Answer to Question 1

B
The RDA is the average needs of 98 of the population, not the exact needs of an individual. The tolerable upper intake level (UL) is the highest level that likely poses no risk for adverse health events. It is not a recommended level of intake.

Answer to Question 2

C
Hearing changes often associated with aging include decreased hearing acuity, speech intelligi-bility, and pitch discrimination, which is referred to as presbycusis. Low-pitched sounds are eas-iest to hear, but it is difficult to hear conversation over background noise. A decrease in active sebaceous glands causes the cerumen to become dry and completely obstruct the external audi-tory canal.
