input question: I read this background article the other day: Freezing is a common method of food preservation that slows both food decay and the growth of micro-organisms. Besides the effect of lower temperatures on reaction rates, freezing makes water less available for bacterial growth. I am facing a new situation today: Robert, a baker, has just baked a large batch of cupcakes for his store. He won't be able to sell all of his cupcakes within the next week, so he has decided to store a portion of them in the freezer to preserve them for later. He is trying to decide if he should store the cupcakes at 0 F or at 10 F in the freezer. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: If Robert initially stored the cupcakes at 0 F, but found out that increased bacterial activity could actually make the cupcakes taste better, should he raise or lower the temperature to improve the taste of the cupcakes????
output answer: raise
I read this background article the other day: Protozoa generally feed by engulfing and digesting other organisms. As consumers, they have various roles in food chains and webs. Some are predators. They prey upon other single-celled organisms, such as bacteria. In fact, protozoa predators keep many bacterial populations in check. Other protozoa are herbivores. They graze on algae. Still others are decomposers. They consume dead organic matter. There are also parasitic protozoa that live in or on living hosts. For example, the protozoan that causes malaria lives inside a human host. For their part, protozoa are important food sources for many larger organisms, including insects and worms. I am facing a new situation today: Two groups of students learned about protozoa for a school project. Group P studied more about predatory protozoa, while group G studied about grazing and parasitic protozoa, plus portozoa as food sources. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which group learned more about protozoa being food sources for insects?
----
Answer: group G
Q: I read this background article the other day: When the temperature of reactants is higher, the rate of the reaction is faster. At higher temperatures, particles of reactants have more energy, so they move faster. As a result, they are more likely to bump into one another and to collide with greater force. For example, food spoils because of chemical reactions, and these reactions occur faster at higher temperatures (see the bread on the left in the Figure below ). This is why we store foods in the refrigerator or freezer (like the bread on the right in the Figure below ). The lower temperature slows the rate of spoilage. I am facing a new situation today: Justin and Thomas are two college students conducting an experiment in their chemistry laboratory course. They are mixing together acids and bases to produce sodium based compounds. Justin conducts his reactions at a high temperature, while Thomas conducts his reactions at a lower temperature. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: In which person's reactions will the acid and base particles be less likely to collide with each other?
A: Thomas
Question: I read this background article the other day: Carbon dioxide is the most significant long-lived greenhouse gas in Earth's atmosphere. Since the Industrial Revolution anthropogenic emissions primarily from use of fossil fuels and deforestation have rapidly increased its concentration in the atmosphere, leading to global warming. Carbon dioxide also causes ocean acidification because it dissolves in water to form carbonic acid. I am facing a new situation today: Two counties were part of the same region. Green county used alternative methods to produce energy, while Brown county used fossil fuels and released a lot of carbon dioxide into the atmosphere. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which county caused more ocean acidification?
Answer: Brown
[Q]: I read this background article the other day: In the U.S., the majority of electricity is produced by burning coal or other fossil fuels. This causes air pollution, acid rain, and global warming. Fossil fuels are also limited and may eventually run out. Like fossil fuels, radioactive elements are limited. In fact, they are relatively rare, so they could run out sooner rather than later. On the other hand, nuclear fission does not release air pollution or cause the other environmental problems associated with burning fossil fuels. This is the major advantage of using nuclear fission as a source of energy. I am facing a new situation today: Two countries used different methods to produce their energy. Albania used fossil fuels, while Croatia used Nuclear fission. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which country caused less global warming?
****
[A]: Croatia
Problem: Given the question: I read this background article the other day: The benefits provided by no-tillage to predators may lead to larger predator populations, which is a good way to control pests (biological control), but also can facilitate predation of the crop itself. In corn crops, for instance, predation by caterpillars can be higher in no-till than in conventional tillage fields.In places with rigorous winter, untilled soil can take longer to warm and dry in spring, which may delay planting to less ideal dates. Another factor to be considered is that organic residue from the prior year's crops lying on the surface of untilled fields can provide a favorable environment to pathogens, helping to increase the risk of transmitting diseases to the future crop. And because no-till farming provides good environment for pathogens, insects and weeds, it can lead farmers to a more intensive use of chemicals for pest control. Other disadvantages of no-till include underground rot, low soil temperatures and high moisture.Based on the balance of these factors, and because each farm has different problems, agroecologists will not attest that only no-till or complete tillage is the right way of farming. Yet, these are not the only possible choices regarding soil preparation, since there are intermediate practices such as strip-till, mulch-till and ridge-till, all of them just as no-till categorized as conservation tillage. Agroecologists, then, will evaluate the need of different practices for the contexts in which each farm is inserted. I am facing a new situation today: Jake and Todd used different farming methods to produce their crops. Jake always tills his land, while Todd uses he no-tillage method. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which farmer provided a good environment for weeds?

The answer is:
Todd
