input question: I read this background article the other day: Groundwater salinization compromises buffering properties. Vegetation clearance, along with irrigation, causes serious issues. Irrigation increases the water table and mobilizes salts, and vegetation clearance allows it to come in contact with water habitats and vegetation. This stresses species not adapted to high salinity. High levels of salinity reduces water uptake in plants, by causing stomatal closure, reducing photosynthesis. Forests undergo decline in areas of high salinity and shallow groundwater depths because these conditions make them more susceptible to droughts. Forests undergo decline in areas of high salinity and shallow groundwater depths making them more susceptible to droughts. I am facing a new situation today: In the sixteenth century the State of Michigan had forests all over. But that has long been gone. Especially, in the state's northeast part the vegetation has been cleared in the twentieth century. Wooded areas were replaced by farm lands. All these farmlands were under heavy Irrigation. At one time, in the sixteenth century, plant species like elm and oak used to be plentiful. We still had some elms and oaks in the twentieth century, but they were not great many in number. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which century saw northeast Michigan's water table increased, sixteenth century or twentieth century????
output answer: twentieth century
I read this background article the other day: A catalyst works by providing a lower energy pathway from reactants to products. The use of a catalyst involves intermediate reactions which have lower activation complexes than the original reaction. On a simplified reaction energy diagram, this can be thought of as lowering the activation energy for a given transformation. If the activation energy of a reaction is decreased, more collisions will have enough energy to overcome this lower barrier, so the reactant-to-product transformation will occur more frequently. As a result, the overall reaction rate will be higher than for an identical reaction with a larger activation energy barrier. I am facing a new situation today: A chemist is working in the lab with two beakers, beaker R and beaker T, filled with identical solutions. In her experiment, she is going to pour one liquid into beaker R and the same amount of a different liquid into beaker T. After pouring the liquid into beaker R, there is no noticeable change. Pouring the liquid into beaker T, she observes a change in the liquid. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: The reaction in which beaker has a higher activation energy?
----
Answer: beaker R
Q: I read this background article the other day: Predators play an important role in an ecosystem. For example, if they did not exist, then a single species could become dominant over others. Grazers on a grassland keep grass from growing out of control. Predators can be keystone species . These are species that can have a large effect on the balance of organisms in an ecosystem. For example, if all of the wolves are removed from a population, then the population of deer or rabbits may increase. If there are too many deer, then they may decrease the amount of plants or grasses in the ecosystem. Decreased levels of producers may then have a detrimental effect on the whole ecosystem. In this example, the wolves would be a keystone species. I am facing a new situation today: Two teams studied two types of animals: team A studied predators, while team B studied grazers. They learned a lot from this experience. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which team learned more about wolves?
A: team A
Question: I read this background article the other day: A) In a straight-chain molecule, all the carbon atoms are lined up in a row like cars of a train. The carbon atoms form the "backbone" of the molecule. B) In a branched-chain molecule, at least one of the carbon atoms branches off from the backbone. C) In a cyclic molecule, the chain of carbon atoms is joined at the two ends to form a ring. Each ring usually contains just five or six carbon atoms, but rings can join together to form larger molecules. A cyclic molecule generally has higher boiling and melting points than straight-chain and branched-chain molecules. I am facing a new situation today: Mark works as a scientist for a molecular research institute. Today, he has three samples of molecule in front of him, sample A, sample B, and sample C. Sample A is a straight-chain molecule; sample B is a branched-chain molecule; and sample C is a cyclic molecule. Mark's job is to determine the characteristics of each sample. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which sample would have lower boiling point, sample A or sample C?
Answer: sample A
[Q]: I read this background article the other day: The dangers of global warming are being increasingly studied by a wide global consortium of scientists. These scientists are increasingly concerned about the potential long-term effects of global warming on our natural environment and on the planet. Of particular concern is how climate change and global warming caused by anthropogenic, or human-made releases of greenhouse gases, most notably carbon dioxide, can act interactively, and have adverse effects upon the planet, its natural environment and humans' existence. It is clear the planet is warming, and warming rapidly. This is due to the greenhouse effect, which is caused by greenhouse gases, which trap heat inside the Earth's atmosphere because of their more complex molecular structure which allows them to vibrate and in turn trap heat and release it back towards the Earth. This warming is also responsible for the extinction of natural habitats, which in turn leads to a reduction in wildlife population.The most recent report from the Intergovernmental Panel on Climate Change (the group of the leading climate scientists in the world) concluded that the earth will warm anywhere from 2.7 to almost 11 degrees Fahrenheit (1.5 to 6 degrees Celsius) between 1990 and 2100. I am facing a new situation today: Two earth-like planets orbited the same star. The inhabitants of Earth I released greenhouse gases into the atmosphere. Earth II, however, was much more conscious about the environment and protected it from anthropogenic changes. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which planet did not cause the greenhouse effect?
****
[A]: Earth II
Problem: Given the question: I read this background article the other day: If all the other factors influencing humidity remain constant, at ground level the relative humidity rises as the temperature falls. This is because less vapor is needed to saturate the air, so vapor condenses as the temperature falls. In normal conditions, the dew point temperature will not be greater than the air temperature because relative humidity cannot exceed 100%.[4] I am facing a new situation today: Sam lived in Chicago for many years and experienced those high humidity days during the summer, the Indian summers in October and harsh and humid winters, so he decided to move to San Diego, in a warmer and much dryer climate. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which city has less air humidity during summer?
++++++++++++++++++++++++++++++++
The answer is:
San Diego
