You have a Conversational Language Understanding model. You export the model as a JSON file. The following is a sample of the file. What represents the Weather.Historic entity in the sample utterance?

"last year" would likely be a distinct temporal entity, possibly `Weather.Historic.Year` or a generic `DateTime` entity.

In a Conversational Language Understanding (CLU) model, entities are specific spans of text within an utterance that represent relevant information. Given the entity type `Weather.Historic`, "by month" typically indicates a temporal aspect or aggregation for historical weather data, making it a valid extraction for such an entity.

"amount of" is a quantifier phrase, not typically an entity value itself but part of a larger intent or a modifier for a measurement entity.

"average" is an aggregation function or a property, not a specific entity value for `Weather.Historic`.
