Correct choices:
- The plant was exposed to more intense light.
- The plant absorbed more carbon dioxide.
Why: In the photosynthesis equation CO2 and light are reactants; increasing either (up to a saturation point) increases the rate of glucose production. Less light or less CO2 would decrease glucose production. Oxygen is a product of photosynthesis, not a reactant, so changes in O2 uptake do not drive increased glucose production.
