This question has 2 parts. The drawing below shows a Hasse diagram for a partial order on the set: H E JO B F {А, В, С, D, E, F, G, H, І, J} Figure 1: A Hasse diagram shows 10 vertices and 8 edges. The vertices, represented by dots, are as follows: verter J; vertices H and I are aligned vertically to the right of verter J; vertices A, B, C, D, and E form a closed loop, which is to the right of vertices H and I; verter G is inclined upward to the right of verter E; and verter F is inclined downward to the right of verter E. The edges, represented by line segments, between the vertices are as follows: verter J is connected to no verter; a vertical edge connects vertices H and I; a vertical edge connects vertices B and C; and 6 inclined edges connect the following vertices, A and B, C and D, D and E, A and E, E and G, and E and F. Part 1: Determine the properties of the Hasse diagram based on the following questions: (a) What are the minimal elements of the partial order? (b) What are the maximal elements of the partial order? (c) Which of the following pairs are comparable? (А, D), (J, F), (В, Е), (G, F), (D, B), (С, F), (Н, I), (С, E) D.

Figure 1: A Hasse diagram shows 10 vertices and 8 edges. The vertices, represented by dots, are
as follows: verter J; vertices H and I are aligned vertically to the right of verter J; vertices A, B, C, D,
and E form a closed loop, which is to the right of vertices H and I; verter G is inclined upward to the
right of verter E; and verter F is inclined downward to the right of verter E. The edges, represented
by line segments, between the vertices are as follows: verter J is connected to no verter; a vertical edge
connects vertices H and I; a vertical edge connects vertices B and C; and 6 inclined edges connect the
following vertices, A and B, C and D, D and E, A and E, E and G, and E and F.
Part 1: Determine the properties of the Hasse diagram based on the following questions:
(a) What are the minimal elements of the partial order?
