B) right-handers are more likely to be left-hemisphere dominant for speech than right-hemisphere dominant for speech.

Question

Quizplus · Accepted Answer

Sodium amytal tests have consistently shown that left-handed individuals have a more variable distribution of cerebral dominance for speech compared to right-handed individuals. This supports option A. Additionally, right-handers are more likely to have left-hemisphere dominance for speech, which supports option B. Therefore, both A and B are correct, and the best choice is E. Option C is not supported by sodium amytal tests, as left-handers are still more likely to have left-hemisphere dominance for speech compared to right-hemisphere dominance. Option D is incorrect, as option C is not supported by the evidence.
