Problem: Early-years education is quite common in Thuringia. Since the 1950s, nearly all children have been using the service, whereas early-years education is less developed in western Germany. Its inventor Friedrich Fröbel lived in Thuringia and founded the world's first Kindergartens there in the 19th century. The Thuringian primary school takes four years and most primary schools are all-day schools offering optional extracurricular activities in the afternoon. At the age of ten, pupils are separated according to aptitude and proceed to either the Gymnasium or the Regelschule. The former leads to the Abitur exam after a further eight years and prepares for higher education, while the latter has a more vocational focus and finishes with exams after five or six years, comparable to the Hauptschule and Realschule found elsewhere in Germany.
When do children graduate from primary school in Thuringia?

Answer: At the age of ten

Question: Until the 19th century, religion played a significant role in university curriculum; however, the role of religion in research universities decreased in the 19th century, and by the end of the 19th century, the German university model had spread around the world. Universities concentrated on science in the 19th and 20th centuries and became increasingly accessible to the masses. In Britain, the move from Industrial Revolution to modernity saw the arrival of new civic universities with an emphasis on science and engineering, a movement initiated in 1960 by Sir Keith Murray (chairman of the University Grants Committee) and Sir Samuel Curran, with the formation of the University of Strathclyde. The British also established universities worldwide, and higher education became available to the masses not only in Europe.
