input question: Given the background: Unfortunately, the layer of good ozone is being destroyed by air pollution. The chief culprits are chlorine and bromine gases. They are released in aerosol sprays, coolants, and other products. Loss of ozone has created an ozone hole over Antarctica. Ozone depletion results in higher levels of UV radiation reaching Earth. In humans, this increases skin cancers and eye cataracts. It also disturbs the nitrogen cycle, kills plankton, and disrupts ocean food webs. The total loss of the ozone layer would be devastating to most life. It's rate of loss has slowed with restrictions on pollutants, but it is still at risk. and the situation: The researches studied the atmosphere in Antarctica, and close to Greenland. They found out there's an ozone hole over Antarctica. Answer the following question: Which landmass had its atmosphere destroyed by bromine gasses????
output answer: Antarctica

Given the background: Candied fruit, also known as crystallized fruit or glace fruit, has existed since the 14th century. Whole fruit, smaller pieces of fruit, or pieces of peel, are placed in heated sugar syrup, which absorbs the moisture from within the fruit and eventually preserves it. Depending on size and type of fruit, this process of preservation can take from several days to several months.[1] This process allows the fruit to retain its quality for a year.[2] The continual process of drenching the fruit in syrup causes the fruit to become saturated with sugar, preventing the growth of spoilage microorganisms due to the unfavourable osmotic pressure this creates.[3] and the situation: Dan decided to preserve some fruit and roots to see how long they last before they spoil. He also bought other fruit that he plans to eat fresh. He candied plums, pears, ginger and quince, and he ate fresh apples, oranges and mango. Answer the following question: Which fruit have a lower sugar content candied plums or fresh oranges?
----
Answer: fresh oranges

Q: Given the background: 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. and the situation: Large birds are natural predators of rodents. Unfortunately, rodents consume crops in farmlands. In recent years, use of chemicals in agriculture has seen reduced number of large birds in Germany. But in some places in France farmers are cautions about using chemicals in agriculture. As a result, large bird population had been stable in France. Answer the following question: Would Germany see less or more rodents in agricultural lands than France?
A: more

Question: Given the background: New species develop naturally through the process of natural selection . Due to natural selection, organisms with traits that better enable them to adapt to their environment will tend to survive and reproduce in greater numbers. Natural selection causes beneficial heritable traits to become more common in a population and unfavorable heritable traits to become less common. For example, a giraffe's neck is beneficial because it allows the giraffe to reach leaves high in trees. Natural selection caused this beneficial trait to become more common than short necks. and the situation: Pam and Jill studied mammals. Jill was fascinated with their nutrition, while Pam was more interested and read about the natural selection phenomenon. Answer the following question: Which person studied more about beneficial heritable traits becoming more common in a population?
Answer: Pam

[Q]: Given the background: Hepatitis B is a disease of the liver. It is caused by a virus called hepatitis B, which can be passed through sexual activity. Hepatitis B causes vomiting. It also causes yellowing of the skin and eyes. The disease goes away on its own in some people. Other people are sick for the rest of their lives. In these people, the virus usually damages the liver. It may also lead to liver cancer. Medicines can help prevent liver damage in these people. There is also a vaccine to protect against hepatitis B. and the situation: Mike and John are brothers. Their dad sent them to the doctor's office to get tested for hepatitis because Mike was feeling sick all the time. It turned out Mike has hepatitis B, while John doesn't. Answer the following question: Which brother has a disease which causes yellowing of the eyes?
****
[A]: Mike

Problem: Given the question: Given the background: Beginning in the late 1970's, ozone depletion was recognized as a significant environmental issue. The most dramatic decrease in ozone occurs seasonally over the continent of Antarctica. The size and duration of the ozone hole steadily increased, with the largest hole recorded in 2006. Fortunately, most countries have recognized the danger of CFCs and dramatically curtailed their use in recent years. It is hoped that ozone depletion will slow and that the ozone layer may eventually be restored to its earlier levels. and the situation: Ben and Harry were studying about the climatic history of Earth. Ben was more attracted to learning about early Ice Ages, while Harry was curious about the Earth atmosphere and read about ozone depletion and its consequences. Answer the following question: Which person learned more about the duration of the ozone hole over Antarctica?
++++++++++++++++++++++++++++++++
The answer is:
Harry
