"What will be the results if two monopolistic competitors both launch successful advertising campaigns targeting its competitors consumers in order to draw them away from the other firm

a. These two competitor firms will negate each other's efforts.

Explanation:

The advertising campaigns that both monopolistic competitors was said to be successful which means that they were both able to draw their competitor's customers away from the other firm.

The net effect of this would be that both of them negated each other's efforts because when Firm A gained some of Firm B's customers it also lost some of its customers to Firm B which is evidently also what happened to Firm B.

the answer is b for dog

there was no passage listed but using the process of elimination i'd say it was d. the high economy would do the opposite. i don't see how low prices would affect it. high unemployment is possible but i feel d is the better answer.
