 Options Question
 ^^^^^^^^^^^^^^^^
 
 The options question contains a closed list of :ref:`answers<answer>` where users can pick one. Answers can have some follow-up questions that are only presented to the user when they pick the answer. So the options question can be used for questionnaire branching.

 List Question
 ^^^^^^^^^^^^^
 
 The list question is used when there are multiple answers and we want to ask more details about those. For example, we can ask about different datasets that will be produced -- users will have multiple datasets but we want to ask the same questions for each of those. For that, we configure the **item template**, which defines the questions for each item.

 We can define question tags on the knowledge model and then assign them to different :ref:`questions<question>`. This can be used to group together questions on the same topic or for the same purpose.
 
-When researchers create a new project from the knowledge model, they can only choose the question groups they are interested in for their research. So we can use this to create a very rich knowledge model but researchers will be able to use only the parts relevant to them.
