b) the mixture needs more sugar, because yeast need a lot of energy before they can begin to produce alcohol.
c) the mixture needs more oxygen, because yeast need oxygen to break down sugar and get enough energy to produce alcohol
d) the mixture needs less oxygen, because yeast only produce alcohol in the absence of oxygen
