Input: Read this: With high cost of labor in developed countries, production automation has become increasingly popular. Rather than being assembled by hand, mosaics designed using computer aided design (CAD) software can be assembled by a robot. Production can be greater than 10 times faster with higher accuracy. But these "computer" mosaics have a different look than hand-made "artisanal" mosaics. With robotic production, colored tiles are loaded into buffers, and then the robot picks and places tiles individually according to a command file from the design software.
Question: How much faster is automated creation over handmade?

Output: 10 times faster

Input: Read this: Infrared is used in night vision equipment when there is insufficient visible light to see. Night vision devices operate through a process involving the conversion of ambient light photons into electrons that are then amplified by a chemical and electrical process and then converted back into visible light. Infrared light sources can be used to augment the available ambient light for conversion by night vision devices, increasing in-the-dark visibility without actually using a visible light source.
Question: By what process do night vision devices convert infrared into photons?

Output: unanswerable

Input: Read this: Melbourne is an international cultural centre, with cultural endeavours spanning major events and festivals, drama, musicals, comedy, music, art, architecture, literature, film and television. The climate, waterfront location and nightlife make it one of the most vibrant destinations in Australia.

Output: just under two million

Input: Read this: The climate of the coastal plain is influenced by the Atlantic Ocean, which keeps conditions mild in winter and moderate, although humid, in summer. The highest coastal, daytime temperature averages less than 89 F (32 C) during summer months. The coast has mild temperatures in winter, with daytime highs rarely below 40 F (4 C). The average daytime temperature in the coastal plain is usually in the mid-50s F (1114 C) in winter. Temperatures in the coastal plain only occasionally drop below the freezing point at night. The coastal plain averages only around 1 inch (2.5 cm) of snow or ice annually, and in many years, there may be no snow or ice at all.
Question: How often do temperatures on the coastal plain of NC drop below freezing at night?

Output:
occasionally
