Input: Renewable Energy Resource Sunlight Sunlight can be used to heat homes. It can also be used to produce electricity. This conversion is made possible by solar cells. However, solar energy may not always be practical. Some areas are just too cloudy. Example Solar panels on the roof of this house generate enough electricity to supply a familys needs. Moving Water Falling water can have a lot of energy. Its energy can be converted into kinetic energy. This energy can turn a turbine and generate electricity. The water may fall naturally over a waterfall or flow through a dam. A drawback of dams is that they flood land upstream. They can also reduce water flow downstream. Either effect may harm ecosystems. Wind Wind is moving air. It has kinetic energy that can do work. Wind turbines change the kinetic energy of the wind to electrical energy. Only certain areas of the world get enough steady wind. Many people also think that wind turbines are noisy and not very nice to look at.
"What are some ways sunlight can be used?" is "Solar energy"?

Input: Alexander married twice: Roxana, daughter of the Bactrian nobleman Oxyartes, out of love; and Stateira II, a Persian princess and daughter of Darius III of Persia, for political reasons. He apparently had two sons, Alexander IV of Macedon of Roxana and, possibly, Heracles of Macedon from his mistress Barsine. He lost another child when Roxana miscarried at Babylon. Alexander also had a close relationship with his friend, general, and bodyguard Hephaestion, the son of a Macedonian noble. Hephaestion's death devastated Alexander. This event may have contributed to Alexander's failing health and detached mental state during his final months. Alexander's sexuality has been the subject of speculation and controversy. No ancient sources stated that Alexander had homosexual relationships, or that Alexander's relationship with Hephaestion was sexual. Aelian, however, writes of Alexander's visit to Troy where "Alexander garlanded the tomb of Achilles and Hephaestion that of Patroclus, the latter riddling that he was a beloved of Alexander, in just the same way as Patroclus was of Achilles". Noting that the word eromenos (ancient Greek for beloved) does not necessarily bear sexual meaning, Alexander may have been bisexual, which in his time was not controversial. Green argues that there is little evidence in ancient sources that Alexander had much carnal interest in women; he did not produce an heir until the very end of his life. However, he was relatively young when he died, and Ogden suggests that Alexander's matrimonial record is more impressive than his father's at the same age. Apart from wives, Alexander had many more female companions. Alexander accumulated a harem in the style of Persian kings, but he used it rather sparingly; showing great self-control in "pleasures of the body". Nevertheless, Plutarch described how Alexander was infatuated by Roxana while complimenting him on not forcing himself on her. Green suggested that, in the context of the period, Alexander formed quite strong friendships with women, including Ada of Caria, who adopted him, and even Darius's mother Sisygambis, who supposedly died from grief upon hearing of Alexander's death.

Does the response "Once" correctly answer the question "How many time Roxana was pregnant form Alexander?"?

Imagine a glass of your favorite drink that never became empty. Now think about what really happens. You take a drink and there is less in the glass. You keep drinking and soon it is all gone. Good thing you have more to refill your glass. What if there would never be any more of your favorite drink. What would you do? Now you know the difference between renewable and non-renewable. Its too bad that many things here on Earth will run out. This includes some of our natural resources we depend on. Things like oil will not last forever. There is a limited supply. Someday, we will run out, so then what? At current rates of use, coal will last about 300 years. Petroleum will be used up in just a few decades.

Question: "What are some examples of resources that will run out?"

OPTIONS:
- no
- yes

Answer: "Natural gas"

Response: yes

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: "When did Aleksandr Sergeyevich Pushkin die?"
