Technology developed for military vehicles was used after World War II ended to:
A. create faster airplanes.

B. produce tanks for U.S. allies.

C. manufacture improved cars.

D. create more efficient computers

The nationalists and communists became allies again, because they had a common enemy, Japan, as Japan was invading China at the time. The two sides called for a ceasefire and worked together to stave off the onrushing Japanese invasion.

Hope this helps
