PROBLEM: Question: Was John Wood living in Hull the year Cousin was born? Passage:Anne Ross Cousin was born in Hull, England on 27 April 1824. She was the only child of Dr. David Ross Cundell, a former assistant surgeon with the 33rd regiment at the Battle of Waterloo, and moved with her family to Leith soon after her birth. She received a private education and became a skilled pianist under John Muir Wood. In 1847, she married William Cousin, a minister of the Free Church of Scotland, then serving at a local Presbyterian church in Chelsea, and with whom she would have six children. Shortly after their marriage, William was called to minister to the Free Church in Irvine, North Ayrshire, and then in Melrose in 1859. During this time, Anne began writing church hymns for her husband's services and many of these became very popular in Britain during the mid-to late 19th century.

PROBLEM: Question: Between the agency that implemented EPA standards and provide perpetual care for some sites and the one that reviewed cleanups and license sites to states or the DOE for perpetual care, which is the oldest?  Passage:The Uranium Mill Tailings Radiation Control Act (1978) is a United States environmental law that amended the Atomic Energy Act of 1954 and authorized the Environmental Protection Agency to establish health and environmental standards for the stabilization, restoration, and disposal of uranium mill waste. Title 1 of the Act required the EPA to set environmental protection standards consistent with the Resource Conservation and Recovery Act, including groundwater protection limits; the Department of Energy to implement EPA standards and provide perpetual care for some sites; and the Nuclear Regulatory Commission to review cleanups and license sites to states or the DOE for perpetual care. Title 1 established a uranium mill remedial action program jointly funded by the federal government and the state. Title 1 of the Act also designated 22 inactive uranium mill sites for remediation, resulting in the containment of 40 million cubic yards of low-level radioactive material in UMTRCA Title 1 holding cells.
