to live
Explanation:
The poem uses the refrain on 'to live' to show the insistence of the poet on will to life and to keep going on despite hardships that might pull her down.
The hopefulness of the poem is also accentuated with this refrain on 'to live' which reaffirms life. What lies ahead in life is presented as life and what is behind is what should be moved on from.
<u>Hence, it becomes a continuous process 'to live' and thus the line serves as a refrain.</u>
The third choice is the answer.
A semicolon (;) is used to combine two separate sentences with a similar topic. The two sentences that are trying to be combined are "My Uncle Bill has such a beautiful voice" and "many couples has asked him to sing at their wedding". Since these two sentences share a similar topic, a semicolon would be best.
Have an awesome day! :)
