Answer:
The cohort effect is a big problem for research in sociology and epidemiology, as well as in psychology because it´s a research outcome that has been influenced by the features of the cohort under study, given that they all share common historical and social experiences. The cohort effects are particularly problematic in cross-sectional methods.

However, the results could be tainted by the cohort effect in that putting together a puzzle is an activity that older participants are more likely to have done in the past, opposite to younger participants raised in a more technological time.
Well, think about it. Who wears a white coat? Scientists and doctors usually wear white coats and in the question, it says that they are advertising a health product! It matches together! Nina should conclude that the health product is most likely helpful and has a use, especially when a doctor or scientist is recommending it!
