The FBI also spied upon and collected information on Puerto Rican independence leader Pedro Albizu Campos and his Nationalist political party in the 1930s. Abizu Campos was convicted three times in connection with deadly attacks on US government officials: in 1937 (Conspiracy to overthrow the government of the United States), in 1950 (attempted murder), and in 1954 (after an armed assault on the US House of Representatives while in session; although not present, Abizu Campos was considered the mastermind). The FBI operation was covert and did not become known until U.S. Congressman Luis Gutierrez had it made public via the Freedom of Information Act in the 1980s.
When was the Abizu Campos operation made public?
****
The answer: 1980s


The problem: Answer a question about this article:
As with personae in general, a character's face or heel alignment may change with time, or remain constant over its lifetime (the most famous example of the latter is Ricky Steamboat, a WWE Hall of Famer who remained a babyface throughout his entire career). Sometimes a character's heel turn will become so popular that eventually the audience response will alter the character's heel-face cycle to the point where the heel persona will, in practice, become a face persona, and what was previously the face persona, will turn into the heel persona, such as when Dwayne Johnson first began using "The Rock" persona as a heel character, as opposed to his original "Rocky Maivia" babyface persona. Another legendary example is Stone Cold Steve Austin, who was originally booked as a heel, with such mannerisms as drinking on the job, using profanity, breaking company property, and even breaking into people's private homes. However, much to WWF's surprise, the fans enjoyed Austin's antics so much that he became one of the greatest antiheroes in the history of the business. He, along with the stable of D-Generation X, is generally credited with ushering in the Attitude Era of WWF programming.
What did Stone Cold Steve Austin start as? 
****
The answer: heel


The problem: Answer a question about this article:
Feynman had a great deal of success teaching Carl, using, for example, discussions about ants and Martians as a device for gaining perspective on problems and issues. He was surprised to learn that the same teaching devices were not useful with Michelle. Mathematics was a common interest for father and son; they both entered the computer field as consultants and were involved in advancing a new method of using multiple computers to solve complex problems—later known as parallel computing. The Jet Propulsion Laboratory retained Feynman as a computational consultant during critical missions. One co-worker characterized Feynman as akin to Don Quixote at his desk, rather than at a computer workstation, ready to do battle with the windmills.
What type of computing did Feynman and his son help develop?
****
The answer:
parallel computing
