Question: Education in Switzerland is very diverse because the constitution of Switzerland delegates the authority for the school system to the cantons. There are both public and private schools, including many private international schools. The minimum age for primary school is about six years in all cantons, but most cantons provide a free "children's school" starting at four or five years old. Primary school continues until grade four, five or six, depending on the school. Traditionally, the first foreign language in school was always one of the other national languages, although recently (2000) English was introduced first in a few cantons.
Is there an answer to this question: Who has authority of school systems in Switzerland?

Answer: the cantons


Question: The change in political structure led to the inevitable development of the peasant class or smerdy. The smerdy were free un-landed people that found work by labouring for wages on the manors which began to develop around 1031 as the verv' began to dominate socio-political structure. The smerdy were initially given equality in the Kievian law code, they were theoretically equal to the prince, so they enjoyed as much freedom as can be expected of manual labourers. However, in the 13th century they began to slowly lose their rights and became less equal in the eyes of the law.
Is there an answer to this question: When did wages on the manors develop?

Answer: 1031


Question: The connector construction always ensures that the external sheath on the plug makes contact with its counterpart in the receptacle before any of the four connectors within make electrical contact. The external metallic sheath is typically connected to system ground, thus dissipating damaging static charges. This enclosure design also provides a degree of protection from electromagnetic interference to the USB signal while it travels through the mated connector pair (the only location when the otherwise twisted data pair travels in parallel). In addition, because of the required sizes of the power and common connections, they are made after the system ground but before the data connections. This type of staged make-break timing allows for electrically safe hot-swapping.
Is there an answer to this question: Where is the external metallic sheet connected?

Answer: typically connected to system ground


Question: During the summers at Nohant, particularly in the years 1839–43, Chopin found quiet, productive days during which he composed many works, including his Polonaise in A-flat major, Op. 53.
