Questions: Phần bài tập 1. Cho các bộ khái niệm sau đây, hãy biểu diễn mối quan hệ giữa chúng bằng sơ đồ Euler (còn gọi là sơ đồ Venn) : a). Sinh viên, học sinh, thanh niên.

To represent the relationship between the concepts "sinh viên" (students), "học sinh" (pupils), and "thanh niên" (youth) using an Euler or Venn diagram, we need to understand the definitions and relationships between these terms.

1. Definitions:

   • Sinh viên: Typically refers to individuals who are attending a university or college. They are usually older than high school students.
   • Học sinh: Generally refers to students in primary and secondary education, including high school.
   • Thanh niên: Refers to young people, often defined as individuals in their teenage years up to their late twenties.

2. Relationships:

   • Sinh viên are a subset of thanh niên because university students are typically within the age range considered as youth.
   • Học sinh can also be a subset of thanh niên, especially those in high school, as they fall within the youth age range.
   • There is an overlap between sinh viên and học sinh in terms of age, but they are distinct categories based on the level of education.

3. Diagram Representation:

   • Draw a large circle labeled "Thanh niên" to represent all youth.
   • Inside this circle, draw two smaller circles: one labeled "Sinh viên" and another labeled "Học sinh".
   • The "Sinh viên" circle should be entirely within the "Thanh niên" circle.
   • The "Học sinh" circle should also be within the "Thanh niên" circle, but it can overlap with the "Sinh viên" circle to represent high school students who are also considered youth.

This Venn diagram visually represents the relationships and subsets among the three concepts.
