proper question: Why did the Navy give a speech in court? 
 disfluent question: How did no make that why did the Navy give a speech in court? 
 context: Some civil disobedience defendants choose to make a defiant speech, or a speech explaining their actions, in allocution. In U.S. v. Burgos-Andujar, a defendant who was involved in a movement to stop military exercises by trespassing on U.S. Navy property argued to the court in allocution that the ones who are violating the greater law are the members of the Navy. As a result, the judge increased her sentence from 40 to 60 days. This action was upheld because, according to the U.S. Court of Appeals for the First Circuit, her statement suggested a lack of remorse, an attempt to avoid responsibility for her actions, and even a likelihood of repeating her illegal actions. Some of the other allocution speeches given by the protesters complained about mistreatment from government officials.

proper question: Why are memory cells not considered adaptive? 
 disfluent question: What happens er uh why are memory cells not considered adaptive? 
 context: When B cells and T cells are activated and begin to replicate, some of their offspring become long-lived memory cells. Throughout the lifetime of an animal, these memory cells remember each specific pathogen encountered and can mount a strong response if the pathogen is detected again. This is adaptive because it occurs during the lifetime of an individual as an adaptation to infection with that pathogen and prepares the immune system for future challenges. Immunological memory can be in the form of either passive short-term memory or active long-term memory.
