Answer: Metaphor
Explanation: Metaphors represent or symbolize something in a way that it is not literally true. The thorns of life for example, meaning the bad things that happen to everyone at least at some point in their lives. Bleeding symbolizes suffering even though you do not actually bleed when you go through trouble in your life.
I should like to see the time come when women shall help to make the laws. I should like to see . . . the ballot, in the hands of women.
An ellipsis is used to delete unimportant words or phrases in a quote. In this case, the words "that whiplash" was replaced with the ellipsis. It is not necessary to understand the meaning of the sentence. Sentence 1 is not clear because it just states he wants to see the ballot, not that he wants to see it in the hand of women, which is his main point. Sentence 3 is incorrect because nothing was omitted. In Sentence 4, it is not clear who shall help make the laws, which is his main point.
Maybe put it in parenthesis or maybe wait until the next paragraph. I'm not sure it all depends on your teacher.
