input: Please answer the following: Given the background: 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. and the situation: Two neighboring towns had different demographics. Hill town had younger inhabitants, most of them in their 30's and 40's. Lake town was inhabited by elderly people, most of them above 65 years of age. Answer the following question: Which town had fewer people that have retired from work?
++++++++++
output: Hill

input: Please answer the following: Given the background: The Fink effect, also known as "diffusion anoxia",[1] "diffusion hypoxia",[2] or the "third gas effect",[3] is a factor that influences the pO2 (partial pressure of oxygen) within the alveolus. When water-insoluble gases such as anesthetic agent N2O (nitrous oxide) are breathed in large quantities they can be dissolved in body fluids rapidly. This leads to a temporary increase in both the concentrations and partial pressures of oxygen and carbon dioxide in the alveolus. and the situation: An accident occurred in a local chemical factory. Consequently, large amount of various gases been released to the atmosphere. Local hospital is evaluating all the patients who have been affected by this accident. John, a doctor at the hospital, is seeing two patients, patient A and patient B. He concluded that patient A was having Fink effect. But he didn't see any sign of Fink effect in patient B. Answer the following question: Would patient B have increased or normal partial pressure of oxygen in the alveolus?
++++++++++
output: normal

input: Please answer the following: Given the background: A period of very low rainfall occurred while the Grants were on the islands. The drought resulted in fewer seeds for the finches to eat. Birds with smaller beaks could eat only the smaller seeds. Birds with bigger beaks were better off. They could eat seeds of all sizes. Therefore, there was more food available to them. Many of the small-beaked birds died in the drought. More of the big-beaked birds survived and reproduced. Within just a couple of years, the average beak size in the finches increased. This was clearly evolution by natural selection. and the situation: Two bird islands experienced different levels of rainfall. West island experienced a lengthy drought that lasted several years. Many birds were affected by this drought. East island had several normal years as far as rainfall was concerned. Answer the following question: Which island had fewer seeds for the finches to eat?
++++++++++
output: West

input: Please answer the following: Given the background: A few insects, such as mayflies and some moths, never eat. That's because their lives are over in just a few hours or days. Once these insects become adults, they lay eggs, and then die. On the other hand, some insects are very healthy eaters. A silkworm eats enough leaves to increase its weight more than 4,000 times in just 56 days, as the silkworm increases in size about 10,000 times since birth. A locust eats its own weight in plants every day. Just imagine eating your own weight in food every day. You probably couldn't. You would most likely get very sick even if you tried. and the situation: John and Mary were studying insects. John liked to study insects that never eat, while Mary decided to study insects that are very healthy eaters. Answer the following question: Which person studied less about silkworms?
++++++++++
output:
John
