Example Input: proper question: What type of outlook do some of the non-Muslims in London have?
disfluent question: How many er what type of outlook do some of the non-Muslims in London have?
context: Greater London has over 900,000 Muslims, (most of South Asian origins and concentrated in the East London boroughs of Newham, Tower Hamlets and Waltham Forest), and among them are some with a strong Islamist outlook. Their presence, combined with a perceived British policy of allowing them free rein, heightened by exposes such as the 2007 Channel 4 documentary programme Undercover Mosque, has given rise to the term Londonistan. Following the 9/11 attacks, however, Abu Hamza al-Masri, the imam of the Finsbury Park Mosque, was arrested and charged with incitement to terrorism which has caused many Islamists to leave the UK to avoid internment.[citation needed]
Example Output: None

Example Input: proper question: What is the full name of the ASER?
disfluent question: Which is no uh make that what is the full name of the ASER?
context: Legally, only non-profit trusts and societies can run schools in India. They will have to satisfy a number of infrastructure and human resource related criteria to get Recognition (a form of license) from the government. Critics of this system point out that this leads to corruption by school inspectors who check compliance and to fewer schools in a country that has the largest adult illiterate population in the world. While official data does not capture the real extent of private schooling in the country, various studies have reported unpopularity of government schools and an increasing number of private schools. The Annual Status of Education Report (ASER), which evaluates learning levels in rural India, has been reporting poorer academic achievement in government schools than in private schools. A key difference between the government and private schools is that the medium of education in private schools is English while it is the local language in government schools.
Example Output: Annual Status of Education Report

Example Input: proper question: During what word was Jacksonville a key supply point for the North?
disfluent question: During what word was Jacksonville a key supply point for the south no I meant the North?
context: During the American Civil War, Jacksonville was a key supply point for hogs and cattle being shipped from Florida to aid the Confederate cause. The city was blockaded by Union forces, who gained control of the nearby Fort Clinch. Though no battles were fought in Jacksonville proper, the city changed hands several times between Union and Confederate forces. The Skirmish of the Brick Church in 1862 just outside Jacksonville proper resulted in the first Confederate victory in Florida. In February 1864 Union forces left Jacksonville and confronted a Confederate Army at the Battle of Olustee resulting in a Confederate victory. Union forces then retreated to Jacksonville and held the city for the remainder of the war. In March 1864 a Confederate cavalry confronted a Union expedition resulting in the Battle of Cedar Creek. Warfare and the long occupation left the city disrupted after the war.
