Here is a question about this article: The overseas Chinese community has played a large role in the development of the economies in the region. These business communities are connected through the bamboo network, a network of overseas Chinese businesses operating in the markets of Southeast Asia that share common family and cultural ties. The origins of Chinese influence can be traced to the 16th century, when Chinese migrants from southern China settled in Indonesia, Thailand, and other Southeast Asian countries. Chinese populations in the region saw a rapid increase following the Communist Revolution in 1949, which forced many refugees to emigrate outside of China.
What is the answer to this question: The rise of Chinese population saw a rapid increase during which revolution?

So... Communist Revolution

Here is a question about this article: In the US, one kilowatt-hour (3.6 MJ) of electricity currently causes an average 1.34 pounds (610 g) of CO
2 emission. Assuming the average light bulb is on for 10 hours a day, a 40-watt bulb will cause 196 pounds (89 kg) of CO
2 emission per year. The 6-watt LED equivalent will only cause 30 pounds (14 kg) of CO
2 over the same time span. A building's carbon footprint from lighting can therefore be reduced by 85% by exchanging all incandescent bulbs for new LEDs if a building previously used only incandescent bulbs.
What is the answer to this question: How much CO2 emission would a 40-watt light bulb produce after 10 hours?
****
So... 196 pounds

Here is a question about this article: At the beginning of the Han dynasty, every male commoner aged twenty-three was liable for conscription into the military. The minimum age for the military draft was reduced to twenty after Emperor Zhao's (r. 8774 BC) reign. Conscripted soldiers underwent one year of training and one year of service as non-professional soldiers. The year of training was served in one of three branches of the armed forces: infantry, cavalry or navy. The year of active service was served either on the frontier, in a king's court or under the Minister of the Guards in the capital. A small professional (paid) standing army was stationed near the capital.
What is the answer to this question: At what age could a male common expect to be conscripted into the military?
****
So...
twenty-three
