Here is a question about this article: An ancient Indian treatise on statecraft, economic policy and military strategy by Kautilya and Vishnugupta, who are traditionally identified with Chanakya (c. 350-283 BCE). In this treatise, the behaviors and relationships of the people, the King, the State, the Government Superintendents, Courtiers, Enemies, Invaders, and Corporations are analysed and documented. Roger Boesche describes the Arthasastra as "a book of political realism, a book analysing how the political world does work and not very often stating how it ought to work, a book that frequently discloses to a king what calculating and sometimes brutal measures he must carry out to preserve the state and the common good."
What is the answer to this question: What did the Arthasastra say a king must use?
****
So... brutal measures

Here is a question about this article: Certain bacteria form close spatial associations that are essential for their survival. One such mutualistic association, called interspecies hydrogen transfer, occurs between clusters of anaerobic bacteria that consume organic acids, such as butyric acid or propionic acid, and produce hydrogen, and methanogenic Archaea that consume hydrogen. The bacteria in this association are unable to consume the organic acids as this reaction produces hydrogen that accumulates in their surroundings. Only the intimate association with the hydrogen-consuming Archaea keeps the hydrogen concentration low enough to allow the bacteria to grow.
What is the answer to this question: What helps bacteria to survive?
****
So... close spatial associations

Here is a question about this article: In Han government, the emperor was the supreme judge and lawgiver, the commander-in-chief of the armed forces and sole designator of official nominees appointed to the top posts in central and local administrations; those who earned a 600-dan salary-rank or higher. Theoretically, there were no limits to his power. However, state organs with competing interests and institutions such as the court conference (tingyi )where ministers were convened to reach majority consensus on an issuepressured the emperor to accept the advice of his ministers on policy decisions. If the emperor rejected a court conference decision, he risked alienating his high ministers. Nevertheless, emperors sometimes did reject the majority opinion reached at court conferences.
What is the answer to this question: Who was considered to be the supreme judge in Han government?
****
So...
the emperor
