Question: Passage: Hyperbaric (high-pressure) medicine uses special oxygen chambers to increase the partial pressure of O
2 around the patient and, when needed, the medical staff. Carbon monoxide poisoning, gas gangrene, and decompression sickness (the 'bends') are sometimes treated using these devices. Increased O
2 concentration in the lungs helps to displace carbon monoxide from the heme group of hemoglobin. Oxygen gas is poisonous to the anaerobic bacteria that cause gas gangrene, so increasing its partial pressure helps kill them. Decompression sickness occurs in divers who decompress too quickly after a dive, resulting in bubbles of inert gas, mostly nitrogen and helium, forming in their blood. Increasing the pressure of O
2 as soon as possible is part of the treatment. Question: What device is used to treat various conditions such as carbon monoxide poisoning?

Answer: oxygen chambers


Question: Passage: The university runs a number of academic institutions and programs apart from its undergraduate and postgraduate schools. It operates the University of Chicago Laboratory Schools (a private day school for K-12 students and day care), the Sonia Shankman Orthogenic School (a residential treatment program for those with behavioral and emotional problems), and four public charter schools on the South Side of Chicago administered by the university's Urban Education Institute. In addition, the Hyde Park Day School, a school for students with learning disabilities, maintains a location on the University of Chicago campus. Since 1983, the University of Chicago has maintained the University of Chicago School Mathematics Project, a mathematics program used in urban primary and secondary schools. The university runs a program called the Council on Advanced Studies in the Social Sciences and Humanities, which administers interdisciplinary workshops to provide a forum for graduate students, faculty, and visiting scholars to present scholarly work in progress. The university also operates the University of Chicago Press, the largest university press in the United States. Question: What does the Urban Education Institute help run?

Answer: four public charter schools


Question: Passage: Jacksonville is in the First Coast region of northeast Florida and is centered on the banks of the St. Johns River, about 25 miles (40 km) south of the Georgia state line and about 340 miles (550 km) north of Miami. The Jacksonville Beaches communities are along the adjacent Atlantic coast. The area was originally inhabited by the Timucua people, and in 1564 was the site of the French colony of Fort Caroline, one of the earliest European settlements in what is now the continental United States. Under British rule, settlement grew at the narrow point in the river where cattle crossed, known as Wacca Pilatka to the Seminole and the Cow Ford to the British. A platted town was established there in 1822, a year after the United States gained Florida from Spain; it was named after Andrew Jackson, the first military governor of the Florida Territory and seventh President of the United States. Question: What historical figure was Jacksonville named after?

Answer:
Andrew Jackson
