When a group of people starts a company, the founders usually serve as sources both of funding and of skills in marketing, management, and technical matters. It is unlikely that a single individual can both provide adequate funding and be skilled in marketing, management, and technical matters. Ttherefore, companies founded by groups are more likely to succeed than companies founded by individuals. Which one of the following is an assumption required by the argument? ['Some founding members of successful companies can provide both funding and skills in marketing, management, or technical matters.', 'Founders of a new company can more easily acquire marketing and management abilities than technical abilities.', 'New companies are more likely to succeed when their founders can provide adequate funding and skills in marketing, management, and technical abilities than if they must secure funding or skills from nonfounders.', "A new company is more likely to succeed if every founding member contributes equally to the company's initial funding than if some members contribute more funds than others."]
