He uses repetition to emphasize change on the horizon for people who are struggling.
Step-by-step explanation:
In his Inaugural Speech given on January 20, 1961, President John F. Kennedy expresses his desire to achieve liberty and freedom for everyone. He also reiterates the need to oppose any foe that may hinder the path to liberty.
In the given excerpt, President Kennedy uses parallelism in the lines "To those old allies.. to those new states.... to those people..." where he talks of the need for change for those struggling. This use of repetition emphasizes the hope for change on the horizon.
Thus, the correct answer is the third option.
