“We become builders by building and we become just be doing what is just” In the light of this statement what can not be asserted?

The correct option is: Skills are acquired by performing relevant activity.

Let us break down the logical reasoning step-by-step to understand why this option represents what cannot be asserted from the statement: "We become builders by building and we become just by doing what is just."

1. Analyzing the Core Statement:
The statement is a classic philosophical assertion (often attributed to Aristotle's virtue ethics) that draws an analogy between learning a craft/skill (like building) and developing a moral virtue (like justice). The primary focus of the statement is to explain the mechanism of moral habituation—how human beings develop ethical virtues through repeated practice.

2. The Role of the Analogy:
The mention of "builders by building" serves strictly as an illustrative analogy to make the concept of moral development easier to understand. The statement is not attempting to define or assert a universal theory about how all practical, mechanical, or cognitive skills are acquired in general.

3. Why it Cannot Be Asserted:
Because the statement's true subject and objective are about ethical habituation ("becoming just"), we cannot use it to assert a generalized claim about skill acquisition. Extrapolating a universal rule that "skills are acquired by performing relevant activity" goes beyond the intended ethical scope of the statement. Therefore, in the context of what the statement is actually arguing, this general assertion about skill acquisition cannot be directly asserted.
