Question

examine the public service ads. this first ad is from 1917. what is the main difference between these two public service ads? the older ad targets families, while the newer ad targets food manufacturers. the older ad appeals primarily to logic, while the newer ad appeals to emotion. the older ad focuses on all foods, while the newer ad focuses on a specific food. the older ad provides specific ideas, while the newer ad tells how to get more information.

Explanation:

The 1917 ad lists specific actions like buying with thought, using less wheat & meat etc. Since the newer ad is not shown, but based on the content of the 1917 ad, it provides concrete ideas. There is no indication of the target - audience being families or food manufacturers, no clear appeal to logic or emotion, and it doesn't compare the focus on all foods vs a specific food.

Answer:

The older ad provides specific ideas, while the newer ad tells how to get more information.
