Problem: Please answer correctly the following question related to the paragraph below. Which country uses more radioactive elements? Iran an Iraq are 2 neighbors. Iraq produces its electricity by burning fossil fuels, while Iran uses nuclear fission as its energy source. Hint: 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.

A: Iran
Problem: Given the question: Please answer correctly the following question related to the paragraph below. Which student found out that grazers on a grassland keep grass from growing out of control? Two students from the same class, studies different types of animals. Bill studied predators, while John studied grazers. Hint: 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.

input question: Please answer correctly the following question related to the paragraph below. Which group had more mutations in the DNA of sex cells? Scientists studied mutations on groups of fruit flies. Group A presented gemline mutations, while group B presented somatic mutations. Hint: Once again, a mutation is the change in the DNA or RNA sequence. In multicellular organisms, mutations can be subdivided into germline mutations and somatic mutations. Germline mutations occur in the DNA of sex cells, or gametes, and are therefore potentially very serious. These mutations can be passed to the next generation. If the zygote contains the mutation, every cell in the resulting organism will have that mutation. If the mutation results in a disease phenotype, the mutation causes what is called a hereditary disease. Somatic mutations , which occur in somatic, or body, cells, cannot be passed to the next generation (offspring). Mutations present in a somatic cell of an organism will be present (by DNA replication and mitosis) in all descendants of that cell. If the mutation is present in a gene that is not used in that cell type, the mutation may have no effect. On the other hand, the mutation may lead to a serious medical condition such as cancer.???
output answer: Group A
Please answer correctly the following question related to the paragraph below. Which group had some people that might have required an epinephrine injection? The doctors used used the newly discovered allergy medicine on two groups of people. As a result, group Alpha experienced mild allergy symptoms, while group Beta continued experiencing severe allergy symptoms and remained hospitalized requiring additional treatment. Hint: Allergy symptoms can range from mild to severe. Mild symptoms might include itchy eyes, sneezing, and a runny nose. Severe symptoms can cause difficulty breathing, which may be life threatening. Keep in mind that it is the immune system and not the allergen that causes the allergy symptoms. Allergy symptoms can be treated with medications such as antihistamines. Severe allergic reactions may require an injection of the hormone epinephrine. These treatments lessen or counter the immune system's response.

Answer: group Beta
Q: Please answer correctly the following question related to the paragraph below. If Bill edited one sound to have a shorter wavelength did its frequency go up or down? Bill is working in a sound studio recording sound effects for a short film that he is working on. Some of the sounds he captured have a very high frequency and others are very low frequency. When he is done he begins to edit the sound with a computer program. Hint: Figure B above shows an important relationship between the wavelength and frequency of a wave. The top wave clearly has a shorter wavelength than the second wave. However, if you picture yourself at a stationary point watching these waves pass by, more waves of the first kind would pass by in a given amount of time. Thus the frequency of the first waves is greater than that of the second waves. Wavelength and frequency are therefore inversely related. As the wavelength of a wave increases, its frequency decreases. The equation that relates the two is
A: up
[Q]: Please answer correctly the following question related to the paragraph below. Who is less likely to have LDL cholesterol build up in the inner walls of their arteries? Michael and Robert are two patients at a cardiology clinic. Both just received their blood test results and were told that they need to improve their cholesterol levels. They were each recommended to begin exercising regularly. Michael took this advice to heart, and began regular aerobic exercise every week. Robert, on the other hand, only performs aerobic exercise every couple of weeks. Hint: Cholesterol can't dissolve in the blood. It has to be transported to and from the cells by carriers called lipoproteins. Low-density lipoprotein, or LDL, is known as "bad" cholesterol. High-density lipoprotein (HDL) is known as good cholesterol. When too much LDL cholesterol circulates in the blood, it can slowly build up in the inner walls of the arteries that feed the heart and brain. Together with other substances, it can form plaque, and lead to atherosclerosis. If a clot forms and blocks a narrowed artery, a heart attack or stroke can result. Cholesterol comes from the food you eat as well as being made by the body. To lower bad cholesterol, a diet low in saturated fat and dietary cholesterol should be followed. Regular aerobic exercise also lowers LDL cholesterol and increases HDL cholesterol.
