Context and question: While Göring was optimistic the Luftwaffe could prevail, Hitler was not. On 17 September he postponed Operation Sea Lion (as it turned out, indefinitely) rather than gamble Germany's newly gained military prestige on a risky cross-Channel operation, particularly in the face of a sceptical Joseph Stalin in the Soviet Union. In the last days of the battle, the bombers became lures in an attempt to draw the RAF into combat with German fighters. But their operations were to no avail; the worsening weather and unsustainable attrition in daylight gave the OKL an excuse to switch to night attacks on 7 October.
When did the OKL switch to night raids?
Answer: 7 October
Context and question: al-Qarawīyīn University in Fez, Morocco is recognised by many historians as the oldest degree-granting university in the world, having been founded in 859 by Fatima al-Fihri. While the madrasa college could also issue degrees at all levels, the jāmiʻahs (such as al-Qarawīyīn and al-Azhar University) differed in the sense that they were larger institutions, more universal in terms of their complete source of studies, had individual faculties for different subjects, and could house a number of mosques, madaris, and other institutions within them. Such an institution has thus been described as an "Islamic university".
What religious buildings were housed inside al-Qarawiyin University?
Answer:
mosques
