Problem: Nigeria:

Nigeria is home to a substantial network of organised crime, active especially in drug trafficking. Nigerian criminal groups are heavily involved in drug trafficking, shipping heroin from Asian countries to Europe and America; and cocaine from South America to Europe and South Africa. . The various Nigerian Confraternities or "campus cults" are active in both organised crime and in political violence as well as providing a network of corruption within Nigeria. As confraternities have extensive connections with political and military figures, they offer excellent alumni networking opportunities. The Supreme Vikings Confraternity, for example, boasts that twelve members of the Rivers State House of Assembly are cult members. On lower levels of society, there are the "area boys", organised gangs mostly active in Lagos who specialise in mugging and small-scale drug dealing. According to official statistics, gang violence in Lagos resulted in 273 civilians and 84 policemen killed in the period of August 2000 to May 2001.

Context and question: The racial preferences debate related to admission to US colleges and universities reflects competing notions of the mission of colleges: "To what extent should they pursue scholarly excellence, to what extent civic goods, and how should these purposes be balanced?". Scholars such as Ronald Dworkin have asserted that no college applicant has a right to expect that a university will design its admissions policies in a way that prizes any particular set of qualities. In this view, admission is not an honor bestowed to reward superior merit but rather a way to advance the mission as each university defines it. If diversity is a goal of the university and their racial preferences do not discriminate against applicants based on hatred or contempt, then affirmative action can be judged acceptable based on the criteria related to the mission the university sets for itself.
What does the racial preferences debate not indicate about universities and colleges?
Answer: unanswerable

In the Roman era, copper was principally mined on Cyprus, the origin of the name of the metal from aes сyprium (metal of Cyprus), later corrupted to сuprum, from which the words copper (English), cuivre (French), Koper (Dutch) and Kupfer (German) are all derived. Its compounds are commonly encountered as copper(II) salts, which often impart blue or green colors to minerals such as azurite, malachite and turquoise and have been widely used historically as pigments. Architectural structures built with copper corrode to give green verdigris (or patina). Decorative art prominently features copper, both by itself and in the form of pigments.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What componds are common in copper?
Ah, so..
copper(II) salts
