Problem: Given the question: I read this background article the other day: A major use for petroleum products is fuel for cars, trucks, airplanes, trains, and other vehicles. The chemical used are usually a mixture of compounds containing several carbon atoms in a chain. When the material is ignited, a massive amount of gas is created almost instantaneously. This increase in volume will move the pistons in an internal combustion engine to provide power. A jet plane works on a similar principle. Air comes into the front of the engine and mixes with the jet fuel. This mixture is ignited and the gases formed create a lot of pressure to push the plane forward. The idea can be seen even more clearly in the case of a rocket launch. The ignition of the fuel (either solid-state or liquid) creates gases produced under great pressure that pushes the rocket up. I am facing a new situation today: Two sister countries used petroleum in different ways. Norway used it to make plastics, while Sweden used it for fuel. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which country used less fuel to power cars?
++++++++++++++++++++++++++++++++
The answer is:
Norway
input question: I read this background article the other day: A comet tailand comaare features visible in comets when they are illuminated by the Sun and may become visible from Earth when a comet passes through the inner Solar System. As a comet approaches the inner Solar System, solar radiation causes the volatile materials within the comet to vaporize and stream out of the nucleus, carrying dust away with them. Separate tails are formed of dust and gases, becoming visible through different phenomena; the dust reflects sunlight directly and the gases glow from ionisation. Most comets are too faint to be visible without the aid of a telescope, but a few each decade become bright enough to be visible to the naked eye. I am facing a new situation today: This year thee comets would be of interest, comet A, comet B, and comet C. Comet A and comet B would enter the inner solar system. But comet C would not enter the inner solar system. Moreover, comet A is categorized as a bright comet, but comet B is categorized as a faint comet. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which comet's tail would not be visible from earth, comet A or comet C????
output answer: comet C
I read this background article the other day: Air pollution is harmful to human beings and other living things. About 22 million people die from air pollution each year. Breathing polluted air increases the risk of developing lung diseases such as asthma and lung cancer. Breathing bad air also increases the chances of dying from other diseases. Children are most likely to be affected by air pollution. That's because their lungs are still developing and growing. Children also take in more air for their size than adults do. Some air pollutants damage the environment as well as the health of living things. The type of damage depends on the pollutant. Air pollution can also harm the environment. I am facing a new situation today: Two sister cities had different environments. Shanghai had big problems with air pollution while Berna took very good care of the surrounding environment and air quality. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which city had people at decreased risk of dying from other diseases?
----
Answer: Berna
Q: I read this background article the other day: A baby is born with zones of cartilage in its bones that allow growth of the bones. These areas, called growth plates , allow the bones to grow longer as the child grows. By the time the child reaches an age of about 18 to 25 years, all of the cartilage in the growth plate has been replaced by bone. This stops the bone from growing any longer. Even though bones stop growing in length in early adulthood, they can continue to increase in thickness throughout life. This thickening occurs in response to strain from increased muscle activity and from weight-lifting exercises. I am facing a new situation today: John was a relatively thin and bone-y child when he was younger. He would often get bruises and was prone to breaking bones. As an adult however he does lots of weight lifting and hasn't broken a bone yet. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Will lifting weights likely increase or decrease bone thickness?
A: increase
Question: I read this background article the other day: Start right above point on the temperature axis and follow the red line vertically. At very low pressure, the particles of the substance are far apart from one another and the substance is in the gas state. As the pressure is increased, the particles of the substance are forced closer and closer together. Eventually the particles are pushed so close together that attractive forces cause the substance to condense into the liquid state. Continually increasing the pressure on the liquid will eventually cause the substance to solidify. For the majority of substances, the solid state is denser than the liquid state and so putting a liquid under great pressure will cause it to turn into a solid. The line segment represents the process of sublimation, where the substance changes directly from a solid to a gas. At a sufficiently low pressure, the liquid phase does not exist. The point labeled is called the triple point . The triple point is the one condition of temperature and pressure where the solid, liquid, and vapor states of a substance can all coexist at equilibrium. I am facing a new situation today: Dan is conducting a research to see how a substance behaves in varying pressure. First, he selects a gaseous substance in very low pressure. He calls it as case A. Then he increases the pressure. He calls it case B. Finally, he increases the pressure even further. He calls it case C. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which case would see less distance between particles, case B or case C?
Answer: case C
Please answer this: I read this background article the other day: One of the main causes of extinction is introduction of exotic species into an environment. These exotic and new species can also be called invasive species or non-native species . These non-native species, being new to an area, may not have natural predators in the new habitat, which allows their populations to easily adapt and grow. Invasive species out-compete the native species for resources. Sometimes invasive species are so successful at living in a certain habitat that the native species go extinct ( Figure below ). I am facing a new situation today: India decided to introduce several exotic species into their environment, while Singapore was very protective of its native species. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which country introduced more non-native species to the environment?
++++++++
Answer:
India
