Question

The Incandescent original fruit juice claims to be the most original fruit juice available on the market today. To prove this claim, the company marketing incandescent called 10 people and asked them about thoughts on fruit juices available on the market today. Nine of them stated that they unequivocally drink Incandescent brand fruit juices on a regular basis because it is closest to the taste of real fruits. Which of the following would most weaken this argument'?

• A. The Incandescent brand fruit juice is highly addictive.
• B. The 10 people called were related closely to top executives of the company.
• C. Most people prefer cola drinks to fruit juices. Here, Incandescent is a poor third to Coke and Pepsi.
• D. The 10 people were selected at random.
• E. All of these.

Answer 1

The correct option is B

The 10 people called were related closely to top executives of the company.

The claim made in the paragraph, is that the company fruit product is the most original and they invited 10 people to ask them their opinion. The study would have most detrimental effect if the study was not a double blind study and not properly controlled. Here in option (b) , it is given that, the 10 people were closely related to the top management leading to an implicit bias within them to favour a product over others. This seriously undermines the study; hence the answer is option (b).
