Support or Challenge a fact - Pointing out a false conclusion [1] «Teaching children is easier than teaching adults». It's not completely true to say so. The fact that children are more receptive adults doesn't mean that teaching to them is easier. On one hand, fundamentals disciplines like languages and basic mathematical operations are clearly more transferrable to young learners. But, on the other hand, it is apparent that other more complex issues are unaccessible by children. In my view, most depends on the type of teaching one is going to impart. [2] It appears indisputable that «everyone would benefit from taking more exercise». [3] «The prison population has increased, so more crimes must have been committed». It may be true that an increase of the prison population might be due to the commission of a bigger number of crimes. Notwithstanding, there might be other factors that implicate such conclusion. For example, the legislator might have considered as crime conducts that were not crimes in the past. [4] «Motor cycles should be banned - they're the most dangerous form of road transport». Many people would disagree with such an assertion. Just because motor cycle are dangerous, it doesn't necessarily follow that they should be banned. We'd rather face the problem thanks to a more incisive road safety education.
