Answer: The correct answer is : 1. Wernicke's area is involved in hearing; Broca's area is used for speech.
Explanation: Broca's area is in the left hemisphere and is responsible for producing language. Wernicke's area is in the left hemisphere and is responsible for sound compression. These two areas are connected through a group of nerve fibers called the acheated bundle. Our brain deals first with grammar and then with the semantic content of the sentences we hear.
