input: Please answer the following: I read this background article the other day: Because the gravitational field created by the Moon weakens with distance from the Moon, it exerts a slightly stronger than average force on the side of the Earth facing the Moon, and a slightly weaker force on the opposite side. The Moon thus tends to "stretch" the Earth slightly along the line connecting the two bodies. The solid Earth deforms a bit, but ocean water, being fluid, is free to move much more in response to the tidal force, particularly horizontally. As the Earth rotates, the magnitude and direction of the tidal force at any particular point on the Earth's surface change constantly; although the ocean never reaches equilibriumthere is never time for the fluid to "catch up" to the state it would eventually reach if the tidal force were constantthe changing tidal force nonetheless causes rhythmic changes in sea surface height. I am facing a new situation today: Mike was reading about an instrument that could measure gravity, gravimeter. He then found how gravimeter was used to measure the gravitational field of the Moon. He read about two distinct cases where the Moon's gravitational field was measured on earth, side A and side B. In side A the Moon's gravity was measured from the side where the Earth was facing the Moon. And in side B the Moon's gravitational field was measured from the opposite side of the Earth. He found these two locations showed very different consequences of Moon's gravitational field. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which side would see less deformed Earth, side A or side B?
++++++++++
output: side B

input: Please answer the following: I read this background article the other day: Soil formation, or pedogenesis, is the combined effect of physical, chemical, biological and anthropogenic processes working on soil parent material. Soil is said to be formed when organic matter has accumulated and colloids are washed downward, leaving deposits of clay, humus, iron oxide, carbonate, and gypsum, producing a distinct layer called the B horizon. This is a somewhat arbitrary definition as mixtures of sand, silt, clay and humus will support biological and agricultural activity before that time. These constituents are moved from one level to another by water and animal activity. As a result, layers (horizons) form in the soil profile. The alteration and movement of materials within a soil causes the formation of distinctive soil horizons. However, more recent definitions of soil embrace soils without any organic matter, such as those regoliths that formed on Mars and analogous conditions in planet Earth deserts.An example of the development of a soil would begin with the weathering of lava flow bedrock, which would produce the purely mineral-based parent material from which the soil texture forms. Soil development would proceed most rapidly from bare rock of recent flows in a warm climate, under heavy and frequent rainfall. Under such conditions, plants (in a first stage nitrogen-fixing lichens and cyanobacteria then epilithic higher plants) become established very quickly on basaltic lava, even though there is very little organic material. The plants are supported by the porous rock as it is filled with nutrient-bearing water that carries minerals dissolved from the rocks. Crevasses and pockets, local topography of the rocks, would hold fine materials and harbour plant roots. The developing plant roots are associated with mineral-weathering mycorrhizal fungi that assist in breaking up the porous lava, and by these means organic matter and a finer mineral soil accumulate with time. Such initial stages of soil development have been described on volcanoes, inselbergs, and glacial moraines. I am facing a new situation today: Ben and Jerry studied agricultural sciences. Ben was specialized in pedology and pedogenesis, while Jerry specialized in entomology and phytopathology. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which person learned more about the accumulation of organic matter?
++++++++++
output: Ben

input: Please answer the following: I read this background article the other day: Reduction of the area of Arctic sea ice reduces the planet's average albedo, possibly resulting in global warming in a positive feedback mechanism. Research shows that the Arctic may become ice free in the summer for the first time in human history within by 2040. Estimates vary for when the last time the Arctic was ice free: 65 million years ago when fossils indicate that plants existed there to as few as 5,500 years ago; ice and ocean cores going back 8000 years to the last warm period or 125,000 during the last intraglacial period.Warming temperatures in the Arctic may cause large amounts of fresh meltwater to enter the north Atlantic, possibly disrupting global ocean current patterns. Potentially severe changes in the Earth's climate might then ensue.As the extent of sea ice diminishes and sea level rises, the effect of storms such as the Great Arctic Cyclone of 2012 on open water increases, as does possible salt-water damage to vegetation on shore at locations such as the Mackenzie's river delta as stronger storm surges become more likely.Global warming has increased encounters between polar bears and humans. Reduced sea ice due to melting is causing polar bears to search for new sources of food. Beginning in December 2018 and coming to an apex in February 2019, a mass invasion of polar bears into the archipelago of Novaya Zemlya caused local authorities to declare a state of emergency. Dozens of polar bears were seen entering homes and public buildings and inhabited areas. I am facing a new situation today: Mike was reading about climate change. The author compared two different time periods, era A and era B. Era A was set in the present day. But era B was set in the year 2040. Mike was surprised to find how Arctic area would change in the coming years. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which period would see less human polar bear encounters, era A or era B?
++++++++++
output: era A

input: Please answer the following: I read this background article the other day: HIV , or human immunodeficiency virus, causes AIDS. AIDS stands for "acquired immune deficiency syndrome." It is a condition that causes death and does not have a known cure. AIDS usually develops 10 to 15 years after a person is first infected with HIV. The development of AIDS can be delayed with proper medicines. The delay can be well over 20 years with the right medicines. Today, individuals who acquire HIV after 50 years of age can expect to reach an average human life span. I am facing a new situation today: The police arrested two homeless people. James was 35 and had been HIV positive for 20 years, and Bill, who was 54 and was not HIV positive. They booked them and let them go. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which person had more chances of getting AIDS?

James
