To keep production going by not striking.

Explanation:

On December 15, 1941, a policy against striking in war industries had the absolute vote of the Executive Council of the American Federation of Labor. The attack against Pearl Harbor on December 7th caused the U.S. to declare war on Japan, and soon after on fascist Germany and Italy.  Some days following the attack, Roosevelt met with representatives of labor and industry looking for an agreement over a war labor policy preventing strikes that would affect production during the war.

the correct answer is d

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.
