In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

[Q]: Passage: In 1916, childhood best friends, Bob Wilson and Fred von Bergen, are test pilots working for an American company that builds bombers for the European allies. Since he is German-born and faces prejudice against his heritage, Fred loses his job and, unable to find other employment, decides to return to Germany to fight for his homeland. Although he has no special attachment to the German cause, Bob quits the aviation company and joins his friend in Germany.
On their way to a German airfield, Red Cross nurse Alida Hoffman accidentally runs Bob and Fred off the road, Both men are immediately drawn to Alida, especially Bob although Fred is more shy. After Bob's first unsuccessful mission, Captain Wolters, the squadron's tyrannical leader, expresses his doubt about his loyalty but, desperate for pilots, gives him another chance.
As the United States is drawn into the war, instead of sending him into a crucial air battle, Wolters arrests Bob. Fred, heartbroken that Alida has chosen Bob, quarrels with his friend, calling him a coward. Later, however, Fred allows his friend to escape from a firing squad and flee to the Allied lines.
To prove his allegiance, Bob leads British bombers to the German base, while Fred is told by Wolters that he must shoot down Bob to prove his loyalty. Neither man is capable of killing the other, and, in the end, Fred sacrifices his life for Bob. After the war, Bob returns to Germany to marry Alida. The newly married couple then returns to the United States, and pay their respects to Fred's mother.
[A]: What is the first name of the man that is fired for being German-born?

[Q]: Passage: Curiously, it appears that the Greeks did not "breed" their slaves, at least during the Classical Era, though the proportion of houseborn slaves appears to have been rather large in Ptolemaic Egypt and in manumission inscriptions at Delphi. Sometimes the cause of this was natural; mines, for instance, were exclusively a male domain. On the other hand, there were many female domestic slaves. The example of African slaves in the American South on the other hand demonstrates that slave populations can multiply.Xenophon advised that male and female slaves should be lodged separately, that "nor children born and bred by our domestics without our knowledge and consentno unimportant matter, since, if the act of rearing children tends to make good servants still more loyally disposed, cohabiting but sharpens ingenuity for mischief in the bad." The explanation is perhaps economic; even a skilled slave was cheap, so it may have been cheaper to purchase a slave than to raise one. Additionally, childbirth placed the slave-mother's life at risk, and the baby was not guaranteed to survive to adulthood.Houseborn slaves (oikogeneis) often constituted a privileged class. They were, for example, entrusted to take the children to school; they were "pedagogues" in the first sense of the term. Some of them were the offspring of the master of the house, but in most cities, notably Athens, a child inherited the status of its mother.
[A]: What were entrusted to take children to school?

[Q]: Passage: Big Butte Creek drains approximately 245 square miles (635 km2) of southern Oregon. Elevations range from 1,562 feet (476.1 m) at the creek's mouth to 9,495 feet (2,894 m) at the summit of Mount McLoughlin, with an average of 3,528 feet (1,075 m). About 56 percent is federally owned by the Bureau of Land Management and the United States Forest Service, 44 percent is privately owned, and a small fraction belongs to the City of Medford.The Big Butte Creek watershed experiences a Mediterranean climate. Temperatures range from 10 F (12 C) in the winter to 100 F (38 C) in the summer. Precipitation averages between 35 and 80 inches (890 and 2,000 mm) annually. Most precipitation occurs between November and March. Nine percent of the watershed's surface runoff is collected from rain, 35 percent from rain on snow, and 56 percent from snow. The watershed contains the largest groundwater source in the entire Rogue River basin; one major outlet is at Big Butte Springs.The watershed is split into two geographic regions: the High Cascades and the Western Cascades, both volcanic in origin. The Western Cascades compose the western two thirds of the watershed. This region is highly eroded, being between 17 and 38 million years old. Its unstable slopes are primarily made of pyroclastic rock. Due to the rock's high ability to absorb moisture, earthflows are common. The High Cascades are much younger, around three to seven million years old. Mount McLoughlin is the most prominent High Cascade volcano in the watershed, last erupting between 20,000 and 15,000 years ago. Basalt and andesite are the most common rock types in this region.Nearby watersheds include Little Butte Creek to the south, small Klamath River tributaries such as Fourmile Creek to the east, the South Fork Rogue River to the east and north, and minor tributaries of the Rogue River including Reese and Indian creeks to the west.

What watershed is split into two geographic regions?
