2. The people followed the principles that Mandela advocated.

As you perhaps know, the clauses underlined above are called adjectival clauses because they qualify the noun in the preceding clause.
In sentence (1) we are able to identify who the man is with the help of the information contained in the clause, who takes another man’s freedom. Similarly, the identity of the principles is revealed by the clause, that Mandela advocated. Without these clauses the listeners will not be able to know who the man is and which principles they are. Who in (1) refers to the man and that in (2) refers to the principles. These words in these sentences are Relative pronouns.
The Adjectival clauses are also called Defining Relative Clauses because they help to define the person or the object referred to.
The whole expression containing the noun phrase and the Relative Clause now acts like a single noun phrase.

Pick out the Defining Relative Clauses and the Noun Phrases they define from the text. Fill in the table given below. One is done for you.
