Explanation:
Clauses are group of related words containing a subject and a verb and that can be divided into two types: 1) Dependent or Subordinate: when they do not express a complete thought on their own, and therefore can not stand alone as sentences, or 2) Independent: when they express a complete idea on their own.
Clauses number 1 and 3 are dependent clauses because they do not express a complete idea and does not make any sense standing alone, and should always be placed next to an independent clause.
