Which statement most accurately describes the roles of the president and congress in creating new federal laws?

(C)congress has the power to propose laws, but the president must approve them in most cases.

Explanation:

The U.S. Congress has two legislative bodies: the U.S. Senate and the U.S. House of Representatives. Any person elected to either body is allowed to propose a new law.

Once both bodies accept a bill, they present it to the president, who then considers the bill and is able to approve it and sign it into law or veto it.  

If the president decides to veto a bill, the Congress can choose to override that veto and the bill converts into a law. But, if the president pocket vetoes the bill after Congress has adjourned, the veto cannot be revoked.

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.
