Which statement about oxygen production is supported by the information?

• A. A 50x50 ft lawn area produces enough oxygen to support a family of 4 for one year
• B. A 50x50 ft lawn area produces enough oxygen to support a family of 2
• C. A 50x50 ft lawn area produces no oxygen
• D. A 50x50 ft lawn area produces enough oxygen to support a family of 6

Answer: (A)

The important idea is that plants generate oxygen through photosynthesis, and the amount of oxygen produced scales with the amount of green surface area actively photosynthesizing. A 50 by 50 foot lawn provides a sizable area of living green tissue, so the information available indicates it can produce a meaningful amount of oxygen over time. That is why the statement that this lawn could support a family of four for a year is the one supported by the data. The other options imply smaller or zero oxygen production, which isn’t aligned with the given information about this lawn’s capacity.
