Problem: Alexander Sergeyevich Pushkin (/'pUSkIn/; Russian: Aleksandr Sergeevich Pushkin, tr. Aleksandr Sergeyevich Pushkin; IPA: [aljI'ksandr sjI'rgjejIvjItc 'puskjIn]; 6 June [O.S. 26 May] 1799 - 10 February [O.S. 29 January] 1837) was a Russian author of the Romantic era who is considered by many to be the greatest Russian poet and the founder of modern Russian literature. Pushkin was born into Russian nobility in Moscow. His matrilineal great grandfather was Abram Gannibal, who was brought over as a slave from what is now Cameroon. Pushkin published his first poem at the age of fifteen, and was widely recognized by the literary establishment by the time of his graduation from the Tsarskoye Selo Lyceum. While under the strict surveillance of the Tsar's political police and unable to publish, Pushkin wrote his most famous play, the drama Boris Godunov. His novel in verse, Eugene Onegin, was serialized between 1825 and 1832. Notoriously touchy about his honour, Pushkin fought as many as twenty-nine duels, and was fatally wounded in such an encounter with Georges-Charles de Heeckeren d'Anthes. Pushkin had accused D'Anthes, a French officer serving with the Chevalier Guard Regiment of attempting to seduce the poet's wife, Natalya Pushkina.

Question:
After the death of Spitamenes and his marriage to Roxana (Roshanak in Bactrian) to cement relations with his new satrapies, Alexander turned to the Indian subcontinent. He invited the chieftains of the former satrapy of Gandhara, in the north of what is now Pakistan, to come to him and submit to his authority. Omphis(Indian name Ambhi Kumar), the ruler of Taxila, whose kingdom extended from the Indus to the Hydaspes (Jhelum), complied, but the chieftains of some hill clans, including the Aspasioi and Assakenoi sections of the Kambojas (known in Indian texts also as Ashvayanas and Ashvakayanas), refused to submit. Ambhi hastened to relieve Alexander of his apprehension and met him with valuable presents, placing himself and all his forces at his disposal. Alexander not only returned Ambhi his title and the gifts but he also presented him with a wardrobe of "Persian robes, gold and silver ornaments, 30 horses and 1000 talents in gold". Alexander was emboldened to divide his forces, and Ambhi assisted Hephaestion and Perdiccas in constructing a bridge over the Indus where it bends at Hund (Fox 1973), supplied their troops with provisions, and received Alexander himself, and his whole army, in his capital city of Taxila, with every demonstration of friendship and the most liberal hospitality. On the subsequent advance of the Macedonian king, Taxiles accompanied him with a force of 5000 men and took part in the battle of the Hydaspes River. After that victory he was sent by Alexander in pursuit of Porus, to whom he was charged to offer favourable terms, but narrowly escaped losing his life at the hands of his old enemy. Subsequently, however, the two rivals were reconciled by the personal mediation of Alexander; and Taxiles, after having contributed zealously to the equipment of the fleet on the Hydaspes, was entrusted by the king with the government of the whole territory between that river and the Indus. A considerable accession of power was granted him after the death of Philip, son of Machatas; and he was allowed to retain his authority at the death of Alexander himself (323 BC), as well as in the subsequent partition of the provinces at Triparadisus, 321 BC. In the winter of 327/326 BC, Alexander personally led a campaign against these clans; the Aspasioi of Kunar valleys, the Guraeans of the Guraeus valley, and the Assakenoi of the Swat and Buner valleys. A fierce contest ensued with the Aspasioi in which Alexander was wounded in the shoulder by a dart, but eventually the Aspasioi lost. Alexander then faced the Assakenoi, who fought in the strongholds of Massaga, Ora and Aornos. The fort of Massaga was reduced only after days of bloody fighting, in which Alexander was wounded seriously in the ankle. According to Curtius, "Not only did Alexander slaughter the entire population of Massaga, but also did he reduce its buildings to rubble". A similar slaughter followed at Ora. In the aftermath of Massaga and Ora, numerous Assakenians fled to the fortress of Aornos. Alexander followed close behind and captured the strategic hill-fort after four bloody days. After reading the above, is "To come to him and submit to his authority, Ambhi Kumar, the ruler of Persia" the correct answer to the question "What were the reasons for Alexander's invitation and who obliged?"? OPTIONS:
- no
- yes

Answer:
no

Input: If you build a campfire, you start with a large stack of sticks and logs. As the fire burns, the stack slowly shrinks. By the end of the evening, all that is left is a small pile of ashes. What happened to the matter that you started with? Was it destroyed by the flames? It may seem that way. What do you think happened? The truth is that the same amount of matter still exists. The wood changed not only to ashes, but also to carbon dioxide, water vapor, and other gases. The gases floated off into the air, leaving behind just the ashes. Although matter was changed, it was not created or destroyed. Because the same amount of matter still exists, we can say that matter is conserved. You may wonder how it can be conserved if something is now missing? Assume you had measured the mass of the wood before you burned it. Assume you had also trapped the gases released by the burning wood and measured their mass and the mass of the ashes. What would you find? The ashes and gases combined have the same mass as the wood you started with. This example illustrates the law of conservation of mass.
"Is any matter destroyed when you burn wood in a campfire?" is "It evaporates into nothingness"?

OPTIONS:
- no
- yes
Output:
no
