Jason fell of his bicycle and hit his head against the pavement when he was six years old. though the doctors did their best to repair any brain damage he incurred, jason sustained severe injuries that left him unable to understand language. jason is able to speak, but his sentences make no sense and do not aid communication. from the information provided in the scenario, we can infer that the brain damage jason suffered affected his

Cerebral cortex.

Explanation:

The cerebral cortex is the structure that contains the cell bodies of neurons, where nerve impulses arrive, which are processed and "returned" with a response to the body. This part of the brain has several subdivisions, each of which has its own specialty and responsibility within the organism. One of these subdivisions is called "speech center", it is in this subdivision that speech processes and articulation of the sound of words are produced.

Because of this, if Jason has difficulty speaking and forming coherent sentences, we can conclude that he must have damage to the cerebral cortex in the region of the speech center.
