The language production and comprehension centers are located in the left hemisphere in about % of the right-handed population.

The correct answer is 88%.

Studies shown that the language lateralization "typical" with a dominant left hemisphere are present in 88% of right-handers and 78% of left-handers. While the "ambilateral" or the ones without a clearly dominant hemisphere are present in 12% of right-handers and 15% of left-handers, and the "strongly atypical" with a dominant right hemisphere are present only in 7% of left-handers.

b - the respond is innate and varies over time.

good luck!
