Randall would not say that a longitudinal design doesn't explain age change since that is the main advantage of using a longitudinal design. He might argue that it takes a long time, requires a lot of resources, may suffer from high attrition rates, and does not control for cohort effects, but he would not say that it doesn't explain age change.
