Final answer:
The sentence in question is a complex sentence because it includes one independent clause and multiple dependent clauses that add additional information.
Step-by-step explanation:
The sentence 'The award-winning writer Maya Angelou composed "On the Pulse of the Morning" at the request of President Bill Clinton and recited the poem at his inauguration in 1993.' is a complex sentence.
This is because it contains one independent clause ('The award-winning writer Maya Angelou composed "On the Pulse of the Morning"') and one or more dependent clauses ('at the request of President Bill Clinton' and 'and recited the poem at his inauguration in 1993').
Which cannot stand alone as a complete sentence.Complex sentences are used for depth and detail in writing, allowing the author to connect related ideas with a subordinating conjunction that gives one idea more importance than the other.
