PROBLEM: Passage: Everton were founder members of the Premier League in 1992, but struggled to find the right manager. Howard Kendall had returned in 1990 but could not repeat his previous success, while his successor, Mike Walker, was statistically the least successful Everton manager to date. When former Everton player Joe Royle took over in 1994 the club's form started to improve; his first game in charge was a 2–0 victory over derby rivals Liverpool. Royle dragged Everton clear of relegation, leading the club to the FA Cup for the fifth time in its history, defeating Manchester United 1–0 in the final.

SOLUTION: Who was Everton's first manager after founding the Premier League?

PROBLEM: Passage: When anti-German demonstrations erupted in Prague, Czechoslovakia, the Comintern ordered the Czech Communist Party to employ all of its strength to paralyze "chauvinist elements." Moscow soon forced the Communist Parties of France and Great Britain to adopt an anti-war position. On 7 September, Stalin called Georgi Dimitrov,[clarification needed] and the latter sketched a new Comintern line on the war. The new line—which stated that the war was unjust and imperialist—was approved by the secretariat of the Communist International on 9 September. Thus, the various western Communist parties now had to oppose the war, and to vote against war credits. Although the French Communists had unanimously voted in Parliament for war credits on 2 September and on 19 September declared their "unshakeable will" to defend the country, on 27 September the Comintern formally instructed the party to condemn the war as imperialist. By 1 October the French Communists advocated listening to German peace proposals, and Communist leader Maurice Thorez deserted from the French Army on 4 October and fled to Russia. Other Communists also deserted from the army.

SOLUTION: The eastern communists new rhetoric was that the war was?
