In this task, you are given a question and a context passage. You have to answer the question based on the given passage.

Input: Consider Input: What is the area of expertise of scientists who want to measure radiance from vegetation canopies?, Context: Oxygen presents two spectrophotometric absorption bands peaking at the wavelengths 687 and 760 nm. Some remote sensing scientists have proposed using the measurement of the radiance coming from vegetation canopies in those bands to characterize plant health status from a satellite platform. This approach exploits the fact that in those bands it is possible to discriminate the vegetation's reflectance from its fluorescence, which is much weaker. The measurement is technically difficult owing to the low signal-to-noise ratio and the physical structure of vegetation; but it has been proposed as a possible method of monitoring the carbon cycle from satellites on a global scale.

Output: remote sensing

Input: Consider Input: When did Zahm die?, Context: Father Joseph Carrier, C.S.C. was Director of the Science Museum and the Library and Professor of Chemistry and Physics until 1874. Carrier taught that scientific research and its promise for progress were not antagonistic to the ideals of intellectual and moral culture endorsed by the Church. One of Carrier's students was Father John Augustine Zahm (18511921) who was made Professor and Co-Director of the Science Department at age 23 and by 1900 was a nationally prominent scientist and naturalist. Zahm was active in the Catholic Summer School movement, which introduced Catholic laity to contemporary intellectual issues. His book Evolution and Dogma (1896) defended certain aspects of evolutionary theory as true, and argued, moreover, that even the great Church teachers Thomas Aquinas and Augustine taught something like it. The intervention of Irish American Catholics in Rome prevented Zahm's censure by the Vatican. In 1913, Zahm and former President Theodore Roosevelt embarked on a major expedition through the Amazon.

Output: 1921

Input: Consider Input: Why was Gamal's brother named Izz al-Arab?, Context: Gamal Abdel Nasser was born on 15 January 1918 in Bakos, Alexandria, the first son of Fahima and Abdel Nasser Hussein. Nasser's father was a postal worker born in Beni Mur in Upper Egypt and raised in Alexandria, and his mother's family came from Mallawi, el-Minya. His parents married in 1917, and later had two more boys, Izz al-Arab and al-Leithi. Nasser's biographers Robert Stephens and Said Aburish wrote that Nasser's family believed strongly in the "Arab notion of glory", since the name of Nasser's brother, Izz al-Arab, translates to "Glory of the Arabs"a rare name in Egypt.
Output: family believed strongly in the "Arab notion of glory"
