Part 1: The drawing below shows a Hasse diagram for a partial order on the set: {A, B, C, D, E, F, G, H, I, J} Figure 1: A Hasse diagrem shous 10 vertices and 8 adges. The vertices, represented by dots, are as follows: verter J is upward of vertez H; verter H is upward of vertez I; vertez B is inclined upward to the left of verter A; vertez C is upward of vertez B; verter D is inclined upuard to the right of vertez C; vertez E is inclined upward to the left of vertez F; verter G is inclined upwerd to the right of verter E. The edges, represented by line segments between the vertices are es follows: 3 verticel edges connect the following vertices: B and C, H and I, and H and J; 5 inclined edges connect the following vertices: A and B, C and D. D and E, E end F, and E end G. Determine the properties of the Hasse diagram based on the following questions: What are the minimal elements of the partial order?

Question
**Part 1: The drawing below shows a Hasse diagram for a partial order on the set: {A, B, C, D, E, F, G, H, I, J}**

**Figure 1 Explanation:**  
The Hasse diagram illustrates 10 vertices and 8 edges. The vertices are represented by dots and can be described as follows:
- Vertex J is directly above vertex H.
- Vertex H is directly above vertex B.
- Vertex B is directly above vertex A.
- Vertex G is directly above vertex C.
- Vertex C is directly above vertex B.
- Vertex D is directly above vertex A.
- Vertex E is directly above vertex D.
- Vertex F is directly above vertex E.

These vertices are connected by line segments that represent the edges of the diagram. The following connections can be observed:
- Vertices B and C are connected.
- Vertices H and J are connected.
- Vertices A and B are connected.
- Vertices D and C are connected.
- Vertices E and D are connected.
- Vertices F and E are connected.
- There is no direct connection between G and other vertices, but G is positioned above C.

The Hasse diagram assists in identifying the hierarchical relationships among the elements of the set.

**Questions:**

1. What are the minimal elements of the partial order?  
2. What are the maximal elements of the partial order?  
3. Which of the following pairs are comparable?  
   - (A, D), (J, F), (B, E), (G, F), (D, B), (C, F), (H, I), (C, E)

In a Hasse diagram:
- Minimal elements are those that have no elements directly below them.
- Maximal elements are those that have no elements directly above them.
- Two elements are comparable if there is a direct path of edges between them, following the precedence direction.
