Hi. You did not inform the survey to which this question refers, which makes it impossible for it to be answered accurately. However, I will try to help you as best I can.
Generally speaking, in a survey, quantitative topics are those that have numbers. These are the statistical, mathematical topics that seek to present the research through numerical data. Qualitative topics, on the other hand, are those that present explanations about the complexity of the research data, or present the details that are important for the understanding of the research, without taking into account statistical, mathematical and measurable data.
In that case, to answer that question, you should read the entire article that features the research and identify those topics based on the description above.
