This sentence makes a statement about evidence of Americans' growing social isolation. The structure of the sentence indicates that the part following the colon consists of examples of such "evidence," so the correct answer choices must characterize the evidence in a way that corresponds to the examples listed. This requirement eliminates "indecipherable" and "unfathomable," since the examples are easy to comprehend. Likewise, the examples are not "ambiguous" or "indefinite."
