Problem: Please answer a question about the following article about Frederic Chopin:
Fryderyk may have had some piano instruction from his mother, but his first professional music tutor, from 1816 to 1821, was the Czech pianist Wojciech Zywny. His elder sister Ludwika also took lessons from Zywny, and occasionally played duets with her brother. It quickly became apparent that he was a child prodigy. By the age of seven Fryderyk had begun giving public concerts, and in 1817 he composed two polonaises, in G minor and B-flat major. His next work, a polonaise in A-flat major of 1821, dedicated to Zywny, is his earliest surviving musical manuscript.
During what years did Chopin receive instruction from Zywny?
A: 1816 to 1821

Problem: Please answer a question about the following article about Hunting:
New Zealand has a strong hunting culture. The islands making up New Zealand originally had no land mammals apart from bats. However, once Europeans arrived, game animals were introduced by acclimatisation societies to provide New Zealanders with sport and a hunting resource. Deer, pigs, goats, rabbits, hare, tahr and chamois all adapted well to the New Zealand terrain, and with no natural predators, their population exploded. Government agencies view the animals as pests due to their effects on the natural environment and on agricultural production, but hunters view them as a resource.
What were the the only land mammal in New Zealand?
A:
bats
