relative pronouns exercise

http://www.english-4u.de/relative_pronouns_ex1.htm

When can we omit a relative pronoun?

The rule is  if the relative pronoun refers back to the subject or object of the relative clause, not the main clause, it may  be omitted.

Example:
The woman (that) I was describing is over there. - fine
The woman told me the story is over there. - not grammatical
