Hi Mohammed, Say: Experts say cases involving kidnap victims, who are found alive years after they have GONE MISSING, are rare. 1. People "go missing" 2. Using commas to enclose the subordinate clause makes the writing much easier to read. 3. A subordinate clause is one which can be entirely removed from the sentence and the sentence will still make perfect sense. Hope this helps, Kind regards, Josephine

It is only necessary to say" kidnap victims FOUND alive regards, Theresa
