Final answer:
Damage to the left frontal lobe can result in difficulty speaking meaningful sentences, a condition known as Broca's aphasia.
Step-by-step explanation:
When a person has difficulty speaking meaningful sentences after a stroke, it is likely due to damage in the left frontal lobe. The left frontal lobe is responsible for language production and damage to this area can lead to a condition called Broca's aphasia. Patients with Broca's aphasia have trouble forming coherent and meaningful sentences.
