Answer:
a. the advertisements wasted money and time because they were not targeted properly
Explanation:
The advertisement is not well targeted, with the increased unemployment in this region and the fact that the major source of economic wealth ( the beer manufacturer) has been bought and relocated, means the economy is not well profiled for the luxury cars that are advertised.
The company should first of all do it's research to gauge how well profiled the residents of the economy is to their products.
Ideally the target if the advertisement should be a thriving economy where there is excess cash to purchase luxury goods.
