[Q]: Question: "__ is a key component of fuel cells, which react hydrogen with oxygen to produce electricity, heat, and water." Context: "Hydrogen is highly soluble in many rare earth and transition metals and is soluble in both nanocrystalline and amorphous metals. Hydrogen solubility in metals is influenced by local distortions or impurities in the crystal lattice. These properties may be useful when hydrogen is purified by passage through hot palladium disks, but the gas's high solubility is a metallurgical problem, contributing to the embrittlement of many metals, complicating the design of pipelines and storage tanks." Answer:
****
[A]: palladium

input: Please answer the following: Question: "Which of the following is not one of the things that cause detours: predation risk, differential wind conditions, or theoretical analyses?" Context: "Theoretical analyses show that detours that increase flight distance by up to 20% will often be adaptive on aerodynamic grounds - a bird that loads itself with food to cross a long barrier flies less efficiently. However some species show circuitous migratory routes that reflect historical range expansions and are far from optimal in ecological terms. An example is the migration of continental populations of Swainson's thrush Catharus ustulatus, which fly far east across North America before turning south via Florida to reach northern South America; this route is believed to be the consequence of a range expansion that occurred about 10,000 years ago. Detours may also be caused by differential wind conditions, predation risk, or other factors." Answer:
++++++++++
output: Theoretical analyses

Problem: Question: "in 2004 solar thermal plant was the what of its kind?" Context: "In 2004, a large share of natural gas reserves in Iran were untapped. The addition of new hydroelectric stations and the streamlining of conventional coal and oil-fired stations increased installed capacity to 33,000 megawatts. Of that amount, about 75% was based on natural gas, 18% on oil, and 7% on hydroelectric power. In 2004, Iran opened its first wind-powered and geothermal plants, and the first solar thermal plant is to come online in 2009. Iran is the third country in the world to have developed GTL technology." Answer:

A: first

Problem: Given the question: Question: "What is the Tengyur?" Context: "Sanskrit has also influenced Sino-Tibetan languages through the spread of Buddhist texts in translation. Buddhism was spread to China by Mahayana missionaries sent by Ashoka, mostly through translations of Buddhist Hybrid Sanskrit. Many terms were transliterated directly and added to the Chinese vocabulary. Chinese words like chana (Devanagari: ksana 'instantaneous period') were borrowed from Sanskrit. Many Sanskrit texts survive only in Tibetan collections of commentaries to the Buddhist teachings, the Tengyur." Answer:
++++++++++++++++++++++++++++++++
