Problem: These court categories were not, however, wholly exclusive: for instance, the Islamic courtswhich were the Empire's primary courtscould also be used to settle a trade conflict or disputes between litigants of differing religions, and Jews and Christians often went to them to obtain a more forceful ruling on an issue. The Ottoman state tended not to interfere with non-Muslim religious law systems, despite legally having a voice to do so through local governors. The Islamic Sharia law system had been developed from a combination of the Qur'an; the Hadith, or words of the prophet Muhammad; ijma', or consensus of the members of the Muslim community; qiyas, a system of analogical reasoning from earlier precedents; and local customs. Both systems were taught at the Empire's law schools, which were in Istanbul and Bursa.
From what works was Sharia developed?
The answer is the following: the Qur'an; the Hadith

Problem: Carnival has been celebrated for centuries. The tradition was likely established under Venetian rule around the 16th century. It may have been influenced by Greek traditions, such as festivities for deities such as Dionysus. The celebration originally involved dressing in costumes and holding masked balls or visiting friends. In the twentieth century it became an organized event held during the 10 days preceding Lent (according to the Greek Orthodox calendar). The festival is celebrated almost exclusively in the city of Limassol.
In what century did the Carnival become an organized event?
The answer is the following: twentieth

Problem: The city is roughly bisected by the North Canadian River (recently renamed the Oklahoma River inside city limits). The North Canadian once had sufficient flow to flood every year, wreaking destruction on surrounding areas, including the central business district and the original Oklahoma City Zoo. In the 1940s, a dam was built on the river to manage the flood control and reduced its level. In the 1990s, as part of the citywide revitalization project known as MAPS, the city built a series of low-water dams, returning water to the portion of the river flowing near downtown. The city has three large lakes: Lake Hefner and Lake Overholser, in the northwestern quarter of the city; and the largest, Lake Stanley Draper, in the sparsely populated far southeast portion of the city.
What was built in the 1990's to help return water to the river near downtown?
The answer is the following: low-water dams

Problem: The Houston area is a leading center for building oilfield equipment. Much of its success as a petrochemical complex is due to its busy ship channel, the Port of Houston. In the United States, the port ranks first in international commerce and tenth among the largest ports in the world. Unlike most places, high oil and gasoline prices are beneficial for Houston's economy, as many of its residents are employed in the energy industry. Houston is the beginning or end point of numerous oil, gas, and products pipelines:
Where does Houston rate in the size ranking of world ports?
The answer is the following:
tenth
