Bruno's father really knows when to argue and when to be silent, the problem is that he only does this for his own benefit and regardless of how his argument or silence can harm, hurt and even confuse other people. It was arguing that Bruno's father was able to establish his authority over those he recognizes as weaker and it was his ability to remain silent that allowed Bruno's father to achieve increasingly successful positions in his profession.
However, these capabilities contributed to Bruno's confusion and curiosity about the prisoners. It was exactly this curiosity and confusion that made Bruno come to a terrible end.
For this reason, we could advise Bruno's father not to remain silent in the face of injustices against the most disadvantaged people. Furthermore, he should use his ability to argue against injustices and explain to his family the wrong and awful things that are happening.
The correct answer is A. The boy's epiphany in "Araby" reveals the futility of human pursuits.
At the end of the story, the boy has several disappointments. His uncle is late, the bazaar is nearly closed by the time he gets there, and the only objects he finds are boring. All of his expectations have failed to live up to reality. The boy realizes that his relationship with Mangan's sister will end up the same -- better in his imagination than in reality.
In this way, the story says that life itself is disappointing and fails to live up to our imaginations. Answer A, that human pursuits are futile (or pointless), best encompasses the boy's epiphany.
