QUES: Von Neumann founded the field of game theory as a mathematical discipline. Von Neumann proved his minimax theorem in 1928. This theorem establishes that in zero-sum games with perfect information (i.e. in which players know at each time all moves that have taken place so far), there exists a pair of strategies for both players that allows each to minimize his maximum losses, hence the name minimax. When examining every possible strategy, a player must consider all the possible responses of his adversary. The player then plays out the strategy that will result in the minimization of his maximum loss.

What must a player consider when determining every possible strategy?
What is the answer?
ANS: all the possible responses of his adversary.
QUES: The Spanish language is the second most spoken language in the United States. There are 45 million Hispanophones who speak Spanish as a first or second language in the United States, as well as six million Spanish language students. Together, this makes the United States of America the second largest Hispanophone country in the world after Mexico, and with the United States having more Spanish-speakers than Colombia and Spain (but fewer first language speakers). Spanish is the Romance language and the Indo-European language with the largest number of native speakers in the world. Roughly half of all American Spanish-speakers also speak English "very well," based on their self-assessment in the U.S. Census.

Half of all Spanish speakers also speak what very well?
What is the answer?

QUES: Tito's greatest strength, in the eyes of the western communists, had been in suppressing nationalist insurrections and maintaining unity throughout the country. It was Tito's call for unity, and related methods, that held together the people of Yugoslavia. This ability was put to a test several times during his reign, notably during the Croatian Spring (also referred as the Masovni pokret, maspok, meaning "Mass Movement") when the government suppressed both public demonstrations and dissenting opinions within the Communist Party. Despite this suppression, much of maspok's demands were later realized with the new constitution, heavily backed by Tito himself against opposition from the Serbian branch of the party.[citation needed] On 16 May 1974, the new Constitution was passed, and the aging Tito was named president for life, a status which he would enjoy for five years.

Who was named President for Life of Yugoslavia in 1974?
