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. Herrmann’s studies showed that the most successful people in any (31) are those who use both the left and right brains.
One test for hemisphere dominance is to (32) how you turn your head and eyes when (33) questions asked by someone in front of you. Research suggests that if you generally turn to the left, you have a right-brain (34) ; if you turn to the right, (35) are you prefer work that (36) use of logic or language.
Another test for dominance involves directions for (37) a product. A left-hemisphere- oriented person usually follows instructions in a step-by-step (38) —from written sentence to written sentence. Someone with p right-side input will probably (39) the written directions and assemble the pieces by (40) the diagram or picture.

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