Back in Warsaw that year, Chopin heard Niccolò Paganini play the violin, and composed a set of variations, Souvenir de Paganini. It may have been this experience which encouraged him to commence writing his first Études, (1829–32), exploring the capacities of his own instrument. On 11 August, three weeks after completing his studies at the Warsaw Conservatory, he made his debut in Vienna. He gave two piano concerts and received many favourable reviews—in addition to some commenting (in Chopin's own words) that he was "too delicate for those accustomed to the piano-bashing of local artists". In one of these concerts, he premiered his Variations on Là ci darem la mano, Op. 2 (variations on an aria from Mozart's opera Don Giovanni) for piano and orchestra. He returned to Warsaw in September 1829, where he premiered his Piano Concerto No. 2 in F minor, Op. 21 on 17 March 1830.
How many weeks after completing school was it before Chopin made his public debut?
****
The answer: three

As the election approached, other prominent citizens and politicians from both parties urged Eisenhower to run for president. In January 1948, after learning of plans in New Hampshire to elect delegates supporting him for the forthcoming Republican National Convention, Eisenhower stated through the Army that he was "not available for and could not accept nomination to high political office"; "life-long professional soldiers", he wrote, "in the absence of some obvious and overriding reason, [should] abstain from seeking high political office". Eisenhower maintained no political party affiliation during this time. Many believed he was forgoing his only opportunity to be president; Republican Thomas E. Dewey was considered the other probable winner, would presumably serve two terms, and Eisenhower, at age 66 in 1956, would then be too old.
How old would Eisenhower be in 1956?
****
The answer: 66

On St. George's Night (Estonian: Jüriöö ülestõus) 23 April 1343, the indigenous Estonian population in the Duchy of Estonia, the Bishopric of Ösel-Wiek and the insular territories of the State of the Teutonic Order tried to rid themselves of the Danish and German rulers and landlords, who had conquered the country in the 13th century during the Livonian crusade, and to eradicate the non-indigenous Christian religion. After initial success the revolt was ended by the invasion of the Teutonic Order. In 1346 the Duchy of Estonia was sold for 19,000 Köln marks to the Teutonic Order by the King of Denmark. The shift of sovereignty from Denmark to the State of the Teutonic Order took place on 1 November 1346.
What date did sovereignty shift from the state of Denmark?
