Ex Input:
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.

Ex Output:
What device is used to treat various conditions such as carbon monoxide poisoning?


Ex Input:
British settlers outnumbered the French 20 to 1 with a population of about 1.5 million ranged along the eastern coast of the continent, from Nova Scotia and Newfoundland in the north, to Georgia in the south. Many of the older colonies had land claims that extended arbitrarily far to the west, as the extent of the continent was unknown at the time their provincial charters were granted. While their population centers were along the coast, the settlements were growing into the interior. Nova Scotia, which had been captured from France in 1713, still had a significant French-speaking population. Britain also claimed Rupert's Land, where the Hudson's Bay Company traded for furs with local tribes.

Ex Output:
What was the ratio of British settler to French?


Ex Input:
Throughout its existence, Warsaw has been a multi-cultural city. According to the 1901 census, out of 711,988 inhabitants 56.2% were Catholics, 35.7% Jews, 5% Greek orthodox Christians and 2.8% Protestants. Eight years later, in 1909, there were 281,754 Jews (36.9%), 18,189 Protestants (2.4%) and 2,818 Mariavites (0.4%). This led to construction of hundreds of places of religious worship in all parts of the town. Most of them were destroyed in the aftermath of the Warsaw Uprising of 1944. After the war, the new communist authorities of Poland discouraged church construction and only a small number were rebuilt.

Ex Output:

What type of city has Warsaw been for as long as it's been a city?
