In this task, you are given a question and a context passage. You have to answer the question based on the given passage.

Input: Consider Input: How can you reduce the jnd?, Context: The just-noticeable difference (jnd) (the threshold at which a change is perceived) depends on the tone's frequency content. Below 500 Hz, the jnd is about 3 Hz for sine waves, and 1 Hz for complex tones; above 1000 Hz, the jnd for sine waves is about 0.6% (about 10 cents). The jnd is typically tested by playing two tones in quick succession with the listener asked if there was a difference in their pitches. The jnd becomes smaller if the two tones are played simultaneously as the listener is then able to discern beat frequencies. The total number of perceptible pitch steps in the range of human hearing is about 1,400; the total number of notes in the equal-tempered scale, from 16 to 16,000 Hz, is 120.

Output: two tones are played simultaneously


Input: Consider Input: Which ship is older, the Tripoli, or the Enterprise?, Context: With the deactivation of USS Enterprise in December 2012, the U.S. fleet comprises 10 supercarriers. The House Armed Services Seapower subcommittee on 24 July 2007, recommended seven or maybe eight new carriers (one every four years). However, the debate has deepened over budgeting for the $12–14.5 billion (plus $12 billion for development and research) for the 100,000 ton Gerald R. Ford-class carrier (estimated service 2016) compared to the smaller $2 billion 45,000 ton America-class amphibious assault ships, which are able to deploy squadrons of F-35Bs. The first of this class, USS America, is now in active service with another, USS Tripoli, under construction and 9 more are planned.

Output: Enterprise


Input: Consider Input: what was the second to last alternative name mentioned?, Context: A Spanish expedition was sent from Buenos Aires, organized by the Spanish governor of that city, Bruno Mauricio de Zabala. On 22 January 1724, the Spanish forced the Portuguese to abandon the location and started populating the city, initially with six families moving in from Buenos Aires and soon thereafter by families arriving from the Canary Islands who were called by the locals "guanches", "guanchos" or "canarios". There was also one significant early Italian resident by the name of Jorge Burgues.


Output: guanchos
