The correct answer is "The rules and codes it created were too complex".

Explanation:

The National Recovery Administration (NRA) was a national agency established in 1933 by U.S. president Franklin D. Roosevelt with the main goal of uniting different sectors of society by using codes of fair competition. The idea was to reduce destructive competition among industry, labor, and government by setting and following certain rules and codes. However, the NRA was unsuccessful because the rules and codes created were too complex and difficult to follow.

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.
