Jensen and Ling did not have to be in direct competition with each other; indeed, they did not even have to know the other business existed. Rather, this argument hinges on other important assumptions. Clearly, the most important assumption is a, that the business leader’s personality is the main factor in the business’s success or failure. The premises focus on the personality traits of Jensen and Ling and jump to the conclusion that their personalities made thedifference in their business success. Choice B is incorrect for the same reason; it also forms a logical link between the premises and the conclusion. Choices D and E are incorrect because they state assumptions that are essential in making this an apples-to-oranges comparison. Whatever their personality differences, this comparison does not work if Jensen and Ling were not similarly equipped (with education and experience) and in comparable businesses operating undercomparable circumstances
