Problem: I have a new situation: Owen inherited two pieces of land. The Eastern land was in fact some wetlands, not very good for building or farming on it, but the Western land had a good rich soil good for agriculture. But I can use this background: When soil is flooded, hypoxia develops, as soil microorganisms consume oxygen faster than diffusion occurs. The presence of hypoxic soils is one of the defining characteristics of wetlands. Many wetland plants possess aerenchyma, and in some, such as water-lilies, there is mass flow of atmospheric air through leaves and rhizomes. There are many other chemical consequences of hypoxia. For example, nitrification is inhibited as low oxygen occurs and toxic compounds are formed, as anaerobic bacteria use nitrate, manganese, and sulfate as alternative electron acceptors. The reduction-oxidation potential of the rhizhosphere decreases and metal ions such as iron and manganese precipitate. Aerenchyma is a modification of the parenchyma. What is an answer for this question: Which land had more flooded soil?

A: Eastern

Problem: I have a new situation: Manny and Annie were two foodie friends. Manny was a health conscious person, he ate organic foods and drank organic milk only. Annie liked all foods, whether they were organic or not. But I can use this background: As for the public health or food safety concern, organic foods are intended to be healthy, free of contaminations and free from agents that could cause human diseases. Organic milk is meant to have no chemical residues to consumers, and the restrictions on the use of antibiotics and chemicals in organic food production has the purpose to accomplish this goal. Although dairy cows in both organic and conventional farming practices can be exposed to pathogens, it has been shown that, because antibiotics are not permitted as a preventative measure in organic practices, there are far fewer antibiotic resistant pathogens on organic farms. This dramatically increases the efficacy of antibiotics when/if they are necessary. What is an answer for this question: Which friend drank more milk with no chemical residues?

A: Manny

Problem: I have a new situation: Two colleagues studied at the same university. Nick studied the brains of birds, while Joe studied the brains of mammals. But I can use this background: The brains of all mammals have a unique layer of nerve cells covering the cerebrum. This layer is called the neocortex (the pink region of the brains in Figure above ). The neocortex plays an important role in many complex brain functions. In some mammals, such as rats, the neocortex is relatively smooth. In other mammals, especially humans, the neocortex has many folds. The folds increase the surface area of the neocortex. The larger this area is, the greater the mental abilities of an animal. What is an answer for this question: Which colleague studied less about the human neocortex having many folds?

A: Nick

Problem: I have a new situation: Different wavelength electromagnetic radiations have different uses. John is a physicist. He needed to find appropriate wavelength electromagnetic radiations for his experiments. To that end, he selected three electromagnetic radiations, microwaves, infrared light, and visible light. He noted microwaves as case A, infrared as case B, and visible light as case C. But I can use this background: Infrared (IR) light is electromagnetic radiation with a wavelength between 0.7 and 300 micrometers, which corresponds to a frequency range between 430 and 1 THz respectively. IR wavelengths are longer than that of visible light, but shorter than that of microwaves. Infrared may be detected at a distance from the radiating objects by "feel." Infrared sensing snakes can detect and focus infrared by use of a pinhole lens in their heads, called "pits". Bright sunlight provides an irradiance of just over 1 kilowatt per square meter at sea level. Of this energy, 53% is infrared radiation, 44% is visible light, and 3% is ultraviolet radiation. What is an answer for this question: Would case B have longer or shorter wavelengths than case C?

A:
longer
