Analyze each of the following arguments in terms of “antecedents” and “phenomena” to show how they follow the pattern of the method of residues:

Analyzing more than forty years of weather data, climatologists at the National Oceanic and Atmospheric Administration in Boulder, Colorado, recently found that the daily temperature range—the difference between the daytime maximum and the nighttime minimum temperatures—at 660 weather stations in the continental United States fluctuates in a very puzzling manner: the variation of the temperature range over the course of a week, in some regions, does not line up with any natural cycles that can be detected.

The average temperature range for the weekends (Saturday, Sunday, and Monday) varied from the average temperature range for weekdays (Tuesday, Wednesday, Thursday, and Friday)! Fluctuations in the daily range can be caused by natural factors; storm systems moving across an area, for example, can cause such fluctuation—but there are no natural factors known to fall consistently on certain days of the week.
The precise cause of this extraordinary pattern is not clear. However, contend the researchers (Piers M. de F. Forster and Susan Solomon), the only possible explanation for this weekend/weekday disparity is human activity and the atmospheric pollutants such activity creates.
