Final answer:
The subject of the question is education's impact on students.
Step-by-step explanation:
The correct answer is C. Students / exams / stress.
Education is a social institution through which a society's children are taught basic academic knowledge, learning skills, and cultural norms. Every nation in the world is equipped with some form of education system, though those systems vary greatly. The major factors that affect edu-cation systems are the resources and money that are utilized to support those systems in different nations.
As you might expect, a country's wealth has much to do with the amount of money spent on education. Countries that do not have such basic amenities as running water are unable to support robust edu-cation systems or, in many cases, any formal schooling at all. The result of this worldwide educational inequality is a social concern for many countries, includ-ing the United States.
