text: ### Theory:
  
  Anything that is not straight is referred to as a curve.
  There are different types of curves. Some of which are:
  • Simple curve
  • Non-simple curve
  • Open curve
  • Closed curve
  
  A curve that does not cross itself is called a simple curve.
  
  A curve that crosses its own path is called a non-simple curve.
  
  An open curve is a curve whose endpoints do not meet at any point. It has two endpoints.
  
  A closed curve is a curve, which has no endpoints and enclosed an area.
  
  A closed curve contains $$3$$ parts. They are:
  • Interior of the curve
  • Exterior of the curve
  • Boundary of the curve
  
  1. Interior of the curve:
  
  The inside / inner region of the curve is referred to as the interior of the curve. In the above figure, point $$A$$ lies on the interior of the curve.
  
  2. Exterior of the curve:
  
  The outside / outer region of the curve referred to as the exterior of the curve. In the above figure, point $$B$$ lies on the exterior of the curve.
  
  3Boundary of the curve:
  
  The curve, which divides the interior and exterior part, is called a boundary of the curve. In the above figure, point $$C$$ lies on the boundary of the curve.
  
  Important!
  The interior and boundary of the curve together are called "the region" of the curves.
explanation: The provided text extract is a theoretical explanation about different types of curves, including simple, non-simple, open, and closed curves. It also describes the parts of a closed curve, such as the interior, exterior, and boundary. The text does not contain any specific math question or answer.
distilabel_metadata.content: Evaluate the user given text extract and determine if it contains a math question and optionally and answer to this question.
  
  Output rules:
  
  1. Briefly describe the document and mention if it contains a question or a question and answer.
  2. Finalize the output with: Label: no-question,question,question-and-answer,multiple-question,multiple-question-and-answer
