Problem: Eton College:

The long-standing claim that the present uniform was first worn as mourning for the death of George III is unfounded. "Eton dress" has undergone significant changes since its standardisation in the 19th century. Originally (along with a top-hat and walking-cane), Etonian dress was reserved for formal occasions, but boys wear it today for classes, which are referred to as "divisions", or "divs". As stated above, King's Scholars wear a black gown over the top of their tailcoats, and occasionally a surplice in Chapel. Members of the teaching staff (known as Beaks) are required to wear a form of school dress when teaching.

What are students known as at Eton?

Problem: On June 12, 1990, the Congress of People's Deputies adopted the Declaration of State Sovereignty. On June 12, 1991, Boris Yeltsin was elected the first President. On December 8, 1991, heads of Russia, Ukraine and Belarus signed the Belavezha Accords. The agreement declared dissolution of the USSR by its founder states (i.e. denunciation of 1922 Treaty on the Creation of the USSR) and established the CIS. On December 12, the agreement was ratified by the Russian Parliament, therefore Russian SFSR denounced the Treaty on the Creation of the USSR and de facto declared Russia's independence from the USSR.

Context and question: Acid house arose from Chicago artists' experiments with the squelchy Roland TB-303 bass synthesizer, and the style's origins on vinyl is generally cited as Phuture's "Acid Tracks" (1987). Phuture, a group founded by Nathan "DJ Pierre" Jones, Earl "Spanky" Smith Jr., and Herbert "Herb J" Jackson, is credited with having been the first to use the TB-303 in the house music context. The group's 12-minute "Acid Tracks" was recorded to tape and was played by DJ Ron Hardy at the Music Box, where Hardy was resident DJ. Hardy once played it four times over the course of an evening until the crowd responded favorably. The track also utilized a Roland TR-707 drum machine.
What type of drum machine did Hardy use?
