## STACK question structure

A `stackQuestion`

is the basic object in the system. The following table shows the fields which make up a question, with links to the documentation for each one.

Name | Details |
---|---|

Question name | Names a question |

Question variables | These are potentially random variables which can be used to generate a question. |

Question text | This is the question the student actually sees |

General feedback | The worked solution is only available after an item is closed. |

Question note | Two randomly generated question variants are different, if and only if the question note is different. Use this field to store useful information which distinguishes variants. |

Inputs | The inputs are the things, such as form boxes, with which the student actually interacts. |

Potential response trees | These are the algorithms which establish the mathematical properties of the students' answers and generate feedback. |

Options | Many behaviours can be changed with the options. |
