According to a different source, this question refers to the text "The Chinese Civil Service Exam System” by Ichisada Miyazaki.
In this text, we learn that the Chinese civil service examination system originated in Ancient China nearly fourteen hundred years ago. Therefore, it is one of the oldest examination systems in the world.
The system was intended to identify the most capable young men in China, and educate them so that they might become part of the government. However, this was a long, difficult and tedious process, and many students and tutors found useful shortcuts to learning. For example, rapid-study methods were devised, such as compiled collections of examination answers.
The Chinese government was aware of such methods, which were strongly condemned. Students who employed them were failed. The government also issued frequent prohibitions of the publication of such materials. However, the success of the business meant that such prohibitions were often unsuccessful.
An example of an entrepreneur is a person who owns a factory and is able to relocate his operation abroad to save money.
<h3>What is an entrepreneur?</h3>
The entrepreneur is a term to refer to a profession that is based on the direction and management of a company, business or industry. Its purpose is to obtain economic benefits.
On the other hand, entrepreneurs are those who own the organization and its capital and are characterized by seeking the development of their companies by assuming the risks of innovation and investment.
Based on the above, it can be inferred that the most appropriate definition for an entrepreneur is that person who relocates the operation of his factory to another country to save money (option C) because this will bring more profitability to his business.
