Rene Descartes ( 1596 - 1650 ) was very important scientist. He invented the Cartesian coordinate system. He considered mathematics like the basis to all sciences. Descartes partially agreed with Copernicus` theory about the Heliocentric system. He had his theory - "theory of the vertex". because he was scared of the Catholic church, he didn`t totally agree with the Heliocentric system. He also had his "Method of doubt": Can`t be doubted = certainty = truth.
Answer: b. He proposed that through the use of reason and doubt individuals may arrive at understanding.
Crete is the best option :)
The answer is option 3: A technique for making porcelain was perfected.
The art of making porcelain prospered in both periods. A lot of innovations were made in forms, glazes, decorative techniques methods of production and kiln technology.
During the Tang Dynasty, porcelain kilns were constructed all over the country and a type of vessel with molded decorations on it became very popular, which was made using an "upside down" and the coal was used as kiln fuel.
By the Song period, the manufacturing process was standardized (base-making, glazing, ingredient control, and temperature maintenance). In addition, the industry was divided into five types of kilns that had several features for glaze coloring and pattern design.
The achievement of rice as an ideal harvest for South Carolina was helped by the formation of water system frameworks that enabled workers to surge and deplete the fields. By 1700, tobacco, rice, and indigo were the most critical fare products of Maryland, Carolinas, and Virginia.
Day 1:
Today, I went to school. I woke up when the rooster awoke me, and I first did all my chores. Afterwards, I had breakfast and walked to school. The teacher made us copy some words on our slates, and spell them out loud. Everyone did really well. For lunch, I went to the river with my friends. The teacher did not assign homework, and we got to go home early.
Day 2:
Today my chores were more difficult, because we are beginning to get ready for winter. At school, the teacher made us memorize some poems, and I was asked to help the smaller children with the words they did not know. I also stayed after school to help the teacher clean the classroom.
Day 3:
Today was Friday, which meant that we would study science. Therefore, we went to the river, and we looked at the fish and the other animals that lived there. The teacher then sat us on a circle in the forest and she talked to us about how all nature is connected. We then had lunch and came back to the classroom. Once in class, we wrote a paragraph about winter, and then we went home.
