I suggest listing all available clauses first and start explaining them afterwards. At the moment it is confusing - are there only 2 available clauses (FROM/WITH)? If there are more, why these 2 are mentioned and not the other ones?

There is also a typo - missing "for" in the statement:
The FROM clause is responsible for defining the scope
