/**
* This [`Ability`](https://serenity-js.org/api/core/class/Ability/) enables an [`Actor`](https://serenity-js.org/api/core/class/Actor/) to resolve the value of a given [`Answerable`](https://serenity-js.org/api/core/#Answerable).
*
* `AnswerQuestions` is used internally by [`Actor.answer`](https://serenity-js.org/api/core/class/Actor/#answer), and it is unlikely you'll ever need to use it directly in your code.
* That is, unless you're building a custom Serenity/JS extension and want to override the default behaviour of the framework,
* in which case you should check out the [Contributor's Guide](https://serenity-js.org/community/contributing/).
