Former South African president and civil rights advocate Nelson Mandela dedicated his life to fighting for equality—and ultimately helped topple South Africa's racist system of apartheid.
Idiom "Hold your horses"
Simile "As red as a tomato"
Hyperbole "This food is hotter than the sun"
Metaphor "He was a walking encyclopedia"
Alliteration "Peter pepper picked a pickled pepper"
Personification "The sun smiled at me"

The conjunction that bestfits the run-on sentence is

The rhythm of the excerpt supports the theme of the poem, because the rhythm is consistent, and Poe celebrates the simplicity of young love.

At this point in the poem, we still don't see anything bad that is about to happen. He is just talking about a young woman whose only care in the world is to love the narrator, and be loved by him. Later on in the poem we will see why that is impossible, but here, there is still no word about that.
I hoped this helped! :)
