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

Q: 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.

A: two tones are played simultaneously

Q: Why might someone distract a person in pain?, Context: Pain is the most common reason for physician consultation in most developed countries. It is a major symptom in many medical conditions, and can interfere with a person's quality of life and general functioning. Psychological factors such as social support, hypnotic suggestion, excitement, or distraction can significantly affect pain's intensity or unpleasantness. In some arguments put forth in physician-assisted suicide or euthanasia debates, pain has been used as an argument to permit terminally ill patients to end their lives.

A: affect pain's intensity or unpleasantness

Q: When did Tito create his own rule?, Context: Tito was the chief architect of the second Yugoslavia, a socialist federation that lasted from 1943 to 199192. Despite being one of the founders of Cominform, soon he became the first Cominform member to defy Soviet hegemony and the only one to manage to leave Cominform and begin with its own socialist program. Tito was a backer of independent roads to socialism (sometimes referred to as "national communism"). In 1951 he implemented a self-management system that differentiated Yugoslavia from other socialist countries. A turn towards a model of market socialism brought economic expansion in the 1950s and 1960s and a decline during the 1970s. His internal policies included the suppression of nationalist sentiment and the promotion of the "brotherhood and unity" of the six Yugoslav nations. After Tito's death in 1980, tensions between the Yugoslav republics emerged and in 1991 the country disintegrated and went into a series of wars and unrest that lasted the rest of the decade, and which continue to impact most of the former Yugoslav republics. He remains a very controversial figure in the Balkans.

A:
1951
