Question: I read this background article the other day: 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. I am facing a new situation today: two buildings had different tenants. Building Y had many seniors over 65 years of age, and building X had individuals under 65 years old. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which building had fewer people that have more time for their grandchildren?
Answer: building X
[Q]: I read this background article the other day: Generally, nearsightedness first occurs in school-age children. There is some evidence that myopia is inherited. If one or both of your parents need glasses, there is an increased chance that you will too. Individuals who spend a lot of time reading, working or playing at a computer, or doing other close visual work may also be more likely to develop nearsightedness. Because the eye continues to grow during childhood, myopia typically progresses until about age 20. However, nearsightedness may also develop in adults due to visual stress or health conditions such as diabetes. A common sign of nearsightedness is difficulty seeing distant objects like a movie screen or the TV, or the whiteboard or chalkboard in school. I am facing a new situation today: Two siblings were going to school. Mary experienced headaches, so he was sent to the eye doctor. The doctor concluded she was nearsighted and prescribed her eyeglasses. Ben had farsightedness. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which sibling had Myopia?
****
[A]: Mary
input: Please answer the following: I read this background article the other day: A mycorrhiza (Greek for "fungus roots") is a symbiotic association between a fungus and the roots of a plant. In a mycorrhizal association, the fungus may colonize the roots of a host plant by either growing directly into the root cells, or by growing around the root cells. This association provides the fungus with relatively constant and direct access to glucose, which the plant produces by photosynthesis. The mycelia of the fungi increase the surface area of the plant's root system. The larger surface area improves water and mineral nutrient absorption from the soil. I am facing a new situation today: Fox and Ken were two aspiring horticulturists. Ken studied more about plant pollination, while Fox studied about mycorrhizal fungi. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which friend read less about fungi growing around the root cells?
++++++++++
output: Ken
Please answer this: I read this background article the other day: As time passes, the number of HIV copies keeps increasing, while the number of helper T cells keeps decreasing. The graph in Figure below shows how the number of T cells typically declines over a period of many years following the initial HIV infection. As the number of T cells decreases, so does the ability of the immune system to defend the body. As a result, an HIV-infected person develops frequent infections. Medicines can slow down the virus but not get rid of it, so there is no cure at present for HIV infections or AIDS. There also is no vaccine to immunize people against HIV infection, but scientists are working to develop one. I am facing a new situation today: Mike is a physician who treats HIV-infected patients. Today, he is seeing two patients, patient A and patient B. Patient A is infected with HIV, but patient B is not infected with HIV. Mike is trying to figure out how HIV-infected patient is different from the patient who is not infected with HIV. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which patient has lower chance of developing infections, patient A or patient B?
++++++++
Answer: patient B
Problem: I read this background article the other day: Regions on the Earth's surface (or in its atmosphere) that are high above mean sea level are referred to as high altitude. High altitude is sometimes defined to begin at 2,400 meters (8,000 ft) above sea level.[5][6][7] At high altitude, atmospheric pressure is lower than that at sea level. This is due to two competing physical effects: gravity, which causes the air to be as close as possible to the ground; and the heat content of the air, which causes the molecules to bounce off each other and expand.[8] I am facing a new situation today: Ken is an avid mountain climber. This year he reached the summits of two mountains, mountain A and mountain B. Mountain A is only 5000 ft tall while mountain B is 15000 ft tall. He has also learned a fun fact that water boils faster and at lower temperature at low atmospheric pressure. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Would mountain B summit be considered high altitude or low altitude?

A: high altitude
input: Please answer the following: I read this background article the other day: While the Grants were on the Galapagos, a drought occurred. As a result, fewer seeds were available for finches to eat. Birds with smaller beaks could crack open and eat only the smaller seeds. Birds with bigger beaks could crack and eat seeds of all sizes. As a result, many of the small-beaked birds died in the drought. Birds with bigger beaks survived and reproduced (see Figure below ). Within 2 years, the average beak size in the finch population increased. Evolution by natural selection had occurred. I am facing a new situation today: Two neighboring islands inhabited by thousands of birds each were hit by extreme weather. While Port island experienced wet weather over the past 3 summers, Bank island experienced severe drought, therefore the food supply on the island diminished. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which island had fewer birds with bigger beaks reproduce?
++++++++++
output:
Port
