What is the meaning of the word deceptive as it is used in the fifth paragraph?
In the fifth paragraph, the word deceptive means “misleading.” The root of the word deceptive is the same as for the words deceive and deception. Take a look at the context in which the word is used. The author states that the FDA prevents certain kinds of advertising. It would be somewhat redundant for the author to mean that the FDA prevents illegal advertising; this goes without saying. At the same time, it is unlikely that the FDA spends its time trying to prevent merely irritating advertising; the persistent presence of such advertising makes this answer choice inappropriate. Left with a choice between malicious and misleading advertising, it makes better sense to choose the latter, since being mean and nasty would be a bad technique for selling a product. It is common, however, for an advertiser to deliberately mislead the consumer.
