Task: Question Answering
Input (English): Background Paragraph: Old age begins in the mid-60s and lasts until the end of life. Many 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: Dr. Smith studied a group of people under 65 called group I, and a group of people over 65 called group II. Old age signs were more obvious after the age of 65. 
Question: Which had fewer people freeing up their time for hobbies?
Output (English): group I.
