In trying to reduce the amount of fat in their diet, on average people have decreased their consumption of red meat by one-half in the last two decades. However, on average those who have reduced their consumption of red meat actually consume substantially more fat than those who have not. Which one of the following, if true, most helps to resolve the apparent discrepancy described above? ['Higher prices over the last two decades have done as much to decrease the consumption of red meat as health concerns have.', 'People who reduce their consumption of red meat tend to replace it with cheese and baked goods, which are richer in fat than red meat.', 'People who reduce their consumption of red meat tend to consume as much of other foods that are high in fat as do those who have not reduced their consumption of red meat.', 'Many more people have reduced their consumption of red meat over the last two decades than have not.']
