Answer to Question 1

F

Answer to Question 2

Answer should include points such as the following:
 The most popular approach to collecting gunshot residues from a shooter's hands involves applying adhesive tape or adhesive to the hand's surface to remove any adhering residue particles.
 Another approach is to remove any residues present by swabbing both the firing and nonfiring hands with cotton that has been moistened with 5 percent nitric acid. The front and back of each hand are separately swabbed. All four swabs, along with a moistened control, are then forwarded to the crime laboratory for analysis.
The most specific analysis method for these collected samples is by SEM coupled with an X-ray analyzer to determine elemental components of the residue.
