# Single Choice Set (H5P.SingleChoiceSet)

Quick questions, one after another, each with one right answer of two to four; the learner moves on at the first click.

- In each item of `choices`, the first of `answers` is the right one; the set shuffles them when shown.
- Keep answers short: they are buttons.

## Example

```json
{
  "type": "H5P.SingleChoiceSet",
  "params": {
    "choices": [
      { "question": "Which sea does the Danube reach?", "answers": ["Black Sea", "North Sea", "Baltic Sea"] },
      { "question": "Which river flows through Paris?", "answers": ["Seine", "Loire", "Rhône"] }
    ]
  }
}
```

## Fields of H5P.SingleChoiceSet 1.11

The example is `type` and `params` alone, and `params` holds the fields below. A source also names its own `title`, `language`, `license` and `authors`, all four required: the build refuses a source that leaves out any of them. The author's name and the licence are the user's: ask for what they have not given. For a name they skip, write the one you know them by, or "Unknown"; for a licence they skip, `U`.
