instruction:
In this task, you are given a question and a context passage. You have to answer the question based on the given passage.
question:
Which element is mentioned?, Context: Breathing pure O2 in space applications, such as in some modern space suits, or in early spacecraft such as Apollo, causes no damage due to the low total pressures used. In the case of spacesuits, the O2 partial pressure in the breathing gas is, in general, about 30 kPa (1.4 times normal), and the resulting O2 partial pressure in the astronaut's arterial blood is only marginally more than normal sea-level O2 partial pressure (for more information on this, see space suit and arterial blood gas).
answer:
O2


question:
What is Sand Point at the tip of?, Context: The main coastal towns are, from the west to the north-east, Minehead, Watchet, Burnham-on-Sea, Weston-super-Mare, Clevedon and Portishead. The coastal area between Minehead and the eastern extreme of the administrative county's coastline at Brean Down is known as Bridgwater Bay, and is a National Nature Reserve. North of that, the coast forms Weston Bay and Sand Bay whose northern tip, Sand Point, marks the lower limit of the Severn Estuary. In the mid and north of the county the coastline is low as the level wetlands of the levels meet the sea. In the west, the coastline is high and dramatic where the plateau of Exmoor meets the sea, with high cliffs and waterfalls.
answer:
Sand Bay


question:
The students at the boarding house had what in common that is the last thing mentioned?, Context: In 1827, soon after the death of Chopin's youngest sister Emilia, the family moved from the Warsaw University building, adjacent to the Kazimierz Palace, to lodgings just across the street from the university, in the south annex of the Krasiński Palace on Krakowskie Przedmieście,[n 5] where Chopin lived until he left Warsaw in 1830.[n 6] Here his parents continued running their boarding house for male students; the Chopin Family Parlour (Salonik Chopinów) became a museum in the 20th century. In 1829 the artist Ambroży Mieroszewski executed a set of portraits of Chopin family members, including the first known portrait of the composer.[n 7]
answer:

male
