Hi there.
A) artillery played a major role in the defeat of the Inca by the Spanish.
I put c on mine and it wasnt right and because money was far from an issue, i would say A.
Gerrymander is the answer.
The Vietnam War ended with the French pulling out and later the U.S. pulling out after the Vietcong (VC) overran Saigon (we lost Vietnam because of MANY reasons but we never sustained a victory) The Korean War ended with a "Cease Fire" from both sides (nobody really won it was more less a draw) Conclusion = Vietnam, We lost Korea, Nobody won nor lost.
