neurology/brain anatomy question...?

1. Patient suffers head injury in car accidnt, now has large blind areas in visual field, cannot see "shapes" of objects, etc.

2. Stroke victime diagnosed w/ agnosia (semantic agnosia) ; has to handle object in order to remember their name.

Select area of brain damaged in each:

occipital lobe

right temporal lobe

Broca's area

limbic system

cerebellum

reticular formation

I know it's probably not the last three, but these are the choices. I'm confused because it seems both could be due to damage in occipital lobe, but can only use each one once. Since language is basically in the left temporal lobe, right temporal lobe didn't seem correct, either. Help!
