What is this Matrix question asking me to do?

In summary, a Matrix question is a structured format used to gather information and opinions from respondents. It presents a series of questions or statements and asks for ratings or rankings. Respondents can use a scale to indicate their level of agreement or preference, and can also provide additional comments or explanations. This type of question can collect both quantitative and qualitative data and can be customized according to specific needs. However, there may be limitations such as time-consuming and may not be suitable for all types of surveys. Additionally, they may not be suitable for mobile or small-screen devices.
