The pair representing a causation relationship is the temperature at a football game and the number of hot drinks sold, as the temperature can directly influence drink preferences.
The question poses a situation where we must identify which pair best represents a causation relationship. Out of the options given, option R, the relationship between the temperature at a football game and the number of hot drinks sold, is the pair that best represents a causation relationship. This is because the temperature at a game can directly influence spectators' preferences for warm beverages.
For example, as the temperature drops, it is logical that more spectators will buy hot drinks to stay warm, illustrating a positive correlation. Conversely, if the temperature were high, the sales of hot drinks would likely decrease, showing a negative correlation. This relationship here is not merely a coincidence but a causal one where one variable (temperature) causes a change in the other variable (hot drink sales).
