Example 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. <sep>Why did Hephaestion's death devastate Alexander?<sep>He was close with him and they were friends
Example Output: Yes

Example Input: The inhabited history of the Las Vegas Valley stretches to 23,000 b.c. , when much of the area was covered by a prehistoric lake. During this period, the indigenous people lived in caves, hunting the mammals that gathered at the shoreline. The landscape of the valley changed dramatically over the next 200 centuries. The glaciers feeding the lake melted away and the lake evaporated. Fossils tell an obscure story of man's slow and sporadic development. Around 3000 b.c. , native Archaic Indians began to develop a lasting hunting and gathering culture. By this time, the valley was in much the same geographic state as it exists in today, with one exception — the presence of artesian springs that bubbled to the surface in several areas. These springs fed a network of streams draining through the Las Vegas Wash to the Colorado River. The areas surrounding the springs were desert oases: sprawling collections of grasses, trees, and wildlife. Many springs lay in areas that would eventually become the center of the modern Las Vegas metropolis. For about 4000 years, the Archaics thrived in a culture that included many signs of early civilization. Signs of even more advancement appeared halfway through the first millennium a.d. , when the Anasazi Indians inhabited the valley. Far more progressive than the Archaics, the Anasazi utilized such formal agricultural techniques as irrigation to assist their harvest. This permitted the Anasazi to achieve a benchmark of advanced society — the ability to live in permanent shelters year-round without need to follow wildlife. Mysteriously, the Anasazi vanished from the valley around a.d. <sep>Why did the prehistoric lake disappear from the Las Vegas Valley?<sep>Deforestation
Example Output: No

Example Input: If you beat a dog in Schuylkill County, you'll probably get a $100 fine. If you repeatedly beat a woman, you'll probably get the same fine. In 2001, county judges heard 98 Protection From Abuse cases, finding the defendant guilty in 48 percent of those cases, either after a hearing or through a technical violation or plea. Of those found guilty, the majority were ordered to pay court costs, plus a $100 fine. No defendants were ordered to pay more than a $250 fine for violating the court order. In 27 percent of the cases, the charges were dismissed or the defendant was found not guilty. In the rest of the cases, charges were withdrawn or the matter is not yet resolved. Sarah T. Casey, executive director of Schuylkill Women in Crisis, finds it disturbing that in most cases, the fine for violating a PFA is little more than the fine someone would get for cruelty and abuse toward an animal. "In most of the counties surrounding Schuylkill County, the penalties given for indirect criminal contempt are much stiffer than those in Schuylkill County," Casey said. "What kind of message are we sending those who repeatedly violate Protection From Abuse orders? That it's OK to abuse women in Schuylkill County, because you'll only get a slap on the wrist?" Under state law, the minimum fine for contempt of a PFA is $100; the maximum fine is $1,000 and up to six months in jail. Like others who are familiar with how the county's legal system does and doesn't work for victims of domestic violence, Casey believes some changes are in order. Valerie West, a manager/attorney with Mid-Penn Legal Services, with offices in Pottsville and Reading, regularly handles domestic violence cases. She finds fault with the local requirement that a custody order must be established within 30 days after a PFA is filed. West said she feels a custody order should be allowed to stand for the full term of the PFA - up to 18 months - as it does in many other counties in the state. "It places an undue burden on the plaintiff, in terms of cost, finding legal representation and facing their abuser - not to mention a further burden on the system to provide those services," West said. "It may be difficult for the parties to reach an agreement so soon after violence has occurred. <sep>What kind of fine do you get for repeatedly beating a woman?<sep>100 dollars
