Question: I read this background article the other day: During May, June, and July, the Northern Hemisphere is exposed to more direct sunlight because the hemisphere faces the Sun. The same is true of the Southern Hemisphere in November, December, and January. It is Earth's axial tilt that causes the Sun to be higher in the sky during the summer months, which increases the solar flux. However, due to seasonal lag, June, July, and August are the warmest months in the Northern Hemisphere while December, January, and February are the warmest months in the Southern Hemisphere. I am facing a new situation today: Tim and Allen were two pen pals, Tim lived in Canada, while Allen lived in Australia. they were chatting about the weather and the fact that their two countries are situated in two different hemispheres. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which person experiences warmer weather in December, Tim or Allen?
Answer: Allen
[Q]: I read this background article the other day: Blue ice occurs when snow falls on a glacier, is compressed, and becomes part of the glacier. Air bubbles are squeezed out and ice crystals enlarge, making the ice appear blue. Small amounts of regular ice appear to be white because of air bubbles inside them and also because small quantities of water appear to be colourless. In glaciers, the pressure causes the air bubbles to be squeezed out, increasing the density of the created ice. Large quantities of water appear to be blue, as it absorbs other colours more efficiently than blue. A large piece of compressed ice, or a glacier, similarly appears blue. I am facing a new situation today: Mike likes to visit places. This winter he is visiting Greenland. First, he visited Lake A, which is very small. Then he visited Lake B, which is huge. While visiting Lake B he went to a local pub. There he heard other tourists talking about two nearby glaciers, glacier C and glacier D. They said that glacier C had a snowfall and the snow became part of the glacier, but glacier D didn't have any snowfall. Mike is getting ready to visit those glaciers. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which glacier would have thinner ice?
****
[A]: glacier D
input: Please answer the following: 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: Ted had 2 uncles. Uncle Jerry was getting up there in age, he was 78 years-old. Uncle Tom was younger, he was in his early 50's and still very active and productive. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which uncle had retired from work?
++++++++++
output: Jerry
Please answer this: I read this background article the other day: Earthquakes may take place every day near a volcano. But before an eruption, the number and size of earthquakes increases. This is the result of magma pushing upward into the magma chamber. This motion causes stresses on neighboring rock to build up. Eventually the ground shakes. A continuous string of earthquakes may indicate that a volcano is about to erupt. Scientists use seismographs to record the length and strength of each earthquake. I am facing a new situation today: Two neighboring cities are situated in a volcanic area with lots of earthquakes. Park city is situated near a very active volcano, while Hill city is situated 50 miles north. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which city experiences fewer continuous strings of earthquakes?
++++++++
Answer: Hill
Problem: I read this background article the other day: Cholesterol can't dissolve in the blood. It has to be transported to and from the cells by carriers called lipoproteins. Low-density lipoprotein, or LDL, is known as "bad" cholesterol. High-density lipoprotein (HDL) is known as good cholesterol. When too much LDL cholesterol circulates in the blood, it can slowly build up in the inner walls of the arteries that feed the heart and brain. Together with other substances, it can form plaque, and lead to atherosclerosis. If a clot forms and blocks a narrowed artery, a heart attack or stroke can result. Cholesterol comes from the food you eat as well as being made by the body. To lower bad cholesterol, a diet low in saturated fat and dietary cholesterol should be followed. Regular aerobic exercise also lowers LDL cholesterol and increases HDL cholesterol. I am facing a new situation today: Michael and Robert are two patients at a cardiology clinic. Both just received their blood test results and were told that they need to improve their cholesterol levels. They were each recommended to begin exercising regularly. Michael took this advice to heart, and began regular aerobic exercise every week. Robert, on the other hand, only performs aerobic exercise every couple of weeks. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Who is more likely to have LDL cholesterol build up in the inner walls of their arteries?

A: Robert
input: Please answer the following: I read this background article the other day: In grassland, much of the organic matter added to the soil is from the deep, fibrous, grass root systems. By contrast, tree leaves falling on the forest floor are the principal source of soil organic matter in the forest. Another difference is the frequent occurrence in the grasslands of fires that destroy large amounts of aboveground material but stimulate even greater contributions from roots. Also, the much greater acidity under any forests inhibits the action of certain soil organisms that otherwise would mix much of the surface litter into the mineral soil. As a result, the soils under grasslands generally develop a thicker A horizon with a deeper distribution of organic matter than in comparable soils under forests, which characteristically store most of their organic matter in the forest floor (O horizon) and thin A horizon. I am facing a new situation today: Two pedologists studied different types of soil. Yun studied forest soils, while Jian studied grassland soil. They were both very surprised with they findings. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which scientist read more about tree leaves falling on the forest floor?
++++++++++
output:
Yun
