我咁睇啦
Logically

題目問show how rate of photosynthesis is only dependent on light intensity
-> 佢暗示佢覺得light intensity 係呢個裝置下唔係only variable
-> 所以先叫你show how to modify

至於bicarbonate sol
-> yes same concentration of sol used
-> it can "speed up the rate"
-> 但你地咁做就assume呢個裝置下light intensity is the only variable
-> which is not what q asked

Lm 等人答

其實最好cover with black curtain + bicarbonate
-> show the bulb light only variable
-> rate of photosynthesis enhanced to become more observable

唔係suggest one modification咩
:^(

所以前者，
Black curtain 先係回應緊題目

後者bicarbonate 係「已經」assumed bulb light is the only variable which we don't know

呢題寫左唔用light bulb 因為會有熱

但佢題目show how light intensity is the only variable

咁你答左咩？
你答案未見過
