The response element

Direct responses are a way to bypass C-Phrase completely on certain user questions. Responses apply immediately to user questions before pre-processing. So for example, this might help users understand that governors are not covered in the geography database.

<response from="governor" to="We do not have information on the governors of states."/>

The definition of response is:

<!ATTLIST response
          from CDATA #REQUIRED
          to CDATA #REQUIRED
          alive CDATA #IMPLIED
          description CDATA #IMPLIED>

from is the pattern that, if matched anywhere in the input, leads to the activation of the response.

to is the exact response that is given to the user question.
