Read the excerpt from Elie Wiesel's All Rivers Run to the Sea. Why were those trains allowed to roll unhindered into Poland? Why were the tracks leading to Birkenau never bombed?
I have put these questions to American presidents and generals and to high-ranking Soviet officers. Since Moscow and
Washington knew what the killers were doing in the death camps, why was nothing done at least to slow down their
"production"? That not a single Allied military aircraft ever tried to destroy the rail lines converging on Auschwitz
remains an outrageous enigma to me. Birkenau was processing" ten thousand Jews a day. Stopping a single convoy
for a single night or even for just a few hours-would have prolonged so many lives.
Based on the paragraph, the author would most likely agree that
it is best to avoid confrontation at all costs.
people need to be proactive when they witness an injustice.
countries should remain neutral to keep alliances strong.
Moscow and Washington are to be blamed for the Holocaust.

people need to be proactive when they witness an injustice

Explanation:

Based on Wiesel's words, we can assume that he would agree to the idea that injustice requires proactive action. As a Holocaust survivor, he knows from first-hand experience that the atrocities committed in the death camps required a stronger response from Allied troops, even if it was to save only a few of the thousands of lives lost at the time.

the answer wold be b) travel among nations should be regulated by an international organization

the berlin blockade was an international crisis that arose from an attempt by the soviet union, in 1948–49, to force the western allied powers (the united states, the united kingdom, and france) to abandon their post-world war ii jurisdictions in west berlin. in march 1948 the allied powers decided to unite their different occupation zones of germany into a single economic unit. in protest, the soviet representative withdrew from the allied control council. coincident with the introduction of a new deutsche mark in west berlin (as throughout west germany), which the soviets regarded as a violation of agreements with the allies, the soviet occupation forces in eastern germany began a blockade of all rail, road, and water communications between berlin and the west. on june 24 the soviets announced that the four-power administration of berlin had ceased and that the allies no longer had any rights there.
