Question: Where is the Centennial Light?, Context: The relationships above are valid for only a few percent change of voltage around rated conditions, but they do indicate that a lamp operated at much lower than rated voltage could last for hundreds of times longer than at rated conditions, albeit with greatly reduced light output. The "Centennial Light" is a light bulb that is accepted by the Guinness Book of World Records as having been burning almost continuously at a fire station in Livermore, California, since 1901. However, the bulb emits the equivalent light of a four watt bulb. A similar story can be told of a 40-watt bulb in Texas that has been illuminated since 21 September 1908. It once resided in an opera house where notable celebrities stopped to take in its glow, and was moved to an area museum in 1977.

Answer: a fire station


Question: How does a chestnut tree form its heartwood?, Context: The term heartwood derives solely from its position and not from any vital importance to the tree. This is evidenced by the fact that a tree can thrive with its heart completely decayed. Some species begin to form heartwood very early in life, so having only a thin layer of live sapwood, while in others the change comes slowly. Thin sapwood is characteristic of such species as chestnut, black locust, mulberry, osage-orange, and sassafras, while in maple, ash, hickory, hackberry, beech, and pine, thick sapwood is the rule. Others never form heartwood.

Answer: the change comes slowly


Question: Which of the following has the lowest religious observance: Europe, the United States, or South America?, Context: In Europe, there has been a general move away from religious observance and belief in Christian teachings and a move towards secularism. The Enlightenment is largely responsible for the spread of secularism. Several scholars have argued for a link between the rise of secularism and Protestantism, attributing it to the wide-ranging freedom in the Protestant countries. In North America, South America and Australia Christian religious observance is much higher than in Europe. United States remains particularly religious in comparison to other developed countries. South America, historically Roman Catholic, has experienced a large Evangelical and Pentecostal infusion in the 20th and 21st centuries.

Answer:
Europe
