Final answer:
A cease-fire is a temporary stoppage of war, where sides agree to stop fighting, but the correct term is not listed among the provided words. The given quote does not provide Eisenhower's steps to win the war.
Step-by-step explanation:
The word that best fits the definition of a cease-fire is not given in the list provided. A cease-fire refers to the temporary stoppage of a war or armed conflict where the sides in dispute agree to stop aggressive actions. This term typically implies a halting of hostilities between combatants in agreement to pause fighting and typically marks a step towards the negotiation of a more permanent peace agreement. The words listed (Go, Edge, Ingenuity, and Nuit) do not represent this concept.
Referring to the excerpt, "I'm quitting work now, 7:30 p.m. I haven't the heart to go on tonight." - Dwight D. Eisenhower, The Eisenhower Diaries, there is no direct mention or implication about what Eisenhower identifies as the most important steps to take to win the war in this sentence alone. If you have more context or another part of the diaries indicates Eisenhower's thoughts on winning the war, please provide it so we can assist you better.
