Question: "Who was not the first person to write down the idea regarding variable resistance in a telephone?" Context: "The question of priority for the variable resistance feature of the telephone was raised by the examiner before he approved Bell's patent application. He told Bell that his claim for the variable resistance feature was also described in Gray's caveat. Bell pointed to a variable resistance device in Bell's previous application in which Bell described a cup of mercury, not water. Bell had filed the mercury application at the patent office a year earlier on February 25, 1875, long before Elisha Gray described the water device. In addition, Gray abandoned his caveat, and because he did not contest Bell's priority, the examiner approved Bell's patent on March 3, 1876. Gray had reinvented the variable resistance telephone, but Bell was the first to write down the idea and the first to test it in a telephone." Answer:

Answer: Gray

Question: "In big trees, what may be inferior to heartwood from the same log?" Context: "Different pieces of wood cut from a large tree may differ decidedly, particularly if the tree is big and mature. In some trees, the wood laid on late in the life of a tree is softer, lighter, weaker, and more even-textured than that produced earlier, but in other trees, the reverse applies. This may or may not correspond to heartwood and sapwood. In a large log the sapwood, because of the time in the life of the tree when it was grown, may be inferior in hardness, strength, and toughness to equally sound heartwood from the same log. In a smaller tree, the reverse may be true." Answer:
----
Answer: sapwood

Question: "Why did India refuse China's demands?" Context: "India rejected Chinese demands that the torch route be clear of India's 150,000-strong Tibetan exile community, by which they required a ban on congregation near the curtailed 3 km route. In response Indian officials said India was a democracy, and "a wholesale ban on protests was out of the question". Contradicting some other reports, Indian officials also refused permission to the "Olympic Holy Flame Protection Unit". The combined effect is a "rapid deterioration" of relations between India and China. Meanwhile, the Tibetan government in exile, which is based in India, has stated that it did not support the disruption of the Olympic torch relay." Answer:
----
Answer:
India was a democracy, and "a wholesale ban on protests was out of the question"
