Which of the following, if true, most seriously weakens the researcher's conclusion?


1)Holding the job of a corporate executive causes people to develop "take charge" personality traits.


2)When working on charitable or community projects, corporate executives often use their ability to make decisions and lead people to make those projects successful.


3)Some people who are not executives have stronger "take charge" personalities than some people who currently serve as corporate executives.


4)Many people who aspire to become executives exhibit different management styles in their current jobs.


5)The executives that the researcher studied were often unsuccessful when they tried to manage their family activities as they do their business activities.
