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: Although Montana is a large state, it has a low what?, Context: Montana i/mɒnˈtænə/ is a state in the Western region of the United States. The state's name is derived from the Spanish word montaña (mountain). Montana has several nicknames, although none official, including "Big Sky Country" and "The Treasure State", and slogans that include "Land of the Shining Mountains" and more recently "The Last Best Place". Montana is ranked 4th in size, but 44th in population and 48th in population density of the 50 United States. The western third of Montana contains numerous mountain ranges. Smaller island ranges are found throughout the state. In total, 77 named ranges are part of the Rocky Mountains.

Output: population


Input: Consider Input: What were Samurai used for?, Context: Emperor Meiji abolished the samurai's right to be the only armed force in favor of a more modern, western-style, conscripted army in 1873. Samurai became Shizoku (士族) who retained some of their salaries, but the right to wear a katana in public was eventually abolished along with the right to execute commoners who paid them disrespect. The samurai finally came to an end after hundreds of years of enjoyment of their status, their powers, and their ability to shape the government of Japan. However, the rule of the state by the military class was not yet over. In defining how a modern Japan should be, members of the Meiji government decided to follow the footsteps of the United Kingdom and Germany, basing the country on the concept of noblesse oblige. Samurai were not a political force under the new order. With the Meiji reforms in the late 19th century, the samurai class was abolished, and a western-style national army was established. The Imperial Japanese Armies were conscripted, but many samurai volunteered as soldiers, and many advanced to be trained as officers. Much of the Imperial Army officer class was of samurai origin, and were highly motivated, disciplined, and exceptionally trained.


Output: army
