Ibn Sina refers to the secondary education stage of maktab schooling as a period of specialisation when pupils should begin to acquire manual skills, regardless of their social status. He writes that children after the age of 14 should be allowed to choose and specialise in subjects they have an interest in, whether it was reading, manual skills, literature, preaching, medicine, geometry, trade and commerce, craftsmanship, or any other subject or profession they would be interested in pursuing for a future career. He wrote that this was a transitional stage and that there needs to be flexibility regarding the age in which pupils graduate, as the student's emotional development and chosen subjects need to be taken into account.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): According to Ibn Sina, what is needed to support transition at the secondary stage of education?
Ah, so.. flexibility

Between two thirds and three quarters of the population live in urban areas. Switzerland has gone from a largely rural country to an urban one in just 70 years. Since 1935 urban development has claimed as much of the Swiss landscape as it did during the previous 2,000 years. This urban sprawl does not only affect the plateau but also the Jura and the Alpine foothills and there are growing concerns about land use. However, from the beginning of the 21st century, the population growth in urban areas is higher than in the countryside.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): From the beginning of the 21st century, how does the population growth in urban areas compare to the countryside?
Ah, so.. higher
