Problem: Ethnocentrism, tribalism, religious persecution, and prebendalism have affected Nigerian politics both prior and subsequent to independence in 1960. Kin-selective altruism has made its way into Nigerian politics, resulting in tribalist efforts to concentrate Federal power to a particular region of their interests. Nationalism has also led to active secessionist movements such as MASSOB, Nationalist movements such as Oodua Peoples Congress, Movement for the Emancipation of the Niger Delta and a civil war. Nigeria's three largest ethnic groups (Hausa, Igbo and Yoruba) have maintained historical preeminence in Nigerian politics; competition amongst these three groups has fuelled corruption and graft.
When did Nigeria get independence?

Problem: For its 2015 season, the league consisted of 12 teams, all from the United States; however, upon the completion of the regular season, the league announced that the two teams it had assumed operation of during the season would cease all operations effective immediately; a regular season game slated between the two had previously been canceled and declared a tie. Subsequently, one of the remaining teams, the Spokane Shock, severed its ties with the league to join the competing IFL. The AFL is divided into two conferences  –  the American Conference and National Conference. Starting 2016, each conference will have only four teams as the champion San Jose SaberCats announced in November 2015 that they were ceasing activity for "reasons not associated with League operations."
How many conferences does the AFL have?
The answer is the following: 2

Problem: Ter-Petrosyan led Armenia alongside Defense Minister Vazgen Sargsyan through the Nagorno-Karabakh War with neighboring Azerbaijan. The initial post-Soviet years were marred by economic difficulties, which had their roots early in the Karabakh conflict when the Azerbaijani Popular Front managed to pressure the Azerbaijan SSR to instigate a railway and air blockade against Armenia. This move effectively crippled Armenia's economy as 85% of its cargo and goods arrived through rail traffic. In 1993, Turkey joined the blockade against Armenia in support of Azerbaijan.
When did Turkey decide to become part of the blockade against Armenia?
The answer is the following: 1993

Problem: In the Regal era, a rex sacrorum (king of the sacred rites) supervised regal and state rites in conjunction with the king (rex) or in his absence, and announced the public festivals. He had little or no civil authority. With the abolition of monarchy, the collegial power and influence of the Republican pontifices increased. By the late Republican era, the flamines were supervised by the pontifical collegia. The rex sacrorum had become a relatively obscure priesthood with an entirely symbolic title: his religious duties still included the daily, ritual announcement of festivals and priestly duties within two or three of the latter but his most important priestly role – the supervision of the Vestals and their rites – fell to the more politically powerful and influential pontifex maximus.
What individual became more powerful during the late Republic?
The answer is the following:
pontifex maximus
