Marcus coordinates a community-supported agriculture (CSA) scheme. He is considering transitioning the farm to a fully certified biodynamic and zero-waste cultivation model. This transition would guarantee higher-quality organic yields and offer educational weekend workshops, but it would require a 25% increase in the members' annual subscription fees.
To gather opinions on this transition from the members and their households, Marcus distributed a questionnaire containing a combination of open and closed questions. He relied on volunteer sampling by posting a request on the community noticeboard for members to complete the questionnaire.
Explain one strength and one weakness of Marcus using a questionnaire to collect opinions regarding the transition to the biodynamic model.
