What's the difference between: 'his question didn't include a link on Yahoo answers? ' and 'his question didn't contain a link on Yahoo answers? ' (I want to say there wasn't a link in his question on Yahoo answers).
Someone mentioned there are subtle differences, but just can't tell what they are, so I am wondering that you guys here might have the answer. please help me out. thanks folks!
