Clark: Our local community theater often produces plays by critically acclaimed playwrights. In fact, the production director says that critical acclaim is one of the main factors considered in the selection of plays to perform. So, since my neighbor Michaela' s new play will be performed by the theater this season, she must be a critically acclaimed playwright. The reasoning in Clark's argument is most vulnerable to criticism on the grounds that the argument ['uses as evidence a source that there is reason to believe is unreliable', 'fails to consider that several different effects may be produced by a single cause', 'treats one main factor considered in the selection of plays to perform as though it were a condition that must be met in order for a play to be selected', "takes a condition necessary for a playwright's being critically acclaimed to be a condition sufficient for a playwright's being critically acclaimed"]
