and "take care that the laws be faithfully executed" (Section 3.) By using these words, the Constitution does not require the president to personally enforce the law; rather, officers subordinate to the president may perform such duties. The Constitution empowers the president to ensure the faithful execution of the laws made by Congress and approved by the President. Congress may itself terminate such appointments, by impeachment, and restrict the president. Bodies such as the War Claims Commission, the Interstate Commerce Commission and the Federal Trade Commissionall quasi-judicialoften have direct Congressional oversight.

Which branches of the national military does the U.S. president command?
Answer: Army and Navy

According to Capitol Record's A&R, Joe Weinberger, he was approached by West and almost signed a deal with him, but another person in the company convinced Capitol's president not to. Desperate to keep West from defecting to another label, then-label head Damon Dash reluctantly signed West to Roc-A-Fella Records. Jay-Z later admitted that Roc-A-Fella was initially reluctant to support West as a rapper, claiming that many saw him as a producer first and foremost, and that his background contrasted with that of his labelmates.
What record company eventually signed Kanye West?
Roc-A-Fella
