input question: I read this background article the other day: Many different chemical substances cause cancer. Dozens of chemicals in tobacco smoke, including nicotine, have been shown to cause cancer ( Figure below ). In fact, tobacco smoke is one of the main sources of chemical carcinogens. Smoking tobacco increases the risk of cancer of the lung, mouth, throat, and bladder. Using smokeless tobacco can also cause cancer. Other chemicals that cause cancer include asbestos, formaldehyde, benzene, cadmium, and nickel. I am facing a new situation today: Two ladies sit in a coffee shop. Patty smokes three packs of cigarettes a day, but her good friend Julie, doesn't smoke. They are both 65 years old. They are enjoying a coffee. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which lady is less exposed chemical carcinogens????
output answer: Julie
I read this background article the other day: Ocean acidification occurs when excess carbon dioxide in the atmosphere causes the oceans to become acidic. Burning fossil fuels has led to an increase in carbon dioxide in the atmosphere. This carbon dioxide is then absorbed by the oceans, which lowers the pH of the water. Ocean acidification can kill corals and shellfish. It may also cause marine organisms to reproduce less, which could harm other organisms in the food chain. As a result, there also may be fewer marine organisms for humans to consume. I am facing a new situation today: The biologists found out that the Indian Ocean had a lower water pH than it did a decade ago, and it became acidic. The water in the Arctic ocean still had a neutral to basic pH. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which ocean experienced more water acidification over the last decade?
----
Answer: Indian
Q: 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: John liked studying about the planets in our solar system. He recently studied and made comparisons between Earth's and Venus's atmosphere. He was amazed with what he found out. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which planet has no clouds made of sulfur dioxide?
A: Earth
Question: I read this background article the other day: Temperature is a measure of the average kinetic energy of the particles in matter. In everyday usage, temperature indicates a measure of how hot or cold an object is. Temperature is an important parameter in chemistry. When a substance changes from solid to liquid, it is because there was an increase in the temperature of the material. Chemical reactions usually proceed faster if the temperature is increased. Many unstable materials (such as enzymes) will be viable longer at lower temperatures. I am facing a new situation today: John is a scientist. Yesterday, he conducted several tests, test A, test B, test C, test D, test E, and test F. In test A he kept a substance in solid state. Then in test B he changed the same substance to liquid state. In test C he conducted a chemical reaction in room temperature. Then in test D he conducted the same chemical reaction in higher temperature. In test E he kept some enzymes in high temperature. Finally, in test F he kept the same enzymes in lower temperature. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which test would see higher temperature, test A or test B?
Answer: test B
[Q]: I read this background article the other day: Plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". This occurs in a type of glacier called a "valley glacier". As a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock. The freezing and thawing action of the ice enlarges, widens, or causes further cracks in the bedrock as it changes volume across the ice/water phase transition (a form of hydraulic wedging), gradually loosening the rock between the joints. This produces large pieces of rock called joint blocks. Eventually these joint blocks come loose and become trapped in the glacier. I am facing a new situation today: Rob likes to visit high mountainous locations. Last year he visited the the Alps mountains in Austria. There he saw an unique type of glacier called valley glacier. This year he went further east to visit the Ural mountains in Russia. There he didn't see any valley glacier. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Where there would not be joint blocks, Alps or Ural?
****
[A]: Ural
Problem: Given the question: 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 farmer will get fewer crops this year?

The answer is:
Tim
