Studies have shown that photosynthesis, the process by which plants manufacture life-sustaining proteins from sunlight and carbon, is actually intensified if the level of carbon dioxide in the atmosphere is increased. Since carbon dioxide levels are increased by the burning of fossil fuels and by other human industrial activities, it is obvious that these industrial activities are purely beneficial to agriculture and those of us who depend upon it. The flawed reasoning in the argument above is most similar to that in which one of the following? ['Consistently consuming more calories than one expends inevitably leads to excessive weight gain, so if one wishes to avoid the health problems associated with this condition, one ought to fast periodically.', 'Because a high fiber diet has been shown to be more healthful than a low fiber diet, a diet in which foods with a low fiber content have been entirely replaced by foods with a high fiber content is bound to be even more healthful.', 'It has been shown that one can obtain more vitamins and minerals from fresh fruits and vegetables than from processed fruits and vegetables. One ought, ttherefore, to completely abandon consumption of the latter in favor of the former.', 'Because exercise has been shown to prevent a number of diseases, injuries, and other human ills, clearly no harm, and a lot of good, can come from exercise.']
