Explanation:
Marian Anderson was an American classical singer who became popular for her open concert at the Lincoln Memorial. <u>This event broke the barrier between the white people and the black people.</u>
Since she hasn't really faced such a huge crowd in her entire life, she stated, <em>"I had become, whether I liked it or not, a symbol, representing my people. I had to appear."</em> By saying this, as a black woman herself, she was able to bring dignity to people of her kind. She proudly sang, "My Country, 'Tis of Thee," a patriotic song which attracted around 75,000 people (both whites and blacks).
