user: Problem: Given the question: The ozone layer is contained within the stratosphere. In this layer ozone concentrations are about 2 to 8 parts per million, which is much higher than in the lower atmosphere but still very small compared to the main components of the atmosphere. It is mainly located in the lower portion of the stratosphere from about 15–35 km (9.3–21.7 mi; 49,000–115,000 ft), though the thickness varies seasonally and geographically. About 90% of the ozone in Earth's atmosphere is contained in the stratosphere.  The ozone layer helps organisms by protecting them from Sun's ultraviolet radiation. To find the usefulness of ozone layer Mike wanted to see how much ozone are there in the atmosphere. He then collected three samples of atmosphere, sample A sample B, and sample C. Sample A was collected from the upper portion of the stratosphere. Sample B was collected from the lower portion of the stratosphere. Sample C was collected from the lower atmosphere.  Which sample would have lower concentration of ozone, sample A or sample B?
++++++++++++++++++++++++++++++++
The answer is:
sample A


input question: Research has shown an inverse link between income inequality and social cohesion. In more equal societies, people are much more likely to trust each other, measures of social capital (the benefits of goodwill, fellowship, mutual sympathy and social connectedness among groups who make up a social units) suggest greater community involvement, and homicide rates are consistently lower.  Ron, a sociologist, traveled to two very different societies, society A and society B, for several months each and wrote down his observations. Ron is now examining the data he gathered from the two societies in an attempt to draw scientific conclusions, and write up a paper. In society A, he found that there were high levels of income inequality, while society B had low levels of income inequality.  Which society will have lower rates of homicide????
output answer: society B


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.  Two teams studied two types of animals: team A studied predators, while team B studied grazers. They learned a lot from this experience.  Which team learned more about deer?
----
Answer: team B


Q: No doubt you already have a good idea of what temperature is. You might say that it’s how warm or cool something feels. In physics, temperature is defined as the average kinetic energy of the particles of matter. When particles of matter move more quickly, they have more kinetic energy, so their temperature is higher. With a higher temperature, matter feels warmer. When particles move more slowly, they have less kinetic energy on average, so their temperature is lower. With a lower temperature, matter feels cooler.  Matt is reheating some leftover pizza in the microwave for his stepchildren, Lauren and Emily. Lauren likes her pizza at a high temperature when reheated so Matt cooks it for a long time. Emily likes her pizza at a lower temperature so Matt only puts hers in the microwave for a couple seconds.  Does Lauren's pizza have more or less kinetic energy than Emily's?
A: more


Question: Enzymes are proteins that increase the rate of chemical reactions by reducing the amount of activation energy needed for reactants to start reacting. Enzymes are synthesized in the cells that need them, based on instructions encoded in the cell’s DNA. Enzymes aren’t changed or used up in the reactions they catalyze, so they can be used to speed up the same reaction over and over again. Enzymes are highly specific for certain chemical reactions, so they are very effective. A reaction that would take years to occur without its enzyme might occur in a split second with the enzyme. Enzymes are also very efficient, so waste products rarely form.  Students in a high school chemistry class are conducting an experiment where they perform an acid-base reaction with various conditions. Half the students, called the non-enzyme half, perform the reaction by simply mixing the chemicals together and waiting. The other half of the students, called the enzyme-half, mix the chemicals together, then add an enzyme specialized for this specific reaction.  Which group will have to wait less for the reactions to finish?
Answer: the enzyme-half


Please answer this: Old age begins in the mid-60s and lasts until the end of life. Most people over 65 have retired from work, freeing up their time for hobbies, grandchildren, and other interests. Stamina, strength, reflex time, and the senses all decline during old age, and the number of brain cells decreases as well. The immune system becomes less efficient, increasing the risk of serious illnesses such as cancer and pneumonia. Diseases such as Alzheimer’s disease that cause loss of mental function also become more common.  Doctors studied two groups of individuals: group O with people over 65, and group S with people under 65 years old. They published the results in a magazine.  Which group had more people that have free time for grandchildren?
++++++++
Answer:

assistant: group O
