Task: Question Generation
Input (English): Background Paragraph: Old age begins in the mid-60s and lasts until the end of life. Most people over 65 have retired from work, freeing up their time for hobbies, grandchildren, and other interests. Stamina, strength, reflex time, and the senses all decline during old age, and the number of brain cells decreases as well. The immune system becomes less efficient, increasing the risk of serious illnesses such as cancer and pneumonia. Diseases such as Alzheimer’s disease that cause loss of mental function also become more common. 
Story: Doctor Brown examined two groups of patients: Group O, with members over 65, and group P, with members under 65 years of age. The study was about the effects on aging on the human body.
Output (English): Which group has fewer people retired from work?
