Input: Consider Input: proper question: Who created ARPANET in the United States? 
 disfluent question: Who created RAND er uh ARPANET in the United States? 
 context: Starting in the late 1950s, American computer scientist Paul Baran developed the concept Distributed Adaptive Message Block Switching with the goal to provide a fault-tolerant, efficient routing method for telecommunication messages as part of a research program at the RAND Corporation, funded by the US Department of Defense. This concept contrasted and contradicted the theretofore established principles of pre-allocation of network bandwidth, largely fortified by the development of telecommunications in the Bell System. The new concept found little resonance among network implementers until the independent work of Donald Davies at the National Physical Laboratory (United Kingdom) (NPL) in the late 1960s. Davies is credited with coining the modern name packet switching and inspiring numerous packet switching networks in Europe in the decade following, including the incorporation of the concept in the early ARPANET in the United States.

Input: Consider Input: proper question: What political response was convening in June/July 1745? 
 disfluent question: What unified response, no sorry sorry, political response was convening in June/July 1745? 
 context: An early important political response to the opening of hostilities was the convening of the Albany Congress in June and July, 1754. The goal of the congress was to formalize a unified front in trade and negotiations with various Indians, since allegiance of the various tribes and nations was seen to be pivotal in the success in the war that was unfolding. The plan that the delegates agreed to was never ratified by the colonial legislatures nor approved of by the crown. Nevertheless, the format of the congress and many specifics of the plan became the prototype for confederation during the War of Independence.

Input: Consider Input: proper question: How is course content provided to a private school? 
 disfluent question: What amendment to the United States Constitution no scratch that how is course content provided to a private school? 
 context: Funding for private schools is generally provided through student tuition, endowments, scholarship/voucher funds, and donations and grants from religious organizations or private individuals. Government funding for religious schools is either subject to restrictions or possibly forbidden, according to the courts' interpretation of the Establishment Clause of the First Amendment or individual state Blaine Amendments. Non-religious private schools theoretically could qualify for such funding without hassle, preferring the advantages of independent control of their student admissions and course content instead of the public funding they could get with charter status.
