Did Beaver have the contractual capacity to enter a contract with an exculpatory clause? Why or why not?

Renee Beaver started racing go-karts competitively in 1997, when she was fourteen. Many of the races required her to sign an exculpatory clause to participate, which she or her parents regularly signed. In 2000, she participated in the annual Elkhart Grand Prix, a series of races in Elkhart, Indiana. During the event in which she drove, a piece of foam padding used as a course barrier was torn from its base and ended up on the track. A portion of the padding struck Beaver in the head, and another portion was thrown into oncoming traffic, causing a multikart collision during which she sustained severe injuries. Beaver filed an action against the race organizers for negligence. The organizers could not locate the exculpatory clause that Beaver was supposed to have signed. Race organizers argued that she must have signed one to enter the race, but even if she had not signed one, her actions showed her intent to be bound by its terms. Using the information presented in the chapter, answer the above question.
