1. 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.

2. Companies that offer “employer sponsored insurance” (ESI) pay a portion of employees’ health care costs. In the manufacturing sector last year, companies that offered ESI had worker absentee rates 22% lower, on average, than those at companies that did not offer ESI. If, on the basis of the evidence above, it is argued that ESI decreases worker absenteeism, which of the following, if true, would most seriously weaken that argument?

A Results similar to those cited for the manufacturing sector have been found in other sectors of the economy where ESI is offered.

B At companies that offer ESI, employees have access to preventative health care such as regular check-ups, routine laboratory tests, and nutrition counseling.

C Because initiating an ESI plan requires a lot of paperwork for the company, employees, and the insurance provider, doing so is complex and time-consuming.

D Many firms in the manufacturing sector have improved workplace safety and decreased the occurrence of on-the job injuries in the last five years, and most of these companies introduced ESI at the same time.

E In manufacturing firms where ESI is offered, the average productivity is 2% higher than it is in those firms where workers are not covered by an ESI plan.
