Model Answer
(B) Lifestyle improvements increase the total quantity of waste, and packaging changes make a larger proportion of that waste non-biodegradable.
Explanation
The passage directly states: "Improvements in our life-style have resulted in greater amounts of waste material generation… Changes in packaging have resulted in much of our waste becoming non-biodegradable." Option B combines both effects accurately. Options A, C, and D contradict or misrepresent the passage.
