Problem: Given the question: I can use this background: 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. Now, I have a new situation: John wanted to invent a machine. To that end, he devised an experiment in which he used three components, comp A, comp B, and comp C. Comp A was a machine that applied force over a shorter distance. Comp B was also a machine, but it applied force over a longer distance. Comp C was not a machine. Answer this question please: Which component would increase the force applied, comp A or comp B?

The answer is:
comp A
input question: I can use this background: When a solid substance is involved in a chemical reaction, only the matter at the surface of the solid is exposed to other reactants. If a solid has more surface area, more of it is exposed and able to react. Therefore, increasing the surface area of solid reactants increases the reaction rate. Look at the hammer and nails pictured in the Figure below . Both are made of iron and will rust when the iron combines with oxygen in the air. However, the nails have a greater surface area, so they will rust faster. Now, I have a new situation: John is trying to figure out how the shape of an object affects how it reacts with other elements. For that, he chose two objects, both made of the same element - object A and object B. Object A has a larger surface area, but object B has smaller surface area. He let these objects to react with other reactants to see how the processes work. Answer this question please: Which object would have higher reaction rate, object A or object B????
output answer: object A
I can use this background: Klinefelter's syndrome is caused by the presence of one or more extra copies of the X chromosome in a male's cells. Extra genetic material from the X chromosome interferes with male sexual development, preventing the testicles from functioning normally and reducing the levels of testosterone. Triple X syndrome (trisomy X) results from an extra copy of the X chromosome in each of a female's cells. Females with trisomy X have a lower IQ than their siblings. Turner syndrome results when each of a female's cells has one normal X chromosome and the other sex chromosome is missing or altered. The missing genetic material affects development and causes the characteristic features of the condition, including short stature and infertility. Now, I have a new situation: Two brothers born three years apart were very different. Jim had no genetic abnormalities, while Danny had Klinefelter's syndrome. Answer this question please: Which brother didn't have any interference from the extra copies of the X chromosome in his cells?
----
Answer: Jim
Q: I can use this background: Inbreeding is the production of offspring from the mating or breeding of individuals or organisms that are closely related genetically.[2] By analogy, the term is used in human reproduction, but more commonly refers to the genetic disorders and other consequences that may arise from expression of deleterious or recessive traits resulting from incestuous sexual relationships and consanguinity. Inbreeding results in homozygosity, which can increase the chances of offspring being affected by deleterious or recessive traits.[3] This usually leads to at least temporarily decreased biological fitness of a population[4][5] (called inbreeding depression), which is its ability to survive and reproduce. An individual who inherits such deleterious traits is colloquially referred to as inbred. The avoidance of expression of such deleterious recessive alleles caused by inbreeding, via inbreeding avoidance mechanisms, is the main selective reason for outcrossing.[6][7] Crossbreeding between populations also often has positive effects on fitness-related traits,[8] but also sometimes leads to negative effects known as outbreeding depression. However increased homozygosity increases probability of fixing beneficial alleles and also slightly decreases probability of fixing deleterious alleles in population.[9] Inbreeding can result in purging of deleterious alleles from a population through purifying selection.[10][11][12] Now, I have a new situation: Two farmers both had ten cattle each. Bill decided to interbreed his cattle, but James didn't because he knew about the consequences. Two years later Bill had 12 cattle and James had 30 healthy cattle. Answer this question please: Which farmer used consanguinity to breed his cattle?
A: Bill
Question: I can use this background: You don't have to suffer through an infection to gain immunity to some diseases. Immunity can also come about by vaccination. Vaccination is the process of exposing a person to pathogens on purpose so the person will develop immunity to them. In vaccination, the pathogens are usually injected under the skin. Only part of the pathogens are injected, or else weakened or dead pathogens are used. This causes an immune response without causing the disease. Diseases you are likely to have been vaccinated against include measles, mumps, and chicken pox. Now, I have a new situation: Two families thought differently about vaccinations. Dean family vaccinated their children while Moore family didn't. Answer this question please: Which family exposed their members to pathogens on purpose?
Answer: Dean
Please answer this: I can use this background: Weather conditions include air temperature, humidity, wind speed and direction, and precipitation. Weather is temporary. People in many states have the joke, "if you don't like the weather, wait five minutes and it will change." One way to change the weather is to have a different air mass move over the region. Interactions between air masses bring about a lot of weather. For example, thunderstorms and tornadoes form along a front. A front is where air masses meet. Fronts can bring about blizzards, thunderstorms, tornadoes and other types of weather. Weather prediction is much better than it was in past years. This is due in part to information from satellites. Climate is the long-term average of weather. The climate of a location depends on its latitude, position relative to the atmospheric circulation cells, position on a continent, altitude, and position relative to mountains. Areas with roughly the same climate make up a climate zone. The organisms that live within a climate zone create a unique biome. Earth's climate has changed throughout the planet's history. Earth was frigid at the end of the Pleistocene ice age, but has been warming since then. Since the Industrial Revolution the pace of warming has increased. In the past few decades the rate has really intensified. This is related to greenhouse gas emissions, primary from fossil fuel burning. The destruction of forests also increasing warming. The effects of global warming are already being seen. Treaties and voluntary actions are needed to reduce emissions to lessen the amount of global warming that will take place in the future. Now, I have a new situation: Two neighbors attended the same school. Mike learned about biology while Dan learned more about the weather. They both were among the best in the school. Answer this question please: Which person read less about precipitation?
++++++++
Answer:
Mike
