Question
In its latest advertisement, PureSip Mineral Water
claims that its product is the healthiest bottled water available in the market. The company states that since PureSip water undergoes a special triple-filtration process that removes all minerals and impurities, it is safer and purer than ordinary bottled water. Therefore, people who drink PureSip regularly are likely to be healthier than others. Which of the following, if true, would most seriously weaken the argument made by PureSip?Solution
The advertisement’s argument is: Premise: PureSip removes all minerals and impurities. Conclusion: Therefore, it is the healthiest water and makes people healthier. If essential minerals (like calcium, magnesium, etc.) are also removed in this process, the argument collapses — because what PureSip presents as a benefit (removing everything) actually reduces the water’s health value. Hence, option B most strongly weakens the argument.
