The correct answer is D. Creation of the civil service exam
Explanation
The civil service examination system in Imperial China was a testing system designed to select the most suitable candidates to be appointed as Chinese government officials. This system was influenced by the teachings of Confucius, a Chinese philosopher who wrote deeply on governance and meritocracy. This meritocracy system is the longest-lasting in the world, so it can be said that confusion has impacted the Chinese government and society because they were created based on his studies. So, the correct answer is D. Creation of the civil service exam.
Answer:
The Venona Project was an Initiative of the United States government together with the United Kingdom during World War II to intercept and learn about the communications between one of its main allies during that conflict, the former Soviet Union, with its diplomatic, political or military undercover agents; spy networks; or simply influential citizens in the United States.
The project concentrated and deciphered the cablegrams and messages that circulated between Moscow and North America during the war, and potentially "threatened" the national security of the northern country. The project did not get to know each other, or only some American presidents had partial knowledge of it. At first the contents of the messages could not be deciphered, this only happened due to an error of Soviet intelligence, so the content of the messages remained secret until the fall of the socialist camp, in the 1990s, fifty years more late to have been programmed.
The Venona documents comprised three main categories:
- Those that contain reports on the opinions transmitted by American spies.
- Reports of conversations between US and Russian officials.
- Those that provide only a general context or contain little useful information.
A notable case was that of atomic espionage, which led to the execution, in June 1953, of the spouses Julius and Ethel Rosenberg. The evidence that led to the accusation of both was not based on the Venona Project, which was not public and was only known to the secret services, but by statements by Ethel's brother. However, that way he could save himself, even if he pleaded equally guilty.
