Task: Question Answering
Input (English): Background Paragraph: Nearsightedness, or myopia, is the condition in which nearby objects are seen clearly, but distant objects appear blurry. The Figure below shows how it occurs. The eyeball is longer (from front to back) than normal. This causes images to be focused in front of the retina instead of on the retina. Myopia can be corrected with concave lenses. The lenses focus images farther back in the eye, so they fall on the retina instead of in front of it. 
Story: Two siblings went to the eye doctor, they needed eyeglasses. As it turned out, Ann had myopia, and Jane had farsightedness. They both bought eyeglasses. 
Question: Which sister had shorter eyeballs?
Output (English): Jane.
