By Maya Angelou asking people to go back to their dreams, referencing Martin Luther King Jr.'s "I Have a Dream" Speech, she created what

Allusion.

Explanation:

"On the Pulse Of Morning" is a poem written and recited by Maya Angelou on the eve of the first inauguration of President Bill Clinton. Maya Angelou was the second poet to recite a poem on a presidential inauguration and also the first woman and African American.

In her poem she called the people to go back to their 'dreams.' The call of going back to the dream is used in reference to the speech 'I Have a Dream' delivered by Martin Luther King Jr. By referencing to the 'Dream' of Martin Luther, Maya has created an allusion.

An allusion is a literary device that is used to indirectly use reference of a person, place, thing, or idea in a literary work. It is known as referencing of other's literary work in a literary work. When a writer uses an allusion, he/she does not elaborate much on the topic but expects his audience to understand the idea that he/she wants to convey.

By referencing Martin's 'dream' in her poem, Maya is urging her audience to dream the dream that Martin had for America, of equality and brotherhood.

Thus the correct answer is an allusion.
