[Q]: proper question: What does non-revolutionary civil disobedience want to overthrow? 
 disfluent question: What type er what does non-revolutionary civil disobedience want to overthrow? 
 context: Non-revolutionary civil disobedience is a simple disobedience of laws on the grounds that they are judged wrong by an individual conscience, or as part of an effort to render certain laws ineffective, to cause their repeal, or to exert pressure to get one's political wishes on some other issue. Revolutionary civil disobedience is more of an active attempt to overthrow a government (or to change cultural traditions, social customs, religious beliefs, etc...revolution doesn't have to be political, i.e. cultural revolution, it simply implies sweeping and widespread change to a section of the social fabric). Gandhi's acts have been described as revolutionary civil disobedience. It has been claimed that the Hungarians under Ferenc Deák directed revolutionary civil disobedience against the Austrian government. Thoreau also wrote of civil disobedience accomplishing peaceable revolution. Howard Zinn, Harvey Wheeler, and others have identified the right espoused in The Declaration of Independence to alter or abolish an unjust government to be a principle of civil disobedience.

[Q]: proper question: What was the topic of the error? 
 disfluent question: Who or rather what was the topic of the error? 
 context: Former IPCC chairman Robert Watson has said The mistakes all appear to have gone in the direction of making it seem like climate change is more serious by overstating the impact. That is worrying. The IPCC needs to look at this trend in the errors and ask why it happened. Martin Parry, a climate expert who had been co-chair of the IPCC working group II, said that What began with a single unfortunate error over Himalayan glaciers has become a clamour without substance and the IPCC had investigated the other alleged mistakes, which were generally unfounded and also marginal to the assessment.

[Q]: proper question: How many types of cilia are there? 
 disfluent question: How many bands err I mean types of cilia are there? 
 context: Ranging from about 1 millimeter (0.039 in) to 1.5 meters (4.9 ft) in size, ctenophores are the largest non-colonial animals that use cilia (hairs) as their main method of locomotion. Most species have eight strips, called comb rows, that run the length of their bodies and bear comb-like bands of cilia, called ctenes, stacked along the comb rows so that when the cilia beat, those of each comb touch the comb below. The name ctenophora means comb-bearing, from the Greek κτείς (stem-form κτεν-) meaning comb and the Greek suffix -φορος meaning carrying.
