Task: Question Generation
Input (English): Haredi Judaism advocates segregation from non-Jewish culture, although not from non-Jewish society entirely. It is characterised by its focus on community-wide Torah study. Haredi Orthodoxy's differences with Modern Orthodoxy usually lie in interpretation of the nature of traditional halakhic concepts and in acceptable application of these concepts. Thus, engaging in the commercial world is a legitimate means to achieving a livelihood, but individuals should participate in modern society as little as possible. The same outlook is applied with regard to obtaining degrees necessary to enter one's intended profession: where tolerated in the Haredi society, attending secular institutions of higher education is viewed as a necessary but inferior activity. Academic interest is instead to be directed toward the religious education found in the yeshiva. Both boys and girls attend school and may proceed to higher Torah study, starting anywhere between the ages of 13 and 18. A significant proportion of students, especially boys, remain in yeshiva until marriage (which is often arranged through facilitated dating – see shiduch), and many study in a kollel (Torah study institute for married men) for many years after marriage. Most Orthodox men (including many Modern Orthodox), even those not in Kollel, will study Torah daily.
Output (English): What do a significant portion of boys remain in until marriage?
