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: Suppose there are 2 more newborns, then which number will be increased, 65%, 15.1% or 19.9%?, Context: As of 2000[update], children and teenagers (0–19 years old) make up 15.1% of the population, while adults (20–64 years old) make up 65% and seniors (over 64 years old) make up 19.9%.

Output: 15.1%


Input: Consider Input: What other schools look for the same qualities in teachers as does Western Europe?, Context: A modern example of school discipline in North America and Western Europe relies upon the idea of an assertive teacher who is prepared to impose their will upon a class. Positive reinforcement is balanced with immediate and fair punishment for misbehavior and firm, clear boundaries define what is appropriate and inappropriate behavior. Teachers are expected to respect their students; sarcasm and attempts to humiliate pupils are seen as falling outside of what constitutes reasonable discipline.[verification needed]


Output: North America
