Fraenger' s assertion that the artist Hieronymus Bosch belonged to the Brethren of the Free Spirit, a nonmainstream religious group, is unlikely to be correct. Fraenger' s hypothesis explains much of Bosch' s unusual subject matter. However, there is evidence that Bosch was a member of a mainstream church, and no evidence that he was a member of the Brethren. The statement that there is no evidence that Bosch was a member of the Brethren figures in the argument in which one of the following ways? ["It is used to dispute Fraenger's hypothesis by questioning Fraenger's credibility.", "It is intended to help show that Bosch's choice of subject matter remains unexplained.", "It is intended to cast doubt on Fraenger's hypothesis by questioning the sufficiency of Fraenger's evidence.", "It is a premise that, when combined with the other premises, guarantees the falsity of Fraenger's assertion."]
