In studies of adult development and older
adulthood, the participants who do not come back for
further testing tend to be sicker, have lower education,

results 5 years later. Which conclusion would be
correct?
A. Our results apply to healthy older adults
B. Our results are from a good representation of all older adults
C. Our results apply to sicker older adults
A. our results apply to healthy older adults
