[EX Q]: proper question: What does extension do to sediment that is less than a meter long? 
 disfluent question: Where does or rather what does extension do to sediment that is less than a meter long? 
 context: Extension causes the rock units as a whole to become longer and thinner. This is primarily accomplished through normal faulting and through the ductile stretching and thinning. Normal faults drop rock units that are higher below those that are lower. This typically results in younger units being placed below older units. Stretching of units can result in their thinning; in fact, there is a location within the Maria Fold and Thrust Belt in which the entire sedimentary sequence of the Grand Canyon can be seen over a length of less than a meter. Rocks at the depth to be ductilely stretched are often also metamorphosed. These stretched rocks can also pinch into lenses, known as boudins, after the French word for sausage, because of their visual similarity.

[EX Q]: proper question: What is the highest range a student would pay when boarding  in a Scottish school? 
 disfluent question: What is the highest range a school charges no um sorry a student would pay when boarding in a Scottish school? 
 context: Private schools generally prefer to be called independent schools, because of their freedom to operate outside of government and local government control. Some of these are also known as public schools. Preparatory schools in the UK prepare pupils aged up to 13 years old to enter public schools. The name public school is based on the fact that the schools were open to pupils from anywhere, and not merely to those from a certain locality, and of any religion or occupation. According to The Good Schools Guide approximately 9 per cent of children being educated in the UK are doing so at fee-paying schools at GSCE level and 13 per cent at A-level.[citation needed] Many independent schools are single-sex (though this is becoming less common). Fees range from under £3,000 to £21,000 and above per year for day pupils, rising to £27,000+ per year for boarders. For details in Scotland, see Meeting the Cost.

 disfluent question: Who distributes um i mean who is not required to follow financial rules and regulations? 
 context: The IPCC receives funding through the IPCC Trust Fund, established in 1989 by the United Nations Environment Programme (UNEP) and the World Meteorological Organization (WMO), Costs of the Secretary and of housing the secretariat are provided by the WMO, while UNEP meets the cost of the Depute Secretary. Annual cash contributions to the Trust Fund are made by the WMO, by UNEP, and by IPCC Members; the scale of payments is determined by the IPCC Panel, which is also responsible for considering and adopting by consensus the annual budget. The organisation is required to comply with the Financial Regulations and Rules of the WMO.
