There is a creature called a Brotor that has inhabited the planet Glarknon for thousands of years. The Brotor have two distinct traits on them, but each Brotor only has one of these traits. The vast majority of Brotors have fins on their body, but there is a very small segment of the Broto population that has arms instead of fins. Given the paragraph above, please answer correctly the following question: Which trait is more suited for the Brotor's environment? Hint: 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.

Answer: fins
Q: Archimedes was a great scientist. He was also a great inventor of machines. He once said that if he could stand somewhere, he could move the earth with his machine. Hearing that, king of Sicily called Archimedes and his fellow scientist Ptolemy to come up with great inventions. Archimedes, as everyone expected, came up with a great machine. But Ptolemy couldn't do much in such a limited time. So, his device was not a machine. Given the paragraph above, please answer correctly the following question: Whose device would have created more applied force, Archimedes or Ptolemy? Hint: Machines make work easier by increasing the amount of force that is applied, increasing the distance over which the force is applied, or changing the direction in which the force is applied. Contrary to popular belief, machines do not increase the amount of work that is done. They just change how the work is done. So if a machine increases the force applied, it must apply the force over a shorter distance. Similarly, if a machine increases the distance over which the force is applied, it must apply less force.

Question: This year scientist found concrete evidence of existence of black holes by taking photograph of one. Unfortunately, the originator of black hole theory, Stephen Hawking, was never awarded a Nobel prize despite letting science advance in big leap because his theory could not be verified during his lifetime. On the other hand, scientist B has received Nobel prize because he has based his theory on the earlier theory of scientist A. Given the paragraph above, please answer correctly the following question: Which scientist increased our understanding of the world more, scientist A or scientist B? Hint: The above example shows how science generally advances. New evidence is usually used to improve earlier ideas rather than entirely replace them. In this way, scientists gradually refine their ideas and increase our understanding of the world. On the other hand, sometimes science advances in big leaps. This has happened when a scientist came up with a completely new way of looking at things. For example, Albert Einstein came up with a new view of gravity. He said it was really just a dent in the fabric of space and time.
Answer: scientist B
[Q]: China used alternative fuels to generate electricity, while Mongolia burned lots of fossil fuels. There were frequent debates between the two countries on this matter. Given the paragraph above, please answer correctly the following question: Which country caused less global warming? Hint: Carbon dioxide is the most significant long-lived greenhouse gas in Earth's atmosphere. Since the Industrial Revolution anthropogenic emissions primarily from use of fossil fuels and deforestation have rapidly increased its concentration in the atmosphere, leading to global warming. Carbon dioxide also causes ocean acidification because it dissolves in water to form carbonic acid.

input: Please answer the following: The Jones family and the Bell family both entered a medical study for diabetes.The members of Jones family had mostly type 1 diabetes, while Bell family members had type 2 diabetes because they ate junk-food. Given the paragraph above, please answer correctly the following question: Which family had more members that were overweight? Hint: Type 2 diabetes is much more common than type 1 diabetes. Type 2 diabetes occurs when body cells no longer respond normally to insulin. The pancreas still makes insulin, but the cells of the body can't use it. Being overweight and having high blood pressure increase the chances of developing type 2 diabetes. This type of diabetes usually develops in adulthood. However, it is becoming more common in teens and children because more young people are overweight now than ever before.

Dan, a renowned pedologist, visited two farms near his home town. Grape farm had depleted soils and a low crop production, while Fruit farm, having parcels with depleted soils in the past, established an agroforestry system starting a decade ago which helped stabilize soil and increase production. Given the paragraph above, please answer correctly the following question: Which farm used more groundcover plants? Hint: Depleted soils can be protected from soil erosion by groundcover plants such as naturally growing grasses in agroforestry systems. These help to stabilise the soil as they increase cover compared to short-cycle cropping systems. Soil cover is a crucial factor in preventing erosion. Cleaner water through reduced nutrient and soil surface runoff can be a further advantage of agroforestry. The runoff can be reduced by decreasing its velocity and increasing infiltration into the soil. Compared to row-cropped fields nutrient uptake can be higher and reduce nutrient loss into streams.Further advantages concerning plant growth:
