Question: When was Beloit college founded? Passage 1:The Crag Group is a geological group outcropping in East Anglia, UK and adjacent areas of the North Sea. Its age ranges from approximately 4.4 to 0.478 million years BP, spanning the late Pliocene and early to middle Pleistocene epochs. It comprises a range of marine and estuarine sands, gravels, silts and clays deposited in a relatively shallow-water, tidally-dominated marine embayment on the western margins of the North Sea basin. The sands are characteristically dark green from glauconite but weather bright orange, with haematite 'iron pans' forming. The lithology of the lower part of the Group is almost entirely flint. The highest formation in the Group, the Wroxham Crag, contains over 10% of far-travelled lithologies, notably quartzite and vein quartz from the Midlands, igneous rocks from Wales, and chert from the Upper Greensand of southeastern England. This exotic rock component was introduced by rivers such as the Bytham River and Proto-Thames. 
 Passage 2:Mikva is the daughter of Judge Abner Mikva and Zorita ("Zoe") (nee Wise) Mikva. Mikva and her two sisters were raised in Evanston, Illinois, and attended public schools. She earned her B.A. in theater at Beloit College in 1974, working after graduation as a paralegal at the law firm Jenner & Block. She then attended Northwestern University Pritzker School of Law, graduating cum laude and Order of the Coif in 1980. Following graduation, she served as law clerk to Judge Prentice Marshall of the United States District Court for the Northern District of Illinois, and then to Justice William J. Brennan, Jr., of the United States Supreme Court. After her clerkships, Mikva practiced law in Chicago as a partner at Abrahamson Vorachek & Mikva and Seliger & Mikva, specializing in civil rights and employment law, and in criminal defense with Patrick A. Tuite & Associates. 
 Passage 3:Kifle was born in Adi Billai in Eritrea's Debub Region. He made his first international appearance for Eritrea at the age of 21, running in the 3000 metres at the 1999 IAAF World Indoor Championships. He finished in last place and was over twenty seconds behind the rest of the runners. His first international outdoor competition followed later that year and he ran in the heats of the 5000 metres at the 1999 World Championships in Athletics in Seville. In 2000 he came 61st at the 2000 IAAF World Cross Country Championships and made his Olympic debut with a performance in the heats of the 10,000 metres at the 2000 Sydney Olympics. He began to improve from the 2002 season onwards: he was eighth in the long race at the 2000 IAAF World Cross Country Championships, fourth at the 2002 IAAF World Half Marathon Championships with a time of 1:01:05 hours, and came sixth over 5000 m at the 2002 African Championships in Athletics. He also won the Cursa de Bombers 10K in Spain that year.
