[Q]: I have a new situation: 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. But I can use this background: 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. What is an answer for this question: Which soil from these two parcels has a low infiltration capacity?

[A]: Tim's

[Q]: I have a new situation: Barb and Dee studied chemistry for a school project. After little debate they decided that Dee will study volatile gases, and Barb will study greenhouse gasses. But I can use this background: Greenhouse Effect: The solar energy reaching the surface of the Earth is concentrated in short wavelengths, which can easily penetrate the greenhouse gases, such as carbon dioxide and methane. The Earth, however, is cooler than the sun and it radiates its heat in the form of energy in the far infrared range. These longer wavelengths are partially absorbed by the greenhouse gases and some of the solar heat is returned to Earth. At a certain temperature these processes are in equilibrium and the surface temperature of the Earth is stable. However, if more greenhouse gases are put in the atmosphere the amount of trapped terrestrial radiation increases, leading to an increase in global temperature. What is an answer for this question: Which girl studied more about methane?

[A]: Barb

[Q]: I have a new situation: Two neighboring counties, Brown and Green county, had different weather patterns occur last month. The weather in Brown county was quite stable, but green county experienced atmospheric convection and other related phenomena. But I can use this background: Atmospheric convection is the result of a parcel-environment instability, or temperature difference layer in the atmosphere. Different lapse rates within dry and moist air masses lead to instability. Mixing of air during the day which expands the height of the planetary boundary layer leads to increased winds, cumulus cloud development, and decreased surface dew points. Moist convection leads to thunderstorm development, which is often responsible for severe weather throughout the world. Special threats from thunderstorms include hail, downbursts, and tornadoes. What is an answer for this question: Which county had more cumulus clouds forming?

[A]: Green

[Q]: I have a new situation: Two families had children that played together in the park. Jones family were anti-vaxxers, so they never vaccinated against any disease. Dean family did all the required vaccinations. But I can use this background: You don't have to suffer through an infection to gain immunity to some diseases. Immunity can also come about by vaccination. Vaccination is the process of exposing a person to pathogens on purpose so the person will develop immunity to them. In vaccination, the pathogens are usually injected under the skin. Only part of the pathogens are injected, or else weakened or dead pathogens are used. This causes an immune response without causing the disease. Diseases you are likely to have been vaccinated against include measles, mumps, and chicken pox. What is an answer for this question: Which family had pathogens injected under the skin?
