Currently, this code is returning None responses due to failing in the answer validation process.

from edsl.questions import QuestionList

question_text = "How would you address the legal and ethical implications of  extraterrestiral colonization?"
q = QuestionList(
    question_text=f"""A person is desining a survey.
                 They are asking the following question: {question_text}

                 """,
    question_name="question_options",
)
out = q.run()
