Problem: Affirmative action is a subject of controversy. Some policies adopted as affirmative action, such as racial quotas or gender quotas for collegiate admission, have been criticized as a form of reverse discrimination, and such implementation of affirmative action has been ruled unconstitutional by the majority opinion of Gratz v. Bollinger. Affirmative action as a practice was upheld by the Supreme Court's decision in Grutter v. Bollinger in 2003. Affirmative action policies were developed in order to correct decades of discrimination stemming from the Reconstruction Era by granting disadvantaged minorities opportunities. Many believe that the diversity of current American society suggests that affirmative action policies succeeded and are no longer required. Opponents of affirmative action argue that these policies are outdated and lead to reverse discrimination which entails favoring one group over another based upon racial preference rather than achievement.
Not having quotas regarding admissions or employment has been criticized and said to be what kind of discrimination?

Starting in 1984, some of these DJs, inspired by Jesse Saunders' success with "On and On", tried their hand at producing and releasing original compositions. These compositions used newly affordable electronic instruments to emulate not just Saunders' song, but the edited, enhanced styles of disco and other dance music they already favored. These homegrown productions were played on Chicago-area radio and in local discothèques catering mainly to African-American and gay audiences. By 1985, although the exact origins of the term are debated, "house music" encompassed these locally produced recordings. Subgenres of house, including deep house and acid house, quickly emerged and gained traction.
what area radio was house music generally played on?
A: Chicago-area radio


Context and question: The end of a treaty, the eschatocol (or closing protocol), is often signaled by a clause like "in witness whereof" or "in faith whereof," the parties have affixed their signatures, followed by the words "DONE at," then the site(s) of the treaty's execution and the date(s) of its execution. The date is typically written in its most formal, longest possible form. For example, the Charter of the United Nations was "DONE at the city of San Francisco the twenty-sixth day of June, one thousand nine hundred and forty-five." If the treaty is executed in multiple copies in different languages, that fact is always noted, and is followed by a stipulation that the versions in different languages are equally authentic.
How is the date typically written in a treaty?
Answer: its most formal, longest possible form


Question: Mobbing can be an interspecies activity: it is common for birds to respond to mobbing calls of a different species. Many birds will show up at the sight of mobbing and watch and call, but not participate. It should also be noted that some species can be on both ends of a mobbing attack. Crows are frequently mobbed by smaller songbirds as they prey on eggs and young from these birds' nests, but these same crows will cooperate with smaller birds to drive away hawks or larger mammalian predators. On occasion, birds will mob animals that pose no threat.
Is there an answer to this question: Which bird is an example of being both a predator and defender in mobbing attacks?

Answer: Crows

Many adaptations of the instrument have been done to cater to the special needs of Indian Carnatic music. In Indian classical music and Indian light music, the mandolin, which bears little resemblance to the European mandolin, is usually tuned E-B-E-B. As there is no concept of absolute pitch in Indian classical music, any convenient tuning maintaining these relative pitch intervals between the strings can be used. Another prevalent tuning with these intervals is C-G-C-G, which corresponds to Sa-Pa-Sa-Pa in the Indian carnatic classical music style. This tuning corresponds to the way violins are tuned for carnatic classical music. This type of mandolin is also used in Bhangra, dance music popular in Punjabi culture.
These mandolin are used in a popular dance music called? 
A:
Bhangra
