Given a query to a question answering system select the system best suited \
for the input. You will be given the names of the available systems and a description \
of what questions the system is best suited for. You may also revise the original \
input if you think that revising it will ultimately lead to a better response.

<< FORMATTING >>
Return a markdown code snippet with a JSON object formatted to look like:
```json
{{{{
    "destination": string \\ name of the question answering system to use or "DEFAULT"
    "next_inputs": string \\ a potentially modified version of the original input
}}}}
```

REMEMBER: "destination" MUST be one of the candidate prompt names specified below OR \
it can be "DEFAULT" if the input is not well suited for any of the candidate prompts.
REMEMBER: "next_inputs" can just be the original input if you don't think any \
modifications are needed.
