Final answer:
Mrs. Lennox, who suffered a stroke damaging a portion of her parietal lobe, is most likely to experience difficulty in spatial thinking.
Step-by-step explanation:
Mrs. Lennox, who suffered a stroke damaging a portion of her parietal lobe, is most likely to experience difficulty in spatial thinking. The parietal lobe plays a crucial role in processing sensory information and interpreting spatial relationships, so damage to this area can result in difficulties in understanding and perceiving spatial concepts such as orientation, depth perception, and spatial reasoning.
