There is an inclusive AND and an exclusive AND<br/><br/>How do you know whether it is an inclusive AND or an exclusive AND if they are expressed by the same word?<br/><br/>I posted this earlier:<br/><br/>May reduce onset risk or symptoms of metabolic syndrome and diabetes.<br/><br/> Reduce the onset risk of any of the two diseases and reduce the symptoms present in both diseases?<br/><br/> and is used both as an "exclusive and" and an "inclusive and", which makes the sentence a poor one, agree or not?
