input question: Given the background: In exercises such as weight lifting, skeletal muscle contracts against a resisting force (see Figure below ). Using skeletal muscle in this way increases its size and strength. In exercises such as running, the cardiac muscle contracts faster and the heart pumps more blood. Using cardiac muscle in this way increases its strength and efficiency. Continued exercise is necessary to maintain bigger, stronger muscles. If you don't use a muscle, it will get smaller and weakerso use it or lose it. and the situation: Danny started weight lifting two years ago, he wanted to be bigger. His brother Arnie preferred athletic competitions such as running, so he became a runner. Answer the following question: Which brother didn't increase the size of his muscles????
output answer: Arnie

input question: Given the background: Like water in the ocean, air in the atmosphere exerts pressure that increases with depth. Most gas molecules in the atmosphere are pulled close to Earth's surface by gravity. As a result, air pressure decreases quickly at lower altitudes and then more slowly at higher altitudes. This is illustrated in Figure below . Air pressure is greatest at sea level, where the depth of the atmosphere is greatest. At higher altitudes, the pressure is less because the depth of the atmosphere is less. For example, on top of Mount Everest, the tallest mountain on Earth, air pressure is only about one-third of the pressure at sea level. At such high altitudes, low air pressure makes it hard to breathe and is dangerous to human health. and the situation: Derek is going on a hiking trip with his friends. Before they go they have to decide which mountain they want to go hiking on. Mount Joral is a mountain with a reasonably low altitude. Mount Rook is very high with a much higher altitude. While they are deciding Derek's best friend, Adam, reminds him that he has trouble breathing sometimes. Answer the following question: Which mountain should Derek and his friends climb given they are concerned for Adam????
output answer: Mount Joral

input question: Given the background: Enzymes increase the rate of chemical reactions by reducing the amount of activation energy needed for reactants to start reacting. One way this can happen is modeled in the Figure below . Enzymes aren't changed or used up in the reactions they catalyze, so they can be used to speed up the same reaction over and over again. Each enzyme is highly specific for the particular reaction is catalyzes, so enzymes are very effective. A reaction that would take many years to occur without its enzyme might occur in a split second with the enzyme. Enzymes are also very efficient, so waste products rarely form. and the situation: A scientist is testing chemical reactions. At first he tries mixing two chemicals together at a temperature of 85 degrees Celsius and labels it Trial A. He records the time for the reaction to complete at 2 minutes. Knowing that this isn't the temperature users at home will be combining the chemicals at he tries the reaction again at a more modest 65 degrees Celsius and labels this trial B. Noting this temperature the reaction takes almost 4 times as long which is completely unacceptable, He then gets an idea to add and enzyme designed specifically for these two chemicals and then tries the reaction at the modest 65 degrees Celsius again calling this one trial C Answer the following question: Will adding the enzyme to trial A increase or decrease the rate of the reaction????
output answer: increase

input question: Given the background: Organisms can use different strategies to increase their reproduction rate. Altricial organisms are helpless at birth, and their parents give them a lot of care. This care is often seen in bird species. ( Figure below ). Altricial birds are usually born blind and without feathers. Compared to precocial organisms, altricial organisms have a longer period of development before they reach maturity. Precocial organisms, such as the geese shown below, can take care of themselves at birth and do not require help from their parents ( Figure below ). In order to reproduce as much as possible, altricial and precocial organisms must use very different strategies. and the situation: A female goose now has a large family of chicks, the chicks mostly fend for themselves and can move around almost immediately after being born. A short way away a female dog gives birth to a litter of puppies. These on the other hand are defenseless, cant really move and are blind. They require extensive care from their mother. Answer the following question: Which animal, the baby geese or the puppies, is an altricial species of animal????
output answer:
puppies
