Step-by-step explanation:
If Abdel had a brain tumor removed and now has no vision in their left eye, it's likely that the tumor was located in Abdel's occipital lobe. The occipital lobe is primarily responsible for processing visual information, and damage to this area can result in vision problems or even blindness in the visual field of the affected hemisphere. In this case, the left occipital lobe is associated with the vision in the left eye.
