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.

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: Sara Keith, Penny Kelley, Veronica Brown, Gregory Hester, Michael Rojas, Thomas Lopez, Daniel Holmes, Amanda Gardner, Janet Harris, William Smith, Melissa Jenkins, Tiffany Barnett, Jerry Silva, Jeffrey Gibson, Desiree Kramer
- Fiendship connections: Sara Keith to Penny Kelley, Sara Keith to Desiree Kramer, Sara Keith to Veronica Brown, Sara Keith to Amanda Gardner, Sara Keith to Daniel Holmes, Veronica Brown to Amanda Gardner, Veronica Brown to Daniel Holmes, Gregory Hester to Michael Rojas, Gregory Hester to Jerry Silva, Gregory Hester to Jeffrey Gibson, Gregory Hester to Thomas Lopez, Gregory Hester to Tiffany Barnett, Gregory Hester to Janet Harris, Gregory Hester to Melissa Jenkins, Daniel Holmes to Amanda Gardner
Identify all connected components in this network. Note that for each connected component, you should only output one of its nodes.
