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:
What type of equipment is used with liquid oxygen but not other methods of oxygen storage?, Context: Oxygen storage methods include high pressure oxygen tanks, cryogenics and chemical compounds. For reasons of economy, oxygen is often transported in bulk as a liquid in specially insulated tankers, since one liter of liquefied oxygen is equivalent to 840 liters of gaseous oxygen at atmospheric pressure and 20 °C (68 °F). Such tankers are used to refill bulk liquid oxygen storage containers, which stand outside hospitals and other institutions with a need for large volumes of pure oxygen gas. Liquid oxygen is passed through heat exchangers, which convert the cryogenic liquid into gas before it enters the building. Oxygen is also stored and shipped in smaller cylinders containing the compressed gas; a form that is useful in certain portable medical applications and oxy-fuel welding and cutting.
answer:
heat exchangers


question:
Who were the Spanish monarchs that financed Christopher Columbus?, Context: The 1469 marriage of Isabella I of Castile and Ferdinand II of Aragon and the 1479 death of John II of Aragon led to the creation of modern-day Spain. In 1492, Granada was captured from the Moors, thereby completing the Reconquista. Portugal had during the 15th century – particularly under Henry the Navigator – gradually explored the coast of Africa, and in 1498, Vasco da Gama found the sea route to India. The Spanish monarchs met the Portuguese challenge by financing the expedition of Christopher Columbus to find a western sea route to India, leading to the discovery of the Americas in 1492.
answer:
Isabella I of Castile and Ferdinand II of Aragon


question:
How would you ask for comics in France?, Context: Cross-cultural study of comics is complicated by the great difference in meaning and scope of the words for "comics" in different languages. The French term for comics, bandes dessinées ("drawn strip") emphasizes the juxtaposition of drawn images as a defining factor, which can imply the exclusion of even photographic comics. The term manga is used in Japanese to indicate all forms of comics, cartooning, and caricature.
answer:

bandes dessinées
