At the start of a classic valley glacier is a bowl-shaped cirque, which has escarped walls on three sides but is open on the side that descends into the valley. Cirques are where ice begins to accumulate in a glacier. Two glacial cirques may form back to back and erode their backwalls until only a narrow ridge, called an arete is left. This structure may result in a mountain pass. If multiple cirques encircle a single mountain, they create pointed pyramidal peaks; particularly steep examples are called horns.
What are shallow cirques called?
A: unanswerable

Due to insistence by the International Federation of Association Football (FIFA), the international governing body of football, that domestic leagues reduce the number of games clubs played, the number of clubs was reduced to 20 in 1995 when four teams were relegated from the league and only two teams promoted. On 8 June 2006, FIFA requested that all major European leagues, including Italy's Serie A and Spain's La Liga be reduced to 18 teams by the start of the 200708 season. The Premier League responded by announcing their intention to resist such a reduction. Ultimately, the 200708 season kicked off again with 20 teams.
What was the number of clubs reduced to in 1995.
A: the number of clubs was reduced to 20 in 1995

Some commentators have defined reverse discrimination as a policy or practice in which members of a majority are discriminated against in favor of a historically disadvantaged group or minority.[non-primary source needed] Many argue that reverse discrimination results from affirmative action policies and that these policies are just another form of discrimination no different from examples in the past. People like Ward Connerly assert that affirmative action requires the very discrimination it is seeking to eliminate. According to these opponents, this contradiction might make affirmative action counter-productive. One argument for reverse discrimination is the idea that affirmative action encourages mediocrity and incompetence. Job positions would not be offered to the applicants who are the most qualified, but to applicants with a special trait such as a certain race, ethnicity, or gender. For example, opponents say affirmative action causes unprepared applicants to be accepted in highly demanding educational institutions or jobs which result in eventual failure (see, for example, Richard Sander's study of affirmative action in Law School, bar exam and eventual performance at law firms). Other opponents say that affirmative action lowers the bar and so denies those who strive for excellence on their own merit and the sense of real achievement. Opponents of affirmative action suggest that merit should be the primary factor considered in applying for job positions, college, graduate school, etc.
An argument against affirmative action is that it discourages what?
A: unanswerable

Replacing the classical physics in use since the end of the scientific revolution, modern physics arose in the early 20th century with the advent of quantum physics, substituting mathematical studies for experimental studies and examining equations to build a theoretical structure.[citation needed] The old quantum theory was a collection of results which predate modern quantum mechanics, but were never complete or self-consistent. The collection of heuristic prescriptions for quantum mechanics were the first corrections to classical mechanics. Outside the realm of quantum physics, the various aether theories in classical physics, which supposed a "fifth element" such as the Luminiferous aether, were nullified by the Michelson-Morley experimentan attempt to detect the motion of earth through the aether. In biology, Darwinism gained acceptance, promoting the concept of adaptation in the theory of natural selection. The fields of geology, astronomy and psychology also made strides and gained new insights. In medicine, there were advances in medical theory and treatments.
What is the Michelson-Morley experiment?
A:
an attempt to detect the motion of earth through the aether
