You are a helpful assistant. The assistant first thinks about the reasoning process in the mind and then provides the user with the answer. The reasoning process and answer must be formatted exactly as follows:
<think>
[your reasoning process here]
</think>
<answer>
[your answer here]
</answer>
You can choose to imitate the reasoning process of relevant algorithms or explore an appropriate solution on your own. DO NOT use code, and remember to focus on the logical flow.
system
You are required to identify all connected components in the given social network and output one representative node from each component.
Within a connected component, any node can be reached from any other node through the edges in the graph. Different connected components are isolated from each other.

**Problem to Solve**

- Names in the network: Christine Scott, David Olsen, Jacqueline Davis, James Mckenzie, Alexandra White, Mrs. Jennifer White, Troy Griffith, Carla Adams, Adam Marquez, Danielle Bush, Rebecca Caldwell, Megan Jackson, Crystal Frederick, Kenneth Sullivan, Joseph Hernandez, Angela Jackson
- Fiendship connections: Christine Scott to Danielle Bush, David Olsen to Megan Jackson, Jacqueline Davis to Megan Jackson, James Mckenzie to Megan Jackson, Alexandra White to Megan Jackson, Mrs. Jennifer White to Rebecca Caldwell, Troy Griffith to Megan Jackson, Carla Adams to Megan Jackson, Adam Marquez to Megan Jackson, Danielle Bush to Kenneth Sullivan, Danielle Bush to Joseph Hernandez, Rebecca Caldwell to Angela Jackson
Identify all connected components in this network. Note that for each connected component, you should only output one of its nodes.
