Hi TMH

Have a look at these definitions and the accompanying example sentences:

- involve
- consist of
- consist in
- contain

After you've done that, I would suggest you try writing a few sentences of your own, and then post them here for comment.

Hi Yankee,
Thanks for responding me. It's quite difficult for me to tell them apart. However I'll try to do according to your suggestion.
