A 45-year-old man on the neurology floor can understand instructions but is unable to express himself through talking. Which lobe of the brain controls the expression of speech?
Frontal lobe
Occipital lobe
Temporal lobe
Parietal lobe
The Correct Answer is A

Choice D rationale: The parietal lobe is involved in spatial perception, attention, and sensory information processing.
