input: Please answer the following: I read this background article the other day: Clouds on Earth are made of water vapor. Venus's clouds are a lot less pleasant. They are made of carbon dioxide, sulfur dioxide and large amounts of corrosive sulfuric acid! The atmosphere of Venus is so thick that the pressure on the surface of Venus is very high. In fact, it is 90 times greater than the pressure at Earth's surface! The thick atmosphere causes a strong greenhouse effect. As a result, Venus is the hottest planet. Even though it is farther from the Sun, Venus is much hotter even than Mercury. Temperatures at the surface reach 465C (860F). That's hot enough to melt lead! I am facing a new situation today: Brad and Joe studied atmospheric conditions on different planets of our solar system. Joe studied about Earth, while Brad studied more about Venus. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which person learned about the planet with a thicker atmosphere?
++++++++++
output: Brad
Please answer this: I read this background article the other day: There is a zone of the atmosphere in which ozone absorbs some 98% of non-ionizing but dangerous UV-C and UV-B. This so-called ozone layer starts at about 20 miles (32 km) and extends upward. Some of the ultraviolet spectrum that does reach the ground (the part that begins above energies of 3.1 eV, a wavelength less than 400 nm) is non-ionizing, but is still biologically hazardous due to the ability of single photons of this energy to cause electronic excitation in biological molecules, and thus damage them by means of unwanted reactions. An example is the formation of pyrimidine dimers in DNA, which begins at wavelengths below 365 nm (3.4 eV), which is well below ionization energy. This property gives the ultraviolet spectrum some of the dangers of ionizing radiation in biological systems without actual ionization occurring. In contrast, visible light and longer-wavelength electromagnetic radiation, such as infrared, microwaves, and radio waves, consists of photons with too little energy to cause damaging molecular excitation, and thus this radiation is far less hazardous per unit of energy. I am facing a new situation today: John was interested in the Sun's radiations that Earth receives. One of the radiations was in the ultraviolet spectrum. He categorized it as spec A. The other radiation was the visible light. He categorized it as spec B. He then searched online to find the pros and cons of each of them. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: In spec B, would the photons have less or more energy than in spec A?

Answer: less
Problem: I read this background article the other day: Alkali, or Alkaline, soils are clay soils with high pH (> 8.5), a poor soil structure and a low infiltration capacity. Often they have a hard calcareous layer at 0.5 to 1 metre depth. Alkali soils owe their unfavorable physico-chemical properties mainly to the dominating presence of sodium carbonate, which causes the soil to swell[1] and difficult to clarify/settle. They derive their name from the alkali metal group of elements, to which sodium belongs, and which can induce basicity. Sometimes these soils are also referred to as alkaline sodic soils. Alkaline soils are basic, but not all basic soils are alkaline. I am facing a new situation today: Pat has 2 acres of land next to Tim's property. Tim's land is of similar size. The clay soil on Tim's property is very alkaline, so he had to amend it with aluminum salts to make it more acidic in order to grow crops. The soil on Pat's parcel has a good structure and high infiltration capacity. Pat gets twice as much food of his land every year. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which soil is more alkaline, the one on Pat's or the one on Tim's?

A: Tim's
Problem: Given the question: I read this background article the other day: As shown here, pressure decreases to less than 25% of ground-level atmospheric pressure when we get to an altitude of about six miles. Since this is a common cruising altitude for commercial airplanes, pressurized cabins are needed for the comfort and survival of the passengers. This is because the density of the air decreases along with the decreasing air pressure, so there is less oxygen in a breath of air. You've probably noticed this effect in high-mountain areas, as it often feels harder to breath. I am facing a new situation today: Pam and Angela live in different cities and are talking to each other on the phone while they are sitting outside. Pam lives in Dunder, a city located at sea level, and Angela lives in Mifflin, a city up high in the mountains. Although they don't get to see each other much any more due to the distance between them, they make sure to stay in regular contact. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which woman gets less oxygen per single breath?
++++++++++++++++++++++++++++++++
The answer is:
Angela
input question: I read this background article the other day: Animals and some bacteria and fungi carry out lactic acid fermentation. Lactic acid is a waste product of this process. Our muscles perform lactic acid fermentation during strenuous exercise, since oxygen cannot be delivered to the muscles quickly enough. The buildup of lactic acid is believed to make your muscles sore after exercise. Bacteria that produce lactic acid are used to make cheese and yogurt. The lactic acid causes the proteins in milk to thicken. Lactic acid also causes tooth decay, because bacteria use the sugars in your mouth for energy. I am facing a new situation today: A group of students in biology class studied fermentation. Team A studied alcoholic fermentation, while team B learned more about lactic fermentation. They later organised a trivia contest between teams. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which team studied less about cheese and yogurt????
output answer: Team A
input question: I read this background article the other day: Another obvious change that occurs during puberty is rapid growth. This is called the adolescent growth spurt . In boys, it is controlled by testosterone. The rate of growth usually starts to increase relatively early in puberty. At its peak rate, growth in height is about 10 centimeters (almost 4 inches) per year in the average male. Growth generally remains rapid for several years. Growth and development of muscles occur toward the end of the growth spurt in height. Muscles may continue to develop and gain strength after growth in height is finished. I am facing a new situation today: Two researches studied adolescents during puberty. Tim studied males, while Dan studied females. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which researcher observed that growth generally remains rapid for several years????
output answer:
Tim
