Answer to Question 1

ANS: C
The minimal risk that may be present can be further reduced by maintaining high relative humid-ity (>60).

Answer to Question 2

ANS: B
Although O2 is nonflammable, it greatly accelerates the rate of combustion. Burning speed in-creases with an increase in either the concentration or partial pressure of O2.
