If there is only one country in the world, this matter will be relatively simple, and no matter how much it costs, it will be borne by this country in the end. But the problem is that many countries in the world have very different national conditions and histories. How to distribute this huge ticket among countries has become the core issue of global warming negotiations. All countries, all emission reduction commitments, will eventually have a price tag. The more promises, the higher the price.

25. From the perspective of the history of landscape painting, although the emperors of the Northern Song Dynasty and the Southern Song Dynasty were all surnamed Zhao, their painting styles were quite different, and they were usually divided into two parts: the Ming Dynasty was Zhu Yuanzhang's world, the Qing Dynasty's surname was Ai Jianjue Luo, and the rulers were neither a family nor a surname. The time span was more than 540 years, but they were often put together. This is because political history and art history are not necessarily parallel. In other words, the mainstream of painting history in Ming and Qing Dynasties is almost completely influenced by the painting style in Yuan Dynasty, with strong copy and weak creativity, unlike the painting in Song Dynasty, which has significantly different characteristics.

The following statement is consistent with the original text:

A. the emperor of the song dynasty rarely directly intervened in painting creation.
