Answer:
The correct answer for: What fMRI-measured brain activity would be expected in a subject witnessing a high-content argument? is: A. The frontal lobes in high-motivation, high-knowledge people are more active than the temporal lobes in low-motivation, low-content people.
Explanation:
First of all, this is a very difficult question because the answers are focused on the excitement of the subjects. When fMRIbrain activity is measured in a subject witnessing high-content arguments the frontal lobe will activate in high motivation high knowledge people. While the temporal lobe will activate in low motivation, low content people. So the frontal lobes will show more activity because they are going to be stimulated while the temporal lobe won't, making the stimulation a determining factor of the level of activity in the brain.
