1.In the Kellogg - Briand Pact, countries agreed to give up war except for self-defense.
2.France and Britain used reparations while ___Germany to repay to the U.S. The Dawes Plan lent money to Germany and reduced its war debt.
3.The spread of the automobile and new electric appliances contributed to economic prosperity. Assembly-line production lowered prices, while installment purchase plans made buying goods easier.
Hopefully this helps. I made the words that fit in the blank spots bold. I have to say that I am not to sure as to it is Installment Plans, or Installment Purchase Plans.
