Problem: Kathmandu:

The neighbourhood of Thamel is Kathmandu's primary "traveller's ghetto", packed with guest houses, restaurants, shops, and bookstores, catering to tourists. Another neighbourhood of growing popularity is Jhamel, a name for Jhamsikhel coined to rhyme with Thamel. Jhochhen Tol, also known as Freak Street, is Kathmandu's original traveler's haunt, made popular by the hippies of the 1960s and 1970s; it remains a popular alternative to Thamel. Asan is a bazaar and ceremonial square on the old trade route to Tibet, and provides a fine example of a traditional neighbourhood.

What tourists first brought attention to Jhocchen Tol?
---
A: hippies

Problem: Gramophone record:

The playing time of a phonograph record depended on the turntable speed and the groove spacing. At the beginning of the 20th century, the early discs played for two minutes, the same as early cylinder records. The 12-inch disc, introduced by Victor in 1903, increased the playing time to three and a half minutes. Because a 10-inch 78 rpm record could hold about three minutes of sound per side and the 10-inch size was the standard size for popular music, almost all popular recordings were limited to around three minutes in length. For example, when King Oliver's Creole Jazz Band, including Louis Armstrong on his first recordings, recorded 13 sides at Gennett Records in Richmond, Indiana, in 1923, one side was 2:09 and four sides were 2:522:59.

What factors would effect playing time of a phonograph?
---
A: turntable speed and the groove spacing

Problem: Emotion:

Sociological attention to emotion has varied over time. Emile Durkheim (1915/1965) wrote about the collective effervescence or emotional energy that was experienced by members of totemic rituals in Australian aborigine society. He explained how the heightened state of emotional energy achieved during totemic rituals transported individuals above themselves giving them the sense that they were in the presence of a higher power, a force, that was embedded in the sacred objects that were worshipped. These feelings of exaltation, he argued, ultimately lead people to believe that there were forces that governed sacred objects.

What society was studied to describe the notion of collective effervescence?
---
A:
Australian aborigine society
