The correct answer is A. The innovations that resulted from the World War II were the jeep, the landing craft and the blood bank.
JEEP: The history of Jeep officially began in 1941 when Ford and Willys-Overland began manufacturing Jeep vehicles in their factories in Ohio, United States. But it was 1938 when it was planned how the Jeep was going to be. In 1940, the United States Army asked American vehicle manufacturers to submit bids for a small, four-wheel drive vehicle that could serve different tasks and missions, with outstanding performance, stability, autonomy, reliability and performance capabilities. maintenance. This request became more urgent when the Axis forces began to obtain victories in Europe and North Africa, for which reason the US Army would accept only proposals that could be fulfilled within a period of 49 days.
When the first Jeep was created there was not what today is known as 4x4 segment in the field of trucks. The main clients of the Jeep were the Allied Forces that tried to impose peace in a world torn apart by the battles of World War II. It was conceived as the substitute for the motorcycle used to carry messages between the different units of the US Army, however, only a few of the first Jeep vehicles manufactured until 1945 remained in the United States. Instead, hundreds of thousands of these vehicles were sent to Europe, Africa and the Pacific.
LANDING CRAFT: Landing craft are small or medium-sized ships used to transport a landing force composed of troops, vehicles and equipment, from the sea to the coast during an amphibious assault. They are indispensable in amphibious actions, such as those carried out in Normandy and the Pacific Islands during the Second World War. This time was the high point of the use of landing craft, with a significant amount of different designs produced in large quantities by the United States and the United Kingdom.
BLOOD BANK: A blood bank is the place where blood and blood components are stored and processed. Blood banks are located both in the transfusion centers and in the hospital transfusion services. The centers of transfusion are centers in charge of the extraction and verification of the human blood or its components, whatever their destiny, and of their treatment, storage and distribution when the destiny is the transfusion. Transfusion services are care units located in hospitals, where blood components are stored and compatibility tests and other immunohaematology tests are performed for their transfusion to patients who require it.
