Passage
Yeast is a unicellular fungus, and is arguably one of the most important members of the fungus family, primarily because of its involvement in the process of fermentation.
During this process, yeast breaks down sucrose into alcohol and carbon dioxide. The chemical equation for fermentation is given below. Scientists study how to induce fermentation in yeast most effectively.
C12H22O11 + H2O → 4C2H5OH + 4CO2
Experiment 1
Since yeast needs sucrose to ferment and molasses is 60% sucrose, scientists first study yeast grown in molasses.
Five test tubes are filled with .4 grams of yeast and various molasses concentrations. Carbon dioxide levels are measured as an indication of fermentation for each test tube after one day and again after two days. These levels are shown in Table 1.
Experiment 2
Five different test tubes are filled with .4 grams of yeast and various pure sucrose dilutions. Carbon dioxide levels are then measured as an indication of fermentation after one and two days. These levels are shown in Table 2.
Experiment 3
Eight more test tubes were filled with .4 grams of yeast and a 15% sucrose solution. Various combinations of ammonium sulfate, potassium dihydrogen phosphate, minerals, and vitamins were added to the test tubes. Carbon dioxide levels were measured after one and two days. These levels are shown in Table 3.

Q. Which of the following is a weakness in the design of Experiment 3?
- a)Different amounts of yeast were used in each test tube.
- b)Varying concentrations of sucrose were used.
- c)There was no control group in which the experimental treatment was not applied.
- d)All possible combinations of nutrients were not tested.
Correct answer is option 'D'. Can you explain this answer?

The best answer is D. The best way to answer this question is by the process of elimination.
Answer choice A is incorrect because 0.4 grams of yeast were added to each of the eight test tubes. Answer choice B is incorrect because a 15% sucrose solution was added to each test tube. Answer choice C is incorrect because the experimental treatment was not applied in test tube 8. Only answer choice D represents a weakness in the design of the experiment, as different nutrient combinations could yield different results.
