Sample Question
In 1928, Sir Alexander Fleming was studying Staphylococcus bacteria growing in culture dishes. He noticed that a mold called Penicillium was also growing in some of the dishes. As shown in the illustration below, Petri dish A represents a dish containing only Staphylococcus bacteria. In dishes containing thePenicillium mold, represented by Petri dish B below, Fleming noticed that a clear area existed around the mold because all the bacteria in this area had died. In the culture dishes without the mold, no clear areas were present. Fleming suggested that the mold was producing a chemical that killed the bacteria. He decided to isolate this substance and test it to see if it would kill bacteria. Fleming grew some Penicillium mold in a nutrient broth. After the mold grew in the broth, he removed all the mold from the broth and added the broth to a culture of bacteria. All the bacteria died.Which of the following statements is a reasonable expression of Fleming's hypothesis?

Nutrient broth kills bacteria.

There are clear areas around the Penicillium mold where Staphylococcus doesn't grow.

Mold kills bacteria.

Penicillium mold produces a substance that kills Staphylococcus.

Without mold in the culture dish, there were no clear areas in the bacteria.
