Final answer:
The given statement discusses the predictability of natural objects, stating that the average pattern of a large sample is predictable, but specific individual objects cannot be predicted.
Step-by-step explanation:
The given statement is discussing the predictability of natural objects, such as roses, sunflowers, and elephant tusks. It states that the average pattern of a large sample of these natural objects is predictable, but it's impossible to be sure about the outcome of any individual object.
This means that while we can make predictions about the general behavior or characteristics of a large group of these objects, we cannot accurately predict the specific details or properties of any single object.
Therefore, the correct answer to the question is A. The unpredictability of individual natural objects.
