Expert: Some people claim that, since food production has thus far increased faster than population has, there is no need to be concerned about widespread food shortages. These people fail to recognize that the planet' s resources allow for food to be produced at only a few times the current amount, beyond which no increase in production will be possible. Thus, widespread food shortages are inevitable. Which one of the following, if true, most strengthens the expert's reasoning? ['Periodic regional food shortages have occurred at least briefly throughout history.', 'Population will continue to grow at least briefly when food production has reached its maximum level.', "Food resources from the world's oceans will eventually be fully utilized.", "The world's population has recently remained fairly stable because of falling birth rates."]
