This paper prints marks IN FRONT of the question number on every line (e.g. "5 1. What are the elements…", "4 16. All 29 questions are answered in full.
Question text not reproduced: the examination questions are © Engineers and Geoscientists BC. Open the official past paper (linked at the top of this page) to read the question, then follow the worked solution below.
(1) Socioeconomic level and lifestyle — higher-income communities and areas with higher packaged/consumer-goods consumption typically generate more waste per capita. (2) Geographic location and season — climate affects yard-waste generation (longer growing season, more leaf/grass waste) and can affect packaging/food-waste habits. (3) Extent of local waste reduction, reuse and recycling programs — a community with well-established, mandatory diversion programs shows a lower disposed (residual) generation rate even where total waste GENERATED is similar, because more material is captured before disposal. (Other accepted factors: urban vs. rural setting, degree of commercial/industrial activity mixed into the municipal stream, and local regulation/public attitude.)
