Directions: Read the following passage and answer the given questions: 

Metaphysics is a branch of philosophy that deals with the nature of reality, including the nature of being, existence, and the world. It is concerned with fundamental questions about the nature of existence and the relationship between mind and matter, as well as the nature of causation, time, and causation. Some of the key questions that metaphysics addresses include: What is reality? What is the nature of the self? What is the nature of space and time? What is the nature of causation? What is the nature of existence? 
Reality is the state of things as they actually exist, rather than how they may appear or be perceived. It is the quality of being real, rather than being imaginary or illusory. In philosophy, there are many different theories about what reality is and how it works. Some people believe that reality is an objective, external world that exists independently of our perception of it, while others believe that reality is subjective and that it is created by our perception and interpretation of it. There is no one "correct" answer to this question, and it is something that has been debated by philosophers for centuries.
