Use the Passage Below to Answer the Following Questions

Use the passage below to answer the following questions.
Prior to 1997, broadcast ads for prescription drugs could not mention both the ailment for which the drug received FDA approval and the name of the drug in the same advertisement. That is, only one or the other could be mentioned, which led to much confusion on the part of consumers. In 1997, the Food and Drug Administration loosened its controls on pharmaceutical companies, and as a result, the amount of prescription drug advertising on television has skyrocketed. Now both the ailment and the name of the drug can be mentioned, but major side effects must also be mentioned and there must be an indication where the consumer can get more information, such as from a magazine ad or a website. Some have been quite critical of this direct-to-consumer prescription advertising, claiming it has led to an increase in requests for costlier drugs when the less expensive generic drugs would be just as effective.
-Although some doctors appreciate that the advertising has caused consumers to become more active in managing their own health and more informed about their drug options,some claim that they are being pressured to write inappropriate prescriptions because their patients are influenced by the drug ad claims.What is this called,when an external message,like an advertisement,causes people to feel a need to buy and use a product?

A) demand creation
B) shockvertising
C) indirect advertising
D) endorsement advertising
E) puffery
