Problem: Given the question: Please answer correctly the following question related to the paragraph below. Which group of antelope will have greater reproductive success? In sub-Saharan Africa there are two predominant groups of antelope present. The first group of antelope, group A, have long necks and strong teeth. The second group of antelope, group B, have shorter necks and weaker teeth. Because of their longer necks and stronger teeth, the antelope from group A are more easily able to pick fruit and leaves from the tall trees in the region compared to antelope from group B. Hint: The theory of evolution by natural selection was proposed at about the same time by both Charles Darwin and Alfred Russel Wallace, shown in Figure below , and was set out in detail in Darwin's 1859 book On the Origin of Species . Natural selection is a process that causes heritable traits that are helpful for survival and reproduction to become more common, and harmful traits, or traits that are not helpful or advantageous for survival to become more rare in a population of organisms. This occurs because organisms with advantageous traits are more "fit" to survive in a particular environment and have "adapted" to the conditions of that environment. These individuals will have greater reproductive success than organisms less fit for survival in the environment. This will lead to an increase in the number of organisms with the advantageous trait(s) over time. Over many generations, adaptations occur through a combination of successive, small, random changes in traits, and natural selection of those variants best-suited for their environment. Natural selection is one of the cornerstones of modern biology.

group A
input question: Please answer correctly the following question related to the paragraph below. Which village was less exposed to diseases because of crowded living conditions? A team of archaeologists studied two human settlements, village Alpha from about 11000 years ago and village Beta, which existed 9000 years ago. Village Beta was bigger, because their inhabitants already knew about and practiced agriculture. Hint: Human beings invented agriculture about 10,000 years ago. This provided a bigger, more dependable food supply. It also allowed people to settle down in villages and cities for the first time. Birth rates went up because there was more food and settled life had other advantages. Death rates also rose because of crowded living conditions and diseases that spread from domestic animals. Because the higher birth rates were matched by higher death rates, the human population continued to grow very slowly.???
output answer: Alpha
Please answer correctly the following question related to the paragraph below. Which land had more wetland plants growing on it? Owen inherited two pieces of land. The Eastern land was covered in wetlands, not very good for building or farming on it, but the Western land had a good rich soil good for agriculture. Hint: When soil is flooded, hypoxia develops, as soil microorganisms consume oxygen faster than diffusion occurs. The presence of hypoxic soils is one of the defining characteristics of wetlands. Many wetland plants possess aerenchyma, and in some, such as water-lilies, there is mass flow of atmospheric air through leaves and rhizomes. There are many other chemical consequences of hypoxia. For example, nitrification is inhibited as low oxygen occurs and toxic compounds are formed, as anaerobic bacteria use nitrate, manganese, and sulfate as alternative electron acceptors. The reduction-oxidation potential of the rhizhosphere decreases and metal ions such as iron and manganese precipitate. Aerenchyma is a modification of the parenchyma.

Answer: Eastern
Q: Please answer correctly the following question related to the paragraph below. Which material would be worse suited to make a bouncy ball? An inventor named Nelly is tinkering around in her home office where she has created two new types of material that could be used in products. The first one she is calling Glubber, and the second she has named Malk. To try to figure out what type of products these new materials may be used for, Nelly is performing various tests. The first test she is doing is securing one end of the material to a table and then pulling on it and letting it go. When she performs this test on some Glubber, the material quickly snaps back toward the table. Performing the same process with some Malk, the material slowly crawls along the floor as it makes its way back to the table. Hint: Something that is elastic can return to its original shape after being stretched or compressed. This property is called elasticity . As you stretch or compress an elastic material like a bungee cord, it resists the change in shape. It exerts a counter force in the opposite direction. This force is called elastic force . The farther the material is stretched or compressed, the greater the elastic force becomes. As soon as the stretching or compressing force is released, elastic force causes the material to spring back to its original shape. You can watch a demonstration of elastic force at this URL:
A: Malk
Question: Please answer correctly the following question related to the paragraph below. Which cell is not exhibiting diffusion? Two cells, Cell B and Cell C, are being examined under microscopes by students in a science class. While looking at the cells, one student, Kim, notices that there is a noticeable trend in Cell B for a particular substance to try to group up in a more concentrated area. In Cell C though, she notices that the same substance is spreading apart and finding less concentrated areas to move to. Hint: Active transport occurs when a substance passes through the cell membrane with the help of extra energy. This happens when a substance moves from an area where it is less concentrated to an area where it is more concentrated. This is the opposite of diffusion. The substance moves up, instead of down, the concentration gradient. Like rolling a ball uphill, this requires an input of energy. The energy comes from the molecule named ATP (adenosine triphosphate). The energy allows special transport proteins called pumps to move substances to areas of higher concentration. An example is the sodium-potassium pump.
Answer: Cell B
Please answer this: Please answer correctly the following question related to the paragraph below. Which student studied more about wolves? 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.
