Answer:
a. The average age of the population in his community is high.
Step-by-step explanation:
As the average age of the population in his community is high, it is an opportunity for an entrepreneur who wishes to open a business providing "Fitness for Life" physical conditioning services (strength, balance, and flexibility training) in a city of 100,000 people because people will be more interested in the physical conditioning services and they will be attracted towards it as when the age rises, people become more interested in the health related activities, therefore, chances are very high that this will pose a serious and profitable opportunity for the entrepreneur in that particular city. He or she can definitely capture this opportunity very handsomely and profitably.
