When a person with temporal lobe epilepsy is having an epileptic seizure, part of the brain’s temporal lobe produces abnormal electrical impulses, which can often, but not always, be detected through a test called an electroencephalogram (EEG). Therefore, although a positive EEG reading—that is, evidence of abnormal electrical impulses—during an apparent seizure is a reasonably reliable indicator of temporal lobe epilepsy, ______
Of the following, which one logically completes the conclusion above?
(A) a positive reading is just as reliable an indicator of the absence of temporal lobe epilepsy
(B) a positive reading can also indicate the presence of other forms of epilepsy
(C) a positive reading is more frequently an erroneous reading than is a negative one
(D) a negative reading does not mean that temporal lobe epilepsy can be ruled out
(E) a negative reading is just as reliable an indicator of the presence of temporal lobe epilepsy
