Broccoli is a green vegetable that vaguely resembles a miniature tree. It belongs to the plant species known as Brassica oleracea.
It’s closely related to cabbage, Brussels sprouts, kale and cauliflower — all edible plants collectively referred to as cruciferous vegetables. Broccoli is a human invention. It was bred out of the wild cabbage plant, Brassica oleracea . It was cultivated to have a specific taste and flavor that was more palatable to people.
Here's how that worked. Wild cabbage has small flower buds and is a biennial. That means it only flowers every other year.
In a controlled environment, it can be forced to reproduce itself many times. When an offspring of the plant with larger, tastier buds grows, gardeners threw away the less tasty plants and started reproducing from that one.
In future generations, there were further opportunities to get plants with larger, tastier buds. And other genes that make the process easier, such as plants that have a faster growing cycle emerged.
In selecting and reinforcing the traits enjoyed by more people, humans took wild cabbage and cultivated a new kind of plant altogether, broccoli.
Plato, the notorious greek philosopher, had a very specific way of viewing the arts and their meaning to society at the time. To Plato, art was a way of imitation because the artist copied what was infront of him it was a sort of plagerism of reality. He considered the artist's point of view limited and far from the truth, which he was obsessed in attaining.
Even though he thought that art was far from the truth, since it was only a copy of reality, he recognized art's power over human being's emotions. Both plastic arts and music were efficient tools to cause emotional reactions from the viewers, and therefore an effective way of teaching. He thought the influence art had on human emotions could be dangerous at times, that's why it should be used as a didactic instrument.
In conclusion, art was only valuable to Plato if it produced emotional outcome in the subjects exposed to it, and this influence should be used to educate the masses, not to try to represent reality since it could never be completly accurate.
Japan in the later 1800’s was under the control of a military junta led by the Shogun with the emperor with a symbolic role. The major policy of this Shogun was keeping Japan isolated from the rest of the world to stop the destruction of his regime. After 200 years of this (the Dutch had a single trade city in Nagasaki that they traded through) the Americans sent a modern ship into the Japanese harbor of Nagasaki, he was turned away and threatened to open fire on Edo, the capital city. After this show of force, the Japanese conceded and opened up to trade with America, and then later the rest of Europe.
