Solve the following mini-mysteries on your own using your own native reasoning abilities, and then based on what you have learned, explain how you know deductive rather than inductive reasoning is used in each case. 
1.Either Moriarty was the murderer, or Stapleton was the murderer. If Stapleton was the murderer, then traces of phosphorus should have been found on the body. No traces of phosphorus were found on the body. Whodunnit?
2.The murder did not occur in the library. If Adler was the murderer, then the weapon was a revolver. Either Hope was the murderer, or Adler was the murderer. If Hope was the murderer, then the murder took place in the library. Whodunnit? With what weapon?
3. The murder was not committed on the moor. If Windibank was the murderer, then the weapon was a rope. Either Windibank was the murderer, or Calhoun was the murderer. If the weapon was a rope, then the murder was committed on the downs. If Calhoun was the murderer, then the weapon was a crowbar. If the weapon was a crowbar, then the murder was committed on the moor. Whodunnit? With what weapon? Where was the murder committed?
