Use a disfluent question or a proper question and find the answer to the question based on the given context or return None if an answer can't be found. A disfluent question is a question that has some interruptions in it while framing. A proper question is the correct form of the question without any disfluency.

Question: proper question: What is the crystal lattice made out of? 
 disfluent question: What determines no i meant to say what is the crystal lattice made out of? 
 context: For many geologic applications, isotope ratios of radioactive elements are measured in minerals that give the amount of time that has passed since a rock passed through its particular closure temperature, the point at which different radiometric isotopes stop diffusing into and out of the crystal lattice. These are used in geochronologic and thermochronologic studies. Common methods include uranium-lead dating, potassium-argon dating, argon-argon dating and uranium-thorium dating. These methods are used for a variety of applications. Dating of lava and volcanic ash layers found within a stratigraphic sequence can provide absolute age data for sedimentary rock units which do not contain radioactive isotopes and calibrate relative dating techniques. These methods can also be used to determine ages of pluton emplacement. Thermochemical techniques can be used to determine temperature profiles within the crust, the uplift of mountain ranges, and paleotopography.

Answer: None


Question: proper question: Where was French advance to? 
 disfluent question: Who won or uh where was French advance to? 
 context: Johnson's expedition was better organized than Shirley's, which was noticed by New France's governor, the Marquis de Vaudreuil. He had primarily been concerned about the extended supply line to the forts on the Ohio, and had sent Baron Dieskau to lead the defenses at Frontenac against Shirley's expected attack. When Johnson was seen as the larger threat, Vaudreuil sent Dieskau to Fort St. Frédéric to meet that threat. Dieskau planned to attack the British encampment at Fort Edward at the upper end of navigation on the Hudson River, but Johnson had strongly fortified it, and Dieskau's Indian support was reluctant to attack. The two forces finally met in the bloody Battle of Lake George between Fort Edward and Fort William Henry. The battle ended inconclusively, with both sides withdrawing from the field. Johnson's advance stopped at Fort William Henry, and the French withdrew to Ticonderoga Point, where they began the construction of Fort Carillon (later renamed Fort Ticonderoga after British capture in 1759).

Answer: None


Question: proper question: At what level are 13% of children in Scottish independent schools? 
 disfluent question: At what level are 13% of children in Scottish public schools, no make that, in independent schools? 
 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.

None
