What part of the brain controls reasoning, language, and sensation?

• A. Frontal
• B. Parietal
• C. Cerebrum
• D. Temporal

Answer: (B)

Reasoning, language, and sensation are higher brain functions that are managed by the cerebrum. The cerebrum houses the lobes that handle these tasks: the frontal lobe drives reasoning and speech production, the temporal lobe handles language comprehension and memory, and the parietal lobe processes sensory information like touch and proprioception. Because the question asks for a single structure that covers all three areas, naming the cerebrum makes the most sense, since it contains all the involved lobes and integrates their functions. The parietal lobe focuses mainly on sensation, while the frontal and temporal lobes cover reasoning and language, but none of them alone accounts for all three together.
