Explanation:

Cohort studies can also be used to assess the risks and benefits of using a particular medication.
In the case of the research exposed in the question, one researcher analyzed the city's records to see who among the city's retirees had spent their careers working mostly indoors, without sun exposure; and outdoors with sun exposure. The sun is a major cause of hair cancer. Once participants were enrolled and screened, the scientist researched and examined the incidence of any form of skin cancer. This is a perfect example of a retrospective cohort study.
