Question

why do you think the poet ends tje third line and begin the forth with 'I' ? what effect does the repetition create ?​

Answer 1

This repetition helps to bring the poem to a conclusion. It reminds us what's important in the poem – the concept of choosing between two different paths. Then, we get the hesitation of "and I" and the dash. This lets us know that whatever the speaker is about to say next is important.
