Like a genetic profile, a functional magnetic-resonance image (fMRI) of the brain can contain information that a patient wishes to keep private. An fMRI of a brain also contains enough information about a patient' s skull to create a recognizable image of that patient' s face. A genetic profile can be linked to a patient only by referring to labels or records. The statements above, if true, most strongly support which one of the following? ['Patients are more concerned about threats to privacy posed by fMRIs than they are about those posed by genetic profiles.', 'In most cases patients cannot be reasonably sure that the information in a genetic profile will be kept private.', "It is not important that medical providers apply labels to fMRIs of patients' brains.", 'An fMRI has the potential to compromise patient privacy in circumstances in which a genetic profile would not.']
