The correct answer to this open question is the following.
Although there are not options provided, we can say that the rulers of the Han Dynasty set up a system to choose government officials on the basis of merit, knowledge, and experience, rather than the mere right of birth.
That is why government officials were chosen during the Han dynasty, considering that those factors had more merit to occupy an office in the government. So the Hang dynasty where the first to introduce the idea of having a civil service test or examination to choose their officials. This was the best way to select the right kind of people to lead the nation. They offered education to people that aspired to be one of those officials, understanding that this would be a privilege, not a right.
Answer:
The answer is double blind experiment.
Explanation:
In a double blind experiment, neither the researchers nor the participants are aware about which group is receiving the experimental treatment. This is done in order to prevent biases in the participants' judgment (the placebo effect), and prevent the researchers from giving accidental cues.
The greatest advantage of double blind studies is they have greater reliability and validity than other types of studies.
