The Tang Dynasty of China was notable for returning civil-service exams to use and creating what type of society based on ability rather than birthrights?​

Answers

The Tang Dynasty of China was notable for returning civil-service exams to use and creating the following type of society based on ability rather than birthrights:

The type of society it created was a society based on merit. Yes, a society based on personal merit, knowledge, and progress, instead of birthrights.In Imperial China times, Civil Service Examinations were a requirement to choose the appropriate candidate to occupy an office in the government.

During the Teng Dynasty, the government changed its military approach to a more type of bureaucratic system.This new system was run by Chinese civilians that had the knowledge and credentials to occupy these positions.

We conclude that one consequence of the civil service examination system used by the Tang dynasty was that Chinese government officials were selected based on their skills and abilities rather than their family history.

When Dave and his friend sit down to rewrite the budget, how realistic is it? Could the budget be balanced and changed that easily? Why or why not? Why do we need a balanced budget?

Answers

1. It is not realistic to rewrite the budget to balance it unless there was the padding of the initial draft of the budget with in-built cushions.

 

2. A budget could not be easily balanced and changed unless it is still in the draft stage. Once a budget is approved, the budget holders perform within the budget constraints.

 

3. Whether a budget variance is favorable or unfavorable, some significant variances require investigation to discover the causes and enable remedial actions.

 

4. Thus, a balanced budget shows that the expenditures and revenues during the budget period are equal. A balanced budget is not always realistic.
