When naming inputs, Rails uses certain conventions that make it possible to submit parameters with non-scalar values such as arrays or hashes, which will also be accessible in `params`. You can read more about them in chapter [Understanding Parameter Naming Conventions](#understanding-parameter-naming-conventions) of this guide. For details on the precise usage of these helpers, please refer to the [API documentation](https://api.rubyonrails.org/classes/ActionView/Helpers/FormTagHelper.html).

As with `check_box`, the second parameter to [`radio_button`](https://api.rubyonrails.org/classes/ActionView/Helpers/FormBuilder.html#method-i-radio_button) is the value of the input. Because these two radio buttons share the same name (`age`), the user will only be able to select one of them, and `params[:age]` will contain either `"child"` or `"adult"`.
