Problem: Beginning as a self-help program in the mid-1960s, the Cotton Research and Promotion Program (CRPP) was organized by U.S. cotton producers in response to cotton's steady decline in market share. At that time, producers voted to set up a per-bale assessment system to fund the program, with built-in safeguards to protect their investments. With the passage of the Cotton Research and Promotion Act of 1966, the program joined forces and began battling synthetic competitors and re-establishing markets for cotton. Today, the success of this program has made cotton the best-selling fiber in the U.S. and one of the best-selling fibers in the world.[citation needed]
What law was passed in 1966 to aid cotton producers?
The answer is the following: Cotton Research and Promotion Act

Problem: During the American Civil War, American cotton exports slumped due to a Union blockade on Southern ports, and also because of a strategic decision by the Confederate government to cut exports, hoping to force Britain to recognize the Confederacy or enter the war. This prompted the main purchasers of cotton, Britain and France, to turn to Egyptian cotton. British and French traders invested heavily in cotton plantations. The Egyptian government of Viceroy Isma'il took out substantial loans from European bankers and stock exchanges. After the American Civil War ended in 1865, British and French traders abandoned Egyptian cotton and returned to cheap American exports,[citation needed] sending Egypt into a deficit spiral that led to the country declaring bankruptcy in 1876, a key factor behind Egypt's occupation by the British Empire in 1882.
What characteristic of American cotton attracted buyers after the end of the Civil war?
The answer is the following: cheap

Problem: In 1977, Elizabeth marked the Silver Jubilee of her accession. Parties and events took place throughout the Commonwealth, many coinciding with her associated national and Commonwealth tours. The celebrations re-affirmed the Queen's popularity, despite virtually coincident negative press coverage of Princess Margaret's separation from her husband. In 1978, the Queen endured a state visit to the United Kingdom by Romania's communist dictator, Nicolae Ceausescu, and his wife, Elena, though privately she thought they had "blood on their hands". The following year brought two blows: one was the unmasking of Anthony Blunt, former Surveyor of the Queen's Pictures, as a communist spy; the other was the assassination of her relative and in-law Lord Mountbatten by the Provisional Irish Republican Army.
When did Princess Margaret separate from her husband?
The answer is the following:
