Social Network A group of friends is represented by the graph at the left. An edge connecting two names means that the two friends have spoken to each Other in the last week.

- Have John and Stacy talked to each other in the last week?
- How many of the friends in this group has Steve talked to in the last week?
- Among this group of friends, who has talked to the most people in the last week?
- Why would it make sense for this graph to contain a loop?

To determine

**(a)**
