Market Analyst: Recent research confirms that the main cause of bad breath is bacteria build-up on the tongue. The research also concludes that tongue scrapers, when used properly, can eliminate up to 40% of the bacteria from the tongue. As the effectiveness of tongue scrapers becomes more widely known, the market for less effective breath freshening products, such as mints, gums, and sprays, will decline significantly.
Which of the following provides the best evidence that the analyst’s argument is flawed?
Some breath freshening products are advertised to eliminate up to 30% of the bacteria from the tongue.
Tongue scrapers have already been on the market for a number of years.
Many dentists recommend regular flossing, and not the use of the tongue scraper, to combat bad breath.
A recent survey shows that 94% of those who regularly purchase breath freshening products are aware of the effectiveness of the tongue scraper.
Some people buy breath freshening products for reasons other than to fight bad breath.
OA is D , confused between a & d pls can somebody explain
