Ms tay:
Hi, ms tay. Based on my judgement and some online searching, I think the answer should be carbon dioxide as there is less carbon dioxide given out than oxygen. Thus, there would soon be a lack of carbon dioxide. Besides, water could not be used up that quickly.xDiorama:

Vianne77:
I just want to clarify with all of you, is it true that there is more weightage on English and Chinese? My friends and their mummies say that English+Chinese=200%, Science is 50% and Maths is 50% as well...
Oh yes, I want to ask about question: 'Which set-up should he use as a control'

It is not true that the weighting for English and Mother Tongue is greater than Maths and Science. -
