Answer:
D. Nurture.
Step-by-step explanation:
Taken from the Second Inaugural Address of President Abraham Lincoln, the given passage details the optimism, the aim of the American people and the nation as a whole. His focus was on the need to keep the faith of unity, peace and recuperation from the many wars and fighting that America had experienced. President Lincoln also requested, implored and encouraged the American people to keep working towards a more peaceful existence and at the same time help those in need.
The use of the word "cherish" in this context means to nurture, to help grow and improve the "just, and a lasting peace, among ourselves, and with all nations."
