Direction: In the question below are given two statements followed by...
The above two statements mention the advantages of refrigeration.
The first conclusion follows as the information given in the statements above say that the purpose of refrigeration is to keep the food cold and fresh.
Thus we can conclude that cold temperatures keep the food fresh for a longer time.
Hence, conclusion (1) follows.
The second conclusion follows as it can be concluded from the given information that refrigerating the food will slow down the activity of the bacteria and hence will not allow them to spoil the food very soon.
Hence, the correct option is (E).
Direction: In the question below are given two statements followed by...
Statement I: The fundamental reason for having a refrigerator is to keep the food cold and thus retaining its freshness.
Statement II: The basic idea behind refrigeration is to slow down the activity of the bacteria present in food.
Conclusion 1: Cold temperatures help the food to stay fresh.
Conclusion 2: Bacteria will take a longer time to spoil the food on refrigeration.
Explanation:
To assess the validity of the conclusions, let's analyze the given statements one by one.
Statement I: The fundamental reason for having a refrigerator is to keep the food cold and thus retaining its freshness.
This statement clearly states that one of the main purposes of a refrigerator is to keep the food cold, which helps in maintaining its freshness. Therefore, Conclusion 1: Cold temperatures help the food to stay fresh can be drawn from this statement.
Statement II: The basic idea behind refrigeration is to slow down the activity of the bacteria present in food.
This statement explains the underlying principle of refrigeration, which is to slow down the activity of bacteria in food. By reducing the temperature, the growth and activity of bacteria are significantly reduced, which helps in preserving the food. However, this statement does not explicitly mention anything about the time it takes for bacteria to spoil the food.
Now, let's evaluate the conclusions based on the given statements:
Conclusion 1: Cold temperatures help the food to stay fresh.
This conclusion is directly supported by Statement I, which states that the purpose of a refrigerator is to keep the food cold and retain its freshness. Therefore, Conclusion 1 can be drawn from the given statements.
Conclusion 2: Bacteria will take a longer time to spoil the food on refrigeration.
Although Statement II mentions that refrigeration slows down the activity of bacteria, it does not provide any information about the specific time it takes for bacteria to spoil the food. Therefore, Conclusion 2 cannot be definitively drawn from the given statements.
Therefore, the correct answer is option E) Both Conclusion 1 and Conclusion 2 follow.
