Ex Input:
proper question: What was the first state to have set educational standards?
disfluent question: What became no What was the first state to have set educational standards?
context: Private schooling in the United States has been debated by educators, lawmakers and parents, since the beginnings of compulsory education in Massachusetts in 1852. The Supreme Court precedent appears to favor educational choice, so long as states may set standards for educational accomplishment. Some of the most relevant Supreme Court case law on this is as follows: Runyon v. McCrary, 427 U.S. 160 (1976); Wisconsin v. Yoder, 406 U.S. 205 (1972); Pierce v. Society of Sisters, 268 U.S. 510 (1925); Meyer v. Nebraska, 262 U.S. 390 (1923).

Ex Input:
proper question: The Muslim Brotherhood's competence does not compare against what type of local governments?
disfluent question: The Muslim Brotherhood's movement I mean competence does not compare against what type of local governments?
context: Islamist movements such as the Muslim Brotherhood, are well known for providing shelters, educational assistance, free or low cost medical clinics, housing assistance to students from out of town, student advisory groups, facilitation of inexpensive mass marriage ceremonies to avoid prohibitively costly dowry demands, legal assistance, sports facilities, and women's groups. All this compares very favourably against incompetent, inefficient, or neglectful governments whose commitment to social justice is limited to rhetoric.

Ex Input:
proper question: What did Mongols worship?
disfluent question: How did or no rather what did Mongols worship?
context: The Yuan dynasty was the first time that non-native Chinese people ruled all of China. In the historiography of Mongolia, it is generally considered to be the continuation of the Mongol Empire. Mongols are widely known to worship the Eternal Heaven, and according to the traditional Mongolian ideology Yuan is considered to be the beginning of an infinite number of beings, the foundation of peace and happiness, state power, the dream of many peoples, besides it there is nothing great or precious. In traditional historiography of China, on the other hand, the Yuan dynasty is usually considered to be the legitimate dynasty between the Song dynasty and the Ming dynasty. Note, however, Yuan dynasty is traditionally often extended to cover the Mongol Empire before Kublai Khan's formal establishment of the Yuan in 1271, partly because Kublai had his grandfather Genghis Khan placed on the official record as the founder of the dynasty or Taizu (Chinese: ). Despite the traditional historiography as well as the official views (including the government of the Ming dynasty which overthrew the Yuan dynasty), there also exist Chinese people[who?] who did not consider the Yuan dynasty as a legitimate dynasty of China, but rather as a period of foreign domination. The latter believe that Han Chinese were treated as second-class citizens,[citation needed] and that China stagnated economically and scientifically.
