He found a p relationship between hemisphere (26) and the way subjects made a (27) : left-brain-oriented subjects were more often lawyers, writers, bookkeepers, doctors, tax experts, etc. —jobs (28) with logical, language-related information. Those who favored the right hemisphere (29) out to be poets, politicians, musicians, architects, entrepreneurs, dancers and (30) —top executives.

Since "of" is pronounced "ov", the verbal left hemisphere took the verbal (44) and overrode the right, "seeing" hemisphere; (45) forcing the wrong conclusion.

A.facts

B.points

C.situations

D.chances
