Assume that the melting of a glacier is taking place at a constant rate of 50 meters per year, and that site A is 1.6 km farther from the ice edge than site B is. Based on this data, and the principle of "space for time substitution," we can assume that the conditions seen at site A in the year 2011 are the same as those that _ seen at site B in _.
