Example Input: During this time, Alexander adopted some elements of Persian dress and customs at his court, notably the custom of proskynesis, either a symbolic kissing of the hand, or prostration on the ground, that Persians showed to their social superiors. The Greeks regarded the gesture as the province of deities and believed that Alexander meant to deify himself by requiring it. This cost him the sympathies of many of his countrymen, and he eventually abandoned it. A plot against his life was revealed, and one of his officers, Philotas, was executed for failing to alert Alexander. The death of the son necessitated the death of the father, and thus Parmenion, who had been charged with guarding the treasury at Ecbatana, was assassinated at Alexander's command, to prevent attempts at vengeance. Most infamously, Alexander personally killed the man who had saved his life at Granicus, Cleitus the Black, during a violent drunken altercation at Maracanda (modern day Samarkand in Uzbekistan), in which Cleitus accused Alexander of several judgemental mistakes and most especially, of having forgotten the Macedonian ways in favour of a corrupt oriental lifestyle. Later, in the Central Asian campaign, a second plot against his life was revealed, this one instigated by his own royal pages. His official historian, Callisthenes of Olynthus, was implicated in the plot; however, historians have yet to reach a consensus regarding this involvement. Callisthenes had fallen out of favor by leading the opposition to the attempt to introduce proskynesis. <sep>What are the details of the second plot on Alexander's life in the Central Asian campaign?<sep>Instigated by his own royal pages
Example Output: Yes

Example Input: New Horizons: Exhausted after the Civil War, Spain remained on the sidelines during World War II and began to recover economically under the oppressive, law-and-order regime of Franco. There had been a foretaste of elite foreign tourism in the 1920s, but it was the late 1950s when the rest of Europe began sun-seeking pilgrimages to Spain. Tourism exploded into an annual southern migration, transforming the Spanish economy, landscape, and society. Eager to capitalize, the country poured its soul into mass tourism, which triggered a rash of indiscriminate building on the southern and eastern coastlines, with scant regard for tradition or aesthetics. But after so many years closed off from the rest of Europe, of equal significance was the injection of foreign influences into Franco's once hermetically sealed Spain. Mallorca and Menorca in particular saw explosive growth in tourism; by the 1970s, the Balearics were one of Europe's most popular holiday destinations. Franco named as his successor the grandson of Alfonso XIII, who was enthroned as King Juan Carlos I when the dictator died in 1975. To the dismay of Franco diehards, the king brilliantly managed the transition to democracy, then stood back to allow it full rein, even intervening during a brief attempt at a military coup. After many years of repression, new freedoms and autonomy were granted to Spanish regions, including the Balearics, and their languages and cultures enjoyed a long-desired renaissance. More a part of Europe than ever before, Spain joined the European Community (now European Union) in 1986, giving further boost to a booming economy. The tourist industry continued to expand, and though it became one of the top two income earners in Spain, a realization that unrestricted mass tourism was leading to damaging long-term consequences also began to grow. By the late 1990s, a new emphasis on quality and, especially in the Balearics, on safeguarding the environment had finally taken roottoo late for many environmentalists, but hopefully still in time to preserve much of the natural beauty and unique character of the Las Islas Baleares. <sep>Why was Spain so isolated and what event happened that allowed Mallorca and Menorca to see explosions in tourism?<sep>Spain was surrounded by enemies
Example Output: No

Example Input: Fossils may form in other ways. Fossils can be preserved almost completely. In this process, the organism doesnt change much. As seen below, tree sap may cover an organism. With time, the sap hardens. It turns to into amber. The original organism is preserved. This is very exciting for scientists. They are able to study the DNA of the organism that no longer lives on Earth. Some animals have been found frozen in ice. Others have been found in tar pits after falling in. Molds and casts are another way organisms can be fossilized. Have you ever walked in soft mud and left footprints? Once in a while, these traces of organisms can be preserved. In this case, nothing is left of the organism. A mold is an imprint of an organism that is preserved in rock. The organisms remains break down completely. There is nothing left of the original plant and animal. <sep>What is a mold?<sep>Fossil fuel
Example Output:
No
