The new head of state, Ibrahim Babangida, declared himself president and commander in chief of the armed forces and the ruling Supreme Military Council. He set 1990 as the official deadline for a return to democratic governance. Babangida's tenure was marked by a flurry of political activity: he instituted the International Monetary Fund's Structural Adjustment Program (SAP) to aid in the repayment of the country's crushing international debt, which most federal revenue was dedicated to servicing. He enrolled Nigeria in the Organisation of the Islamic Conference, which aggravated religious tensions in the country.
What controversial religious group did Nigeria join?

Adolescence is also a time for rapid cognitive development. Piaget describes adolescence as the stage of life in which the individual's thoughts start taking more of an abstract form and the egocentric thoughts decrease. This allows the individual to think and reason in a wider perspective. A combination of behavioural and fMRI studies have demonstrated development of executive functions, that is, cognitive skills that enable the control and coordination of thoughts and behaviour, which are generally associated with the prefrontal cortex. The thoughts, ideas and concepts developed at this period of life greatly influence one's future life, playing a major role in character and personality formation.

In the year 1563 the influential Ecumenical Council of Trent, headed by Pope Pius IV, wrote about the importance of selecting good Cardinals. According to this historic council "nothing is more necessary to the Church of God than that the holy Roman pontiff apply that solicitude which by the duty of his office he owes the universal Church in a very special way by associating with himself as cardinals the most select persons only, and appoint to each church most eminently upright and competent shepherds; and this the more so, because our Lord Jesus Christ will require at his hands the blood of the sheep of Christ that perish through the evil government of shepherds who are negligent and forgetful of their office."
Who was the pope who headed the Ecumencial Council of Trent in that year?
