Sentence: Simultaneously with these conflicts, bison, a keystone species and the primary protein source that Native people had survived on for centuries were being destroyed. Some estimates say there were over 13 million bison in Montana in 1870. In 1875, General Philip Sheridan pleaded to a joint session of Congress to authorize the slaughtering of herds in order to deprive the Indians of their source of food. By 1884, commercial hunting had brought bison to the verge of extinction; only about 325 bison remained in the entire United States. 
Question: About how many bison were in Montana in 1870?

Ex Output:
over 13 million

Sentence: 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. 
Question: How many public performances did Chopin do where he made his debut after completing his education?

Ex Output:
two
