Later, the 3rd dynasty of Ur under Ur-Nammu and Shulgi, whose power extended as far as southern Assyria, was the last great "Sumerian renaissance", but already the region was becoming more Semitic than Sumerian, with the rise in power of the Akkadian speaking Semites in Assyria and elsewhere, and the influx of waves of Semitic Martu (Amorites) who were to found several competing local powers including Isin, Larsa, Eshnunna and eventually Babylon. The last of these eventually came to dominate the south of Mesopotamia as the Babylonian Empire, just as the Old Assyrian Empire had already done so in the north from the late 21st century BC. The Sumerian language continued as a sacerdotal language taught in schools in Babylonia and Assyria, much as Latin was used in the Medieval period, for as long as cuneiform was utilized.
How long did the Babylonians and Assyrians continue to teach the Sumerian language in their schools?
A: for as long as cuneiform was utilized.

A person can be exposed to uranium (or its radioactive daughters, such as radon) by inhaling dust in air or by ingesting contaminated water and food. The amount of uranium in air is usually very small; however, people who work in factories that process phosphate fertilizers, live near government facilities that made or tested nuclear weapons, live or work near a modern battlefield where depleted uranium weapons have been used, or live or work near a coal-fired power plant, facilities that mine or process uranium ore, or enrich uranium for reactor fuel, may have increased exposure to uranium. Houses or structures that are over uranium deposits (either natural or man-made slag deposits) may have an increased incidence of exposure to radon gas. The Occupational Safety and Health Administration (OSHA) has set the permissible exposure limit for uranium exposure in the workplace as 0.25 mg/m3 over an 8-hour workday. The National Institute for Occupational Safety and Health (NIOSH) has set a recommended exposure limit (REL) of 0.2 mg/m3 over an 8-hour workday and a short-term limit of 0.6 mg/m3. At levels of 10 mg/m3, uranium is immediately dangerous to life and health.
What does REL stand for?
A: recommended exposure limit

Traditionally, Espanyol was seen by the vast majority of Barcelona's citizens as a club which cultivated a kind of compliance to the central authority, in stark contrast to Barca's revolutionary spirit. Also in the 1960s and 1970s, while FC Barcelona acted as an integrating force for Catalonia's new arrivals from poorer regions of Spain expecting to find a better life, Espanyol drew their support mainly from sectors close to the regime such as policemen, military officers, civil servants and career fascists.
What type of supporters did Barcelona attract?
A:
Catalonia's new arrivals
