The bow and arrow was invented in Woodland.
So your answer is D.
The story of the 47 Ronin is a real historical account of Japan. Its author wanted to reinstate in the modern times that there is more to human life than the repetitive existence and work. People must find in themselves a deeper sense of existence, a deeper meaning in life, an unending adherence to a long history of culture and loyalty. The Japanese ronin existed in an era in Japan where there were no more wars to fight. The samurai was regarded as a warrior class that earns deep respect from the people. In fears that the Japanese spirit might be slowly slipping away, it is very timely that the story of the 47 Ronin is retold. Should the author have existed in feudalistic Europe, the story would have been different because in Europe, treatment of knights is very different. The knights were given land titles to govern. Knighthood is only given to the noblemen. It is more of a status quo rather than a binding story for loyalty and respect.
