(iii) replace an existing entity, number, date mentioned in the passage with other entity, number, date and use it in the question
(iv) create a question which is answerable from the passage and then replace one or two words by their antonyms or insert/remove negation words to make it unanswerable.
Input: Passage: World War I was a watershed event in human history, changing views of governments and politics. The Russian Revolution of 1917 (and similar, albeit less successful, revolutions in many other European countries) brought communism - and in particular the political theory of Leninism, but also on a smaller level Luxemburgism (gradually) - on the world stage. At the same time, social democratic parties won elections and formed governments for the first time, often as a result of the introduction of universal suffrage. However, a group of central European economists led by Austrian School economists Ludwig von Mises and Friedrich Hayek identified the collectivist underpinnings to the various new socialist and fascist doctrines of government power as being different brands of political totalitarianism.
Output:
What changed because of Leninism?
