Problem: Incandescent light bulb:

Incandescent light bulbs consist of an air-tight glass enclosure (the envelope, or bulb) with a filament of tungsten wire inside the bulb, through which an electric current is passed. Contact wires and a base with two (or more) conductors provide electrical connections to the filament. Incandescent light bulbs usually contain a stem or glass mount anchored to the bulb's base that allows the electrical contacts to run through the envelope without air or gas leaks. Small wires embedded in the stem in turn support the filament and its lead wires.

What has four conductors that provide electrical connections to the filament?

Problem: Uranium-235 was the first isotope that was found to be fissile. Other naturally occurring isotopes are fissionable, but not fissile. On bombardment with slow neutrons, its uranium-235 isotope will most of the time divide into two smaller nuclei, releasing nuclear binding energy and more neutrons. If too many of these neutrons are absorbed by other uranium-235 nuclei, a nuclear chain reaction occurs that results in a burst of heat or (in special circumstances) an explosion. In a nuclear reactor, such a chain reaction is slowed and controlled by a neutron poison, absorbing some of the free neutrons. Such neutron absorbent materials are often part of reactor control rods (see nuclear reactor physics for a description of this process of reactor control).
What isotope of uranium was the last to be found fissile?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Besides the obligation, many children had to help support their families financially; another factor that influenced child labour was the demographic changes that occurred in the eighteenth century. By the end of the eighteenth century, 20 percent of the population was made up of children between the ages of 5 and 14. Due to this substantial shift in available workers, and the development of the industrial revolution, children began to work earlier in life in companies outside of the home. Yet, even though there was an increase of child labour in factories such as cotton textiles, there consistently was large numbers of children working in the field of agriculture and domestic production.
What type of support did child give to their families by working?
A: financially

Question: The Romans liked bright colors, and many Roman villas were decorated with vivid red murals. The pigment used for many of the murals was called vermilion, and it came from the mineral cinnabar, a common ore of mercury. It was one of the finest reds of ancient times – the paintings have retained their brightness for more than twenty centuries. The source of cinnabar for the Romans was a group of mines near Almadén, southwest of Madrid, in Spain. Working in the mines was extremely dangerous, since mercury is highly toxic; the miners were slaves or prisoners, and being sent to the cinnabar mines was a virtual death sentence.
Is there an answer to this question: What was the pigment called that was used for the painting of Roman villas?

Answer: unanswerable
