The correct Answer is:
To solve the question regarding the formation of big holes in Swiss cheese, follow these steps: ### Step-by-Step Solution: 1. **Identify the Key Component**: The question is about the formation of big holes in Swiss cheese. We need to determine what causes these holes. 2. **Understand the Role of Bacteria**: Swiss cheese is produced using a specific bacterium known as *Propionibacterium shermanii*. This bacterium plays a crucial role in the cheese-making process. 3. **Process of Cheese Production**: During the fermentation process, *Propionibacterium shermanii* consumes lactic acid. This is an important step in the production of Swiss cheese. 4. **Gas Production**: As the bacterium consumes lactic acid, it releases carbon dioxide gas as a byproduct. This is a key point because the gas produced is responsible for the holes. 5. **Formation of Holes**: The carbon dioxide gas forms bubbles in the cheese. These bubbles are what create the characteristic holes in Swiss cheese. 6. **Evaluate the Options**: Now we can evaluate the provided options: - (a) A machine - Incorrect, as machines do not create the holes. - (b) A bacterium that produces methane gas - Incorrect, as the relevant bacterium produces carbon dioxide, not methane. - (c) A bacterium producing a large amount of carbon dioxide - Correct, as this describes the action of *Propionibacterium shermanii*. - (d) A fungus that releases a lot of gases - Incorrect, as the holes are not formed by a fungus. 7. **Conclusion**: Based on the above analysis, the correct answer is (c) a bacterium producing a large amount of carbon dioxide. ### Final Answer: (c) a bacterium producing a large amount of carbon dioxide. ---
