Answer:
This case involves a federal death sentence imposed on defendant-appellant Fields for conviction of a federal capital offense. Fields was sentenced to death largely on the basis of the opinion of a psychiatrist who stated that he could confidently predict Fields would be dangerous in the future. The psychiatrist testified that he did not know of any "standard psychiatric or medical procedures used in arriving at a determination or predicting future dangerousness" and that he was unaware of specific empirical data or studies. He issued his opinion without engaging in any testing or any other objective measures or use of an actuarial method. His basis for this opinion was discussions with the prosecutors and review of some records regarding the defendant. The defense attorney objected to the testimony as unreliable under the standards for expert testimony established by the U.S. Supreme Court in Daubert v. Merrill Dow Pharmaceutical (i.e., that proffered evidence must be grounded in scientific reasoning or methodology). The district court overruled the objections and allowed the expert testimony to go to the jury.

Answer: Well, Humanity's early fire-starting tools may have been dangerous because in the text is says, "It could be lighted only by hard rubbing, and it sputtered and threw fire in all directions." This is dangerous because it would spew fire in all directions and if you think about it, the fire would hit something and then that thing would catch on fire. Lets say you were using the match inside your house. When you strike the match, a spark flies onto the wood floor and your house goes up in flames and you are stuck inside the house with no exit or escape. This may or may not happen, but because of the fire not being contained, there was a chance that you would be harmed.
