Input: Consider 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>Who lost their lives when a plot against Alexander's life was revealed?<sep>Cleitus the Black

Output: No


Input: Consider Input: I wondered if that were my case--if I rode out for honour, and not for the pure pleasure of the riding.  And I marvelled more to see the two of us, both lovers of one lady and eager rivals, burying for the nonce our feuds, and with the same hope serving the same cause.  We slept the night at Aird's store, and early the next morning found Ringan.  A new Ringan indeed, as unlike the buccaneer I knew as he was unlike the Quaker.  He was now the gentleman of Breadalbane, dressed for the part with all the care of an exquisite.  He rode a noble roan, in his Spanish belt were stuck silver-hafted pistols, and a long sword swung at his side.  When I presented Grey to him, he became at once the cavalier, as precise in his speech and polite in his deportment as any Whitehall courtier.  They talked high and disposedly of genteel matters, and you would have thought that that red-haired pirate had lived his life among proud lords and high-heeled ladies.  That is ever the way of the Highlander.  He alters like a clear pool to every mood of the sky, so that the shallow observer might forget how deep the waters are. <sep>Who talked high and disposedly of genteel matters?<sep>The author

Output: No


Input: Consider Input: Littlefoot 's grandfather one night tells the children a story about `` The Lone Dinosaur '' , a legendary longneck who once protected the Great Valley from the most ferocious sharptooth ever to live . A fight ensued , which led to the Sharptooth 's death . However , the sharptooth left `` The Lone Dinosaur '' with a scar slashed across his right eye . Soon after the battle , a huge monolith that resembled a proud sauropod , having life-sized Sharptooth teeth arranged around his neck , came out of the ground during an earthquake . The dinosaurs called it `` Saurus Rock '' . The legend also states that if anyone damages the monolith , bad luck would descend upon the valley . A few days later when the kids are playing , Littlefoot accidentally falls off a cliff . Just before he hits the ground , a gruff Diplodocus rescues him . This longneck introduces himself only as `` Doc '' and gives no knowledge of his history . Littlefoot is intrigued by this newcomer , who is scarred across one eye and displays prior knowledge of the Great Valley 's topography . For the preceding reasons , Littlefoot assumes that Doc is the Lone Dinosaur . He tells his friends this , narrating an apparently extemporaneous legend to support his assumption . Inspired , Cera 's infant nieces , the twins Dinah and Dana , go to Saurus Rock without anyone noticing . Later when the friends are playing , they notice that Dinah and Dana are missing . Recalling their talk of the day before , they go to Saurus Rock to find them . <sep>Who was the enemy of the Dinosaur?<sep>Littlefoot's Grandpa
