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.

Complete Question:

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?

 (A) Some breath freshening products are advertised to eliminate up to 30% of the bacteria from the tongue.

(B) Tongue scrapers have already been on the market for a number of years.

(C) Many dentists recommend regular flossing, and not the use of the tongue scraper, to combat bad breath.

(D) A recent survey shows that 94% of those who regularly purchase breath freshening products are aware of the effectiveness of the tongue scraper.

(E) Some people buy breath freshening products for reasons other than to fight bad breath.

Option D, A recent survey shows that 94% of those who regularly purchase breath freshening products are aware of the effectiveness of the tongue scraper.

Explanation:

The market analyst believes that as the efficacy of the tongue scraper becomes more commonly known, the demand for breath refreshers will decline.

To demonstrate that this reasoning is flawed, one of two hypotheses must be that customers are primarily interested in products which combat bad breath or do not know how effective a language scraper really is.

This argument weakens the claims by challenging one of the key premises in the argument: the efficacy of the tongue scraper is not known to people who use breathing soothing items. When 94% of those who eat Breath-Fresheners use the tongue scraper, and those customers continue to buy Breath-Fresheners items, only 6% of those who eat Breath-Fresheners will vote for a stop buying such goods after discovering the efficacy of the Tongue Scraper in reducing Breathlessness. Even though all six percent stopped shopping for the goods, the demand would hardly be shrinking dramatically.

you can lose ranking 2 ways.

1) you don't have enough points due to you expending them by asking questions/your answers are deleted.

2) your brainliest's expired. this means that brainliests, once they exceed the 30 day limit, expires. this is to ensure that you continue to contribute into the community at a constant rank if you want to continue to have/exceed the rank you have right now.

if you go to profile, and click "show more information" located on the bottom left of the box with your information (on top of the questions answered, questions asked, and friends), you will be given the following information (example):

member since : 02/13/2017, 18: 11

questions answered: 9741

questions asked: 162

no. of brainliest answers: 1575

brainliest answers in last 30 days: 10

warnings: 0 view

questions/answers reported: 2637

questions/answers incorrectly reported: 64

look at the "brainliest answers in the last 30 days". this is the one that will affect your rank other than your points. again, once your brainliest expires (was earned 31+ days ago), it will not be counted.
