input question: John designed a hypothetical lever that would have ideal mechanical advantage. He labeled the lever as lever A. He then wanted to compare this lever with a real world lever, which he labeled as lever B. He intended to use these levers to increase force. Given the paragraph above, please answer correctly the following question: Which lever would have greater mechanical advantage, lever A or lever B? Hint: The Table above includes the ideal mechanical advantage of each class of lever. The mechanical advantage is the factor by which a machine changes the input force. The ideal mechanical advantage is the increase or decrease in force that would occur if there were no friction to overcome in the use of the machine. Because all machines must overcome some friction, the ideal mechanical advantage is always somewhat greater than the actual mechanical advantage of the machine as it is used in the real world.???
output answer: lever A

input question: There are two planets, Glarnak and Bornak, that share the same atmospheric composition. The planets have nearly identical ecosystems and topography. The main difference between the two planets is the level of global warming on each planet. Glarnak is experiencing a strong impact from global warming. Bornak, though, is experiencing practically no effects of global warming. Given the paragraph above, please answer correctly the following question: Which planet probably produces more carbon dioxide? Hint: Pollutants also affect the atmosphere through their contribution to global warming. Global warming is an increase in the Earth's temperature. It is thought to be caused mostly by the increase of greenhouse gases like carbon dioxide. Greenhouse gases can be released by factories that burn fossil fuels. Over the past 20 years, burning fossil fuels has produced about three-quarters of the carbon dioxide from human activity. The rest of the carbon dioxide in the atmosphere is there because of deforestation, or cutting down trees ( Figure below ). Trees absorb carbon dioxide during cellular respiration, so when trees are cut down, they cannot remove carbon dioxide from the air.???
output answer: Glarnak

input question: David is interested in how electricity works. One day he had two electric charges to investigate, charge A and charge B - both of the charges were negative. He also had two electric fields, field C and field D. He noticed that electric charges were moving from field C to field D. Given the paragraph above, please answer correctly the following question: Would field C have higher or lower potential energy than field D? Hint: Electric potential energy comes from the position of a charged particle in an electric field. For example, when two negative charges are close together, they have potential energy because they repel each other and have the potential to push apart. If the charges actually move apart, their potential energy decreases. Electric charges always move spontaneously from a position where they have higher potential energy to a position where they have lower potential energy. This is like water falling over a dam from an area of higher to lower potential energy due to gravity.???
output answer: higher

input question: John is very health conscious. He works out regularly, and maintains balanced diet. But his friend Keith doesn't care much about health. He indulges in fast foods, and never exercises. As a result, Keith has type 2 diabetes, but John is free from diabetes. Given the paragraph above, please answer correctly the following question: Who is more likely to be overweight, John or Keith? 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.???
output answer:
Keith
