question:
The geographical regions in which Iranian languages were spoken were pushed back in several areas by newly neighbouring languages. Arabic spread into some parts of Western Iran (Khuzestan), and Turkic languages spread through much of Central Asia, displacing various Iranian languages such as Sogdian and Bactrian in parts of what is today Turkmenistan, Uzbekistan and Tajikistan. In Eastern Europe, mostly comprising the territory of modern-day Ukraine, southern European Russia, and parts of the Balkans, the core region of the native Scythians, Sarmatians, and Alans had been decisively been taken over as a result of absorption and assimilation (e.g. Slavicisation) by the various Proto-Slavic population of the region, by the 6th century AD. This resulted in the displacement and extinction of the once predominant Scythian languages of the region. Sogdian's close relative Yaghnobi barely survives in a small area of the Zarafshan valley east of Samarkand, and Saka as Ossetic in the Caucasus, which is the sole remnant of the once predominant Scythian languages in Eastern Europe proper and large parts of the North Caucasus. Various small Iranian languages in the Pamirs survive that are derived from Eastern Iranian.

question:
Today, the system of Arabic and Islamic education has grown and further integrated with Kerala government administration. In 2005, an estimated 6,000 Muslim Arabic teachers taught in Kerala government schools, with over 500,000 Muslim students. State-appointed committees, not private mosques or religious scholars outside the government, determine the curriculum and accreditation of new schools and colleges. Primary education in Arabic and Islamic studies is available to Kerala Muslims almost entirely in after-school madrasa programs - sharply unlike full-time madaris common in north India, which may replace formal schooling. Arabic colleges (over eleven of which exist within the state-run University of Calicut and the Kannur University) provide B.A. and Masters' level degrees. At all levels, instruction is co-educational, with many women instructors and professors. Islamic education boards are independently run by the following organizations, accredited by the Kerala state government: Samastha Kerala Islamic Education Board, Kerala Nadvathul Mujahideen, Jamaat-e-Islami Hind, and Jamiat Ulema-e-Hind.
answer:
How many Muslim students are there in Kerala?
