Problem: The death penalty is sought and applied more often in some jurisdictions, not only between states but within states. A 2004 Cornell University study showed that while 2.5 percent of murderers convicted nationwide were sentenced to the death penalty, in Nevada 6 percent were given the death penalty. Texas gave 2 percent of murderers a death sentence, less than the national average. Texas, however, executed 40 percent of those sentenced, which was about four times higher than the national average. California had executed only 1 percent of those sentenced.

Problem: The major time divisions of classical music up to 1900 are the early music period, which includes Medieval (5001400) and Renaissance (14001600) eras, and the Common practice period, which includes the Baroque (16001750), Classical (17501830) and Romantic (18041910) eras. Since 1900, classical periods have been reckoned more by calendar century than by particular stylistic movements that have become fragmented and difficult to define. The 20th century calendar period (19012000) includes most of the early modern musical era (18901930), the entire high modern (mid 20th-century), and the first 25 years of the contemporary or postmodern musical era (1975current). The 21st century has so far been characterized by a continuation of the contemporary/postmodern musical era.
How have periods been reckoned Since 1900?

Problem: Al-Azhar University, founded in Cairo, Egypt in 975 by the Ismaili Shii Fatimid dynasty as a jamiah, had individual faculties for a theological seminary, Islamic law and jurisprudence, Arabic grammar, Islamic astronomy, early Islamic philosophy and logic in Islamic philosophy. The postgraduate doctorate in law was only obtained after "an oral examination to determine the originality of the candidate's theses", and to test the student's "ability to defend them against all objections, in disputations set up for the purpose." 'Abd al-Latif al-Baghdadi also delivered lectures on Islamic medicine at al-Azhar, while Maimonides delivered lectures on medicine and astronomy there during the time of Saladin. Another early jamiah was the Nizamiyah of Baghdad (founded 1091), which has been called the "largest university of the Medieval world." Mustansiriya University, established by the Abbasid caliph al-Mustansir in 1233, in addition to teaching the religious subjects, offered courses dealing with philosophy, mathematics and the natural sciences.
