Database table data with different set of values I am trying to create a database table for my project but I stuck in this type of data.

The purpose is the admin can add, modify or insert types of questions and choices

example:

Do you like pokemon?


Yes 
No


Pick the pokemons you like

[] charmander

[] pikachu

[] squirtle

[] bulbasaur

Pick your starting pokemon:


charmander
pikachu
squirtle
bulbasaur


Why pikachu is so cute?



Explanation here



Here is my table

Questions table 


  id  |  question   |  type


Choices table 


  id  |    choice   |  question_id


UserAnswers  table 


  id  |    choice_id  | question_id  |  answer  |   userid


my problem is where to put the explanation of the user since it would be a large set of text? I am still very new in database designing and don't know what to do with this type of scenario. Please any recommendation for a good way to design my table.
I think you're on the right track.

I presume questions.type (NB type might be a reserved word and cause problems) will have the check constraint check type in ('multiple_choice','free_text') or something similar.

Then all you would need to do is rename your proposed UserAnswers to UserMultipleChoiceAnswers and drop the column answer, 
and create another table, UserFreeTextAnswers with columns id, question_id, answer, user_id.
