Answer:
True.
Step-by-step explanation:
Wernicke's area is the area in the brain that is responsible for developing language. Wernicke's area is located in the temporal lobe of the brain, that is, on the left side. Wernicke's aphasia is the disorder that happens to a person when Wernicke's area of the brain is damaged.
In this disorder, a person is able to speak fluently but in vague and meaningless phrases.
Wernicke's area was discovered by the neurologist whose name was Carl Wernicke. This area of the brain in the temporal lobe was then named after him as, Wernicke's area.
In the given case, Rosemary's area of the brain that is damaged is Wernicke's area; which has left her to speak fluently but in vague language.
