Task: Question Answering
Input (English): Background Paragraph: Farsightedness, or hyperopia, is the condition in which distant objects are seen clearly, but nearby objects appear blurry. It occurs when the eyeball is shorter than normal (see Figure below ). This causes images to be focused in a spot that would fall behind the retina (if light could pass through the retina). Hyperopia can be corrected with convex lenses. The lenses focus images farther forward in the eye, so they fall on the retina instead of behind it. 
Story: Two people went to the eye doctor's office for an annual exam; James had farsightedness, while Bob had myopia. 
Question: Which person didn't have to wear convex lenses?
Output (English): Bob.
