**Problem Statement:**

Several departments around campus have wireless access points, but problems arise if two wireless access points within 200 feet of each other are operating on the same frequency. Suppose the departments with wireless access points are situated as follows:

| Department   | Is within 200 feet of departments:               |
|--------------|--------------------------------------------------|
| Math         | Physics, Psychology, Chemistry, Sociology       |
| Sociology    | History, English, Economics, Math, Chemistry, Psychology |
| Physics      | Math, Chemistry                                  |
| Psychology   | Math, Chemistry, Sociology, Economics            |
| History      | Sociology, English                               |
| English      | Economics, Sociology, History                    |
| Economics    | English, Sociology, Psychology                   |
| Chemistry    | Math, Psychology, Sociology, Physics             |

**Question:**

a. Draw an undirected graph that represents the table above.

**Explanation for Drawing the Graph:**

- Each department is represented as a vertex (node).
- An edge is drawn between two vertices if the departments are within 200 feet of each other, based on the table provided.
- The graph is undirected, meaning the relationship is mutual; if Department A is within 200 feet of Department B, then Department B is also within 200 feet of Department A.
