@jennifer.achan In Side by side, column is the questions that you want to ask (multiple question, that’s why it’s called side by side), each question have different set of answer, so you can click on column option to add answer.
 

If you only have 1 question to ask across multiple statement, then matrix table is the correct question type that suite you.
Hope this helps
