Final answer:
Jennifer likely sustained damage to Wernicke's area, resulting in receptive aphasia, which impairs her ability to comprehend language.
Step-by-step explanation:
Jennifer probably experienced damage to the Wernicke's area, which is responsible for the comprehension of language. This type of impairment is known as receptive aphasia, a condition where individuals can produce words but have lost the ability to understand received language, such as what is spoken to them or given in written form. The Wernicke's area is located in the temporal lobe of the brain, and damage to this region can significantly affect language comprehension abilities.
