Returns the first algorithm's prediction.
Original input query.
A list of algorithms' predictions.

:: DeveloperApi :: Engine developers should not use this directly. This is called by serving layer to combine multiple predicted results from multiple algorithms, and custom business logic before serving to the end user.
Query
List of predicted results
A single predicted result
