ANSWER:Step 1 of 3
(a) The observation claims that car accident fatalities on weekends are due to increased alcohol consumption on weekend days, but there might be a different cause for those accident fatalities. For example, perhaps larger groups such as families are more likely to travel together on weekends, rather than individuals commuting to and from work on weekdays. With more people in every vehicle, there would be more incidence of injury or death if there were an accident, and it isn't necessarily due to increased alcohol consumption.
