Think about the following:
Working out makes your muscles sore & painful
Pain is a bad thing to experience
Therefore working out is bad for you.
Obviously although this argument makes sense technically, science has proven that working out is actually good for your body, so it is not factually sound.
A cow fart contains methane gas
Methane is a large contributer of global warming
Cows are the cause of global warming.
This argument is a tricky one. Although technically factual, cows do contribute to global warming because of methane gas, this is undeniable, it is not the only reason and therefore we cannot single it out. More clarification would be needed to make this argument totally sound.
McDonald’s sells apple slices
Apples have nutrients which are good for you
McDonald’s is good for your health
This argument is sound by form, but the content it holds has been disproved to an extent. Although apples are good for you, it is incorrect to jump to the conclusion that McDonald’s is as well. It has been scientifically proven that a large amount of their food is not beneficial to one’s health.
