Two factors that helped to contribute to the scientific revolution in Europe in the mid 1500s were economic expansion and also the translation of ancient Greek texts into the vernacular. Economic development during the Renaissance period led to a new need for engineers, architects, and inventors to help to develop society which led to further development of scientific thought. Additionally with the rediscovery of Ancient Greek texts, thinkers of the time began to further develop empirical ways of thinking based in Aristotelian methods of logic and reasoning. hope it helps :)
It was the "Open Door Policy" that was the name of the trading policy that Secretary of State John Hay initiated with China and the European nations that already had a presence there, since the US wanted to benefit from trade with China as well.

And below each division, their works are given. Aswecan were that, each of the organ is at same height which shows that they are practicing equal powers and they don't interrupt in each others work.
They practice the system of <u>Checks</u><u> </u><u>and</u><u> </u><u>Balances</u> to ensure that none of the organ is enjoying and grabbing too much.
So, the most appropriate option is:

Checks and balances system.
And, we are done !!
