Problem: Earth processes have not changed over time. The way things happen now is the same way things happened in the past. Mountains grow and mountains slowly wear away. The same process is at work the same as it was billions of years ago. As the environment changes, living creatures adapt. They change over time. Some organisms may not be able to adapt. They become extinct. Becoming extinct means they die out completely. Some geologists study the history of the Earth. They want to learn about Earths past. They use clues from rocks and fossils. They use these clues to make sense of events. The goal is to place things in the order they happened. They also want to know how long it took for those events to happen.

Question: "If Earths processes do not change, what does?"

Answer: "Environment"

OPTIONS:
- no
- yes
Answer: yes

Problem: 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.

Question: "Why did Hephaestion's death devastate Alexander?"

Answer: "Alexander also had a close relationship with his friend, general, and bodyguard Hephaestion"

Problem: As for the Italians, we know that Paesiello, who was a famous intriguer against his musical rivals, was a devoted husband whose wife was an invalid and who died soon after her death. Cherubini married Mademoiselle Cecile Turette, when he was thirty-five, and the marriage was not a success. He left a son and two daughters. Spontini, one of whose best operas was based on the life of that much mis-married enthusiast for divorce, John Milton, took to wife a member of the Erard family. In the outer world Spontini was famous for his despotism, his jealousy, his bad temper, and his excessive vanity. None of these qualities as a rule add much to home comfort, and yet, it is said that he lived happily with his wife. We may feel sure that some of the bad light thrown on his character is due purely to the jealousy of rivals, when we consider his domestic content, his ardent interest in the welfare of Mozart's widow and children, and the great efforts he made to secure subscriptions for the widow's biography of Mozart.

Question: "Who left a son and two daughters?"

Answer: "Mozart"
