Answer to Question 1

ANS: B
Otherwise, the porous diffusing element may become occluded. Although complete blockage is unlikely, occlusion of the diffusing element can impair humidification and alter flow.

Answer to Question 2

ANS: B
Because the mineral content of tap water may be high (hard water), water used in these humidi-fiers should be distilled.
