An environmental psychologist investigated the relationship between ecological literacy (understanding of terms related to sustainability) and household energy-conservation behaviors. She used an opportunity sample of 50 local homeowners.
Each participant completed an ecological literacy questionnaire. This questionnaire involved matching 10 key environmental terms to their dictionary definitions and answering 10 closed questions to assess their understanding of the meaning of specific sustainability concepts. The participants' energy-conservation behaviors were then measured using a home smart-meter activity log.
Write a closed question that could have been used in the ecological literacy questionnaire to assess a participant's understanding of the meaning of a specific sustainability term.
