The following pairs of variables are all strongly correlated (positively or negatively, as indicated), but for only some of them is there a cause-and-effect relationship between the variables. Which of the pairs has a cause-and-effect relationship? A. The heights of women's hemlines and the Dow-Jones Industrial Average (+) B. Among US adult males, weight and the frequency of heart attacks (+) C. Home heating bills and the price of take-out food (+) D. The weight of an automobile and its gas mileage (-) E. In US cities in one year, number of sunny days and per capita income
