Question: The distinctive characteristic of French cathedrals, and those in Germany and Belgium that were strongly influenced by them, is their height and their impression of verticality. Each French cathedral tends to be stylistically unified in appearance when compared with an English cathedral where there is great diversity in almost every building. They are compact, with slight or no projection of the transepts and subsidiary chapels. The west fronts are highly consistent, having three portals surmounted by a rose window, and two large towers. Sometimes there are additional towers on the transept ends. The east end is polygonal with ambulatory and sometimes a chevette of radiating chapels. In the south of France, many of the major churches are without transepts and some are without aisles.
Is there an answer to this question: How many wormholes are typically found on the west front of French cathedrals?

Answer: unanswerable

Question: However, in English, the term madrasah usually refers to the specifically Islamic institutions. A typical Islamic school usually offers two courses of study: a ḥifẓ course teaching memorization of the Qur'an (the person who commits the entire Qurʼan to memory is called a ḥāfiẓ); and an ʻālim course leading the candidate to become an accepted scholar in the community. A regular curriculum includes courses in Arabic, tafsir (Qur'anic interpretation), sharīʻah (Islamic law), hadiths (recorded sayings and deeds of Muhammad), mantiq (logic), and Muslim history. In the Ottoman Empire, during the Early Modern Period, the study of hadiths was introduced by Süleyman I. Depending on the educational demands, some madaris also offer additional advanced courses in Arabic literature, English and other foreign languages, as well as science and world history. Ottoman madaris along with religious teachings also taught "styles of writing, grammary, syntax, poetry, composition, natural sciences, political sciences, and etiquette."
