A.I. Explanation:

Option 1: "We should have an advance action plan in hand to react to a situation."

Explanation: This option suggests having a reactive approach, which contradicts the text's emphasis on being proactive and creating values. The text advocates for understanding and preventing violations rather than merely reacting to them.

Option 2: "We should judge the seriousness of the violation of human values and stand by the oppressed."

Explanation: While this option mentions standing by the oppressed, it focuses on judgment rather than proactive measures. The text encourages understanding the greater good and creating systems to prevent violations, rather than just assessing their seriousness.

Option 3: "We should understand the greater good and objectively create a system to preempt violations."

Explanation: This option aligns perfectly with the text's main idea, which emphasizes the need for understanding basic human values and being proactive. It reflects the author's call to create a system that prevents violations, thus addressing the 'big scars' like the Holocaust.

Option 4: "We should not be mute spectators and confront the perpetrators of heinous crimes."

Explanation: Although this option encourages action against perpetrators, it still implies a reactive stance. The text advocates for a deeper understanding and proactive measures to prevent violations, rather than just confronting them after they occur.
