A few major inventions that were invented after World War II were the following:
- Computers. These were invented in 1971 by Ed Roberts.
- Medical penicillin. This was invented in 1941 by a group of medical professionals.
- Jet engines. In the closing months of the war, jet engines came to the force. The first technology was developed in 1939 to 1945, and is now used all over the globe.
I think its C. they staged a counter-demonstration. I may be wrong.
The answer would be : a convention.
Hope this helps !

Similarities between Japanese and European feudalism include a social system of various classes with little possibility of mobility from one class to another, the proffering of allegiance in exchange for protection, a warrior class with a code of honor and a peasant class tied to the land. Both societies also had clergy that functioned outside the normal feudal system.
Free land (well they had to pay like 10 cents), and gold (the gold rush).
