Question

Why are older adults more likely to forget what items they wanted to buy at a grocery store (unless they write them down on a list and take it with them) than they are to forget how to drive a car?
a. implicit memory is less likely to be adversely affected by aging than explicit memory.
b. perceptual speed declines with aging.
c. explicit memory declines more rapidly with aging than implicit memory.
d. source memory is more likely to decline with aging than prospective memory?

Answer 1

I believe the answer is: A.  implicit memory is less likely to be adversely affected by aging than explicit memory.

Implicit memory played a larger role in controlling every actions that we do in autopilot mode (without much focus). Such as driving a car, walking,brushing our teeths, etc. 
This type of memory is usually acquired over along period of  time so it much more harder to be erased in our memory even when we got older.
