Official Solution:
After the new CEO took over the position at an automobile company, the color of the car seats was changed from their traditional white to only silver and gold. This shift from the heritage color, which had been a long-standing tradition of the company, drew criticism from many car magazine editors. They argued that the new CEO is more interested in boosting sales than in preserving the company's heritage.
Which of the following is a necessary assumption made by the editors in their criticism of the new CEO?
A. The shiny luster of silver and gold colored seats often attracts public attention, but does not entice them to buy the car.
B. It was the CEO who initiated the change in seat colors.
C. An automobile company can boost sales by using gray and crimson color seats.
D. The silver and gold colored seats are featured in the new international automobile expo.
E. Cars with silver and gold colored seats are purchased at a rate more than three times that for cars with the heritage white colored seats.
A. This option weakens the argument of the editors. If the new colors do not entice the public to buy the car, then the conclusion that the CEO’s interest is to boost the sales cannot be arrived at.
B. CORRECT. Premise: The color of the seats were changed after the new CEO joined.
Conclusion: The CEO is interested in boosting sales (by changing the color of the seats).
An assumption is necessarily new information that must be there to arrive from the premise to conclusion. In this passage nowhere it is mentioned that it is the CEO who wanted to change the seat color. However if one wants to arrive at the conclusion that the CEO was interested in boosting sales by changing the seat color, then it also must be assumed that the CEO himself must have intended to change the seat color. If someone else intended to change the seat color then the argument of the editors does not make sense.
C. The argument is concerned with cars with seat covers of gold and silver colors. Information about cars with seat covers of other colors is irrelevant.
D. The information that silver and gold coloured seat covers are featured in an expo is irrelevant.
E. The rate at which the cars with silver and gold coloured seats are purchased is not necessary to be assumed for the conclusion to be true.
