QUESTION TYPE: Necessary Assumption
CONCLUSION: Interactive television will lead to more obesity among North American school-age children.
REASONING: Because there is a strong correlation between obesity and the amount of television children watch.
ANALYSIS: I’m not even sure what interactive television is. It’s a necessary assumption that children will actually watch more television as a result.
Note that this question only establishes a correlation between watching television and obesity, not causation.
___________
- Television is a sedentary activity. But even if diet were a more important cause, this argument could still be true.
- Not necessary. For example: maybe they improved their diets at the same time (thus keeping obesity constant), but they won’t do so now.
- Even if genetics did make a significant contribution, environmental factors such as how much TV a child watches are still a necessary cause of obesity. No one gets fat only because of genetics.
- CORRECT. If they don’t, the argument is worthless. They have no other proposed cause apart from TV to suggest obesity will increase.
- Even if it is only available in 40% of homes, it could still lead to more obesity.
