Input: Dam Good Luck: From the beginning, Las Vegas was built to serve travelers. The railroad needed a way station, and Las Vegas was the place. Growth continued for ten years, and by 1915 the town had telephones, round-the-clock electricity, and a growing populationmany of whom worked in the railroad repair shop. But such heady progress would soon come to a halt. The growing competition in rail transport resulted in Union Pacific buying the Los AngelesSalt Lake line. Union Pacific then consolidated its operations, eliminating the Las Vegas repair facility. Additionally, Las Vegas had been made a part of Nevada's new Clark County in 1909, a year when the legislature also outlawed gambling. These unfortunate circumstances threatened to relegate Las Vegas to the status of a small desert community that could no longer support its 3000 residents. But the southwest's growing need for water, combined with Las Vegas's fortuitous proximity to the Colorado River, would give Las Vegas a second chance to achieve prosperity. Construction on Hoover Dam (originally Boulder Dam, subsequently renamed for the president who authorized the project) began in 1931 in a canyon 45 miles (72 km) southeast of Las Vegas. Providing an influx of $165 million to the southwestern economy, Hoover Dam played a major role in preventing Las Vegas from drying up, both financially and literally. Not only did it create jobs, but it also created Lake Mead, the massive reservoir that today provides water to all of southern Nevada. More Government Help: The construction of Hoover Dam did not single-handedly save Las Vegas, however. The state legislature helped as well, by legalizing gambling in 1931 and thus solidifying the future of the town, though legislators and residents could never have known this at the time. The hordes of people who attended Hoover Dam's 1935 dedication set the city's now-formidable public relations machine into action. They went to work on what has become one of the lengthiest citywide tourism campaigns ever attempted. It didn't take long for the city to establish itself as a wild-West town with an "anything goes" attitude. Vices outlawed or heavily controlled elsewhere were legal here, available any hour of any day (or night).

Does the response "Growing competition and reducing population" correctly answer the question "What circumstances threatened to relegate Las Vegas to the status of a small desert community that could no longer support its 3000 residents?"?

Input: Let me begin again. I like life on the resort worlds -- always have and, after the upcoming mindwipe, always will. Last year, I rented a small house on Vega IV, a sea world, all islands and reefs and archipelagos, turquoise waters and aquamarine skies, sunrises like symphonies and sunsets like stars gone supernova. There's only one city: called Nuevo Acapulco in La Enciclopedia del Empirio de la Humanidad, it's N'apulco to the locals. The N'apulcans are mostly emigrants from Polaris II; the only difference between them and their Carribbean ancestors is that the ancestors fleeced NorAm tourists. Now the N'apulcans profit from their Hispanic siblings. I don't mean to sound cynical. I suppose I wish to show that I'm still capable of a certain authorial distance, a semblance of dispassionate observation. The following events may indicate otherwise. In fine tourist tradition, most homes on Vega IV are named. Mine was The Sleeping Flamingo, and its outer walls were coral pink. Were they mood-sensitive, they would have changed as I first viewed them. The rental agent, an attractive N'apulcan named Tasha Cortez, was not mood-sensitive either. She said, "It's beautiful, isn't it, Senor Flynn?" My instinct was to gesture curtly with a cupped hand that she lift the wind boat and take me elsewhere. But she was young and attractive (as I have said and may say again) and eager and so happy to be assisting the infamous Bernardo Flynn that I merely raised an eyebrow in mild scepticism. And then, because a playwright cannot resist a promising line, I said, "Your Sleeping Flamingo should be put to sleep."

Does the response "Polaris II" correctly answer the question "What is the full name of the city Tasha Cortez came from?"?

Input: Sara wanted to play on a baseball team. She had never tried to swing a bat and hit a baseball before. Her Dad gave her a bat and together they went to the park to practice. Sara wondered if she could hit a ball. She wasn't sure if she would be any good. She really wanted to play on a team and wear a real uniform. She couldn't wait to get to the park and test out her bat. When Sara and her Dad reached the park, Sara grabbed the bat and stood a few steps away from her Dad. Sara waited as her Dad pitched the ball to her. Her heart was beating fast. She missed the first few pitches. She felt like quitting but kept trying. Soon she was hitting the ball very far. She was very happy and she couldn't wait to sign up for a real team. Her Dad was very proud of her for not giving up.

Does the response "Signing up for a real team" correctly answer the question "Why was Sara's dad proud of her for not giving up?"?

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 "No, she was his mistress" correctly answer the question "Did Alexander marry the mother of Heracles of Macedon?"?
