You can use a text question type to get responses in a free text form. On a report you get respondents answers exactly as they have written. There is also a possibility to form a word cloud graph out of free text comments. It is easy to have a quick look about the main findings in the data using this word cloud graph.
Hint:
Do you know exactly which are going to be most typical 2 to 10 answers to your question? You might want to consider using Single Choice or Multiple Choice question type instead to have more possibilities when analyzing results.
