[Q]: Passage: However, the classification of madaris as "universities" is disputed on the question of understanding of each institution on its own terms. In madaris, the ijāzahs were only issued in one field, the Islamic religious law of sharīʻah, and in no other field of learning. Other academic subjects, including the natural sciences, philosophy and literary studies, were only treated "ancillary" to the study of the Sharia. For example, a natural science like astronomy was only studied (if at all) to supply religious needs, like the time for prayer. This is why Ptolemaic astronomy was considered adequate, and is still taught in some modern day madaris. The Islamic law undergraduate degree from al-Azhar, the most prestigious madrasa, was traditionally granted without final examinations, but on the basis of the students' attentive attendance to courses. In contrast to the medieval doctorate which was granted by the collective authority of the faculty, the Islamic degree was not granted by the teacher to the pupil based on any formal criteria, but remained a "personal matter, the sole prerogative of the person bestowing it; no one could force him to give one". Question: What was the purpose of studying natural sciences in madaris?
[A]: supply religious needs


[Q]: Passage: Further problems hampered the Arctic project after the commencement of drilling in 2012, as Shell dealt with a series of issues that involved air permits, Coast Guard certification of a marine vessel and severe damage to essential oil-spill equipment. Additionally, difficult weather conditions resulted in the delay of drilling during mid-2012 and the already dire situation was exacerbated by the "Kulluk" incident at the end of the year. Royal Dutch Shell had invested nearly US$5 billion by this stage of the project. Question: What conditions caused the delay of drilling in mid-2012?
[A]: difficult weather


[Q]: Passage: Switzerland was the last Western republic to grant women the right to vote. Some Swiss cantons approved this in 1959, while at the federal level it was achieved in 1971 and, after resistance, in the last canton Appenzell Innerrhoden (one of only two remaining Landsgemeinde) in 1990. After obtaining suffrage at the federal level, women quickly rose in political significance, with the first woman on the seven member Federal Council executive being Elisabeth Kopp, who served from 1984–1989, and the first female president being Ruth Dreifuss in 1999. Question: When were Switzerland women granted the right to vote on a federal level?
