Answer the question from the given passage. Your answer should be directly extracted from the passage, and it should be a single entity, name, or number, not a sentence.

Input: Consider Input: 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 does increased oxygen concentrations in the patient's lungs displace?

Output: carbon monoxide


Input: Consider Input: Passage: The following four timelines show the geologic time scale. The first shows the entire time from the formation of the Earth to the present, but this compresses the most recent eon. Therefore, the second scale shows the most recent eon with an expanded scale. The second scale compresses the most recent era, so the most recent era is expanded in the third scale. Since the Quaternary is a very short period with short epochs, it is further expanded in the fourth scale. The second, third, and fourth timelines are therefore each subsections of their preceding timeline as indicated by asterisks. The Holocene (the latest epoch) is too small to be shown clearly on the third timeline on the right, another reason for expanding the fourth scale. The Pleistocene (P) epoch. Q stands for the Quaternary period. Question: Which timeline is further expanded in the fourth scale?

Output: Quaternary


Input: Consider Input: Passage: The city has two universities — Newcastle University and Northumbria University. Newcastle University has its origins in the School of Medicine and Surgery, established in 1834 and became independent from Durham University on 1 August 1963 to form the University of Newcastle upon Tyne. Newcastle University is now one of the UK's leading international universities. It won the coveted Sunday Times University of the Year award in 2000. Northumbria University has its origins in the Newcastle Polytechnic, established in 1969 and became the University of Northumbria at Newcastle in 1992 as part of the UK-wide process in which polytechnics became new universities. Northumbria University was voted 'Best New University' by The Times Good University Guide 2005 and also won a much coveted company award of the 'Most IT enabled organisation' (in the UK), by the IT industry magazine Computing. Question: Which university has its origins in a school dealing with medicine and surgery?
Output: Newcastle University
