Final answer:
The best scenario illustrating causation is when taking longer showers results in a higher water bill, demonstrating a direct cause-and-effect relationship.
Step-by-step explanation:
The scenario that best shows causation is when I take long showers, my water bill is higher than usual. This is an example of a direct cause-and-effect relationship where the action of taking longer showers directly causes an increase in the water bill, assuming all other factors are constant.
Causation differs from correlation, which merely shows that two factors are related. Correlation does not imply that one variable causes the change in another. An example of correlation would be option E: there is a strong correlation between the type of snacks a person eats and scores earned on the SAT. While there might be a relationship, it doesn't necessarily mean one causes the other. Similarly, option A: people who drive to school are less likely to spend holidays with family could be influenced by numerous variables, and there isn't a clear cause-and-effect relationship.
