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.

Input: Consider Input: 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 consent—no 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.

Output: What were entrusted to take children to school?


Input: Consider Input: Passage: Martin recalled that Sgt. Pepper "grew naturally out of Revolver", marking "an era of almost continuous technological experimentation". According to Geoff Emerick, the Beatles' recording engineer, the "major difference" between the two albums was that, with Sgt. Pepper, there was no absolute deadline for completion. Sessions began on 24 November 1966 in Studio Two at EMI Studios (subsequently Abbey Road Studios), marking the first time that the Beatles had come together since September. Afforded the luxury of a nearly limitless recording budget, the band booked open-ended sessions that started at 7 pm and allowed them to work as late as they wanted. They began with "Strawberry Fields Forever", followed by two other songs that were thematically linked to their childhoods: "When I'm Sixty-Four", the first session for which took place on 6 December, and "Penny Lane". "Strawberry Fields Forever" made prominent use of Mellotron, a keyboard instrument on which the keys triggered tape-recordings of a variety of instruments, enabling its user to play keyboard parts using those voices."Strawberry Fields Forever" and "Penny Lane" were subsequently released as a double A-side in February 1967 after EMI and Epstein pressured Martin for a single. When it failed to reach number one in the UK, British press agencies speculated that the group's run of success might have ended, with headlines such as "Beatles Fail to Reach the Top", "First Time in Four Years" and "Has the Bubble Burst?" In keeping with the band's approach to their previously issued singles, the songs were then excluded from Sgt. Pepper. Martin later described the decision to drop these two songs as "the biggest mistake of my professional life". In his judgment, "Strawberry Fields Forever", which he and the band spent an unprecedented 55 hours of studio time recording, "set the agenda for the whole album". He explained: "It was going to be a record ... [with songs that] couldn't be performed live: they were designed to be studio productions and that was the difference." McCartney declared: "Now our performance is that record.".

Output: What is the name of the band that began Sgt. Pepper with "Strawberry Fields Forever," followed by two other songs that were thematically linked to their childhoods?


Input: Consider Input: Passage: In Yorkshire, England, at the estate of the Duke of Rudling, the British Army converted the grounds into a training camp for war dogs. The camp is placed under the supervision of Sam Carraclough, the kennel caretaker, who immediately begins the process of selecting the best dogs for training, including Laddie, the young pup of the champion collie, Lassie. Joe Carraclough, now an adult, joins the Royal Air Force during the Second World War. Departing for training school, he is forced to leave behind his dog Lassie and her pup, Laddie.
Laddie, being considered as a "war dog", follows Joe to training school and then stows away on his master's bomber, just as it takes off on a dangerous mission over Nazi-occupied Norway. The two are forced to parachute when hit by enemy fire. Laddie then seeks help for his injured master. While they are separated, Joe is captured, and the dog is pursued by enemy soldiers. Laddie is sheltered, first by young Norwegian children who find him, and later by a freedom-fighter who is killed. Laddie finally reaches the prisoner-of-war camp where his master had been taken.
The German guards use Laddie to seek out his master who had escaped. In his search for Joe, who is forced into a labor detail on a coastal gun emplacement, Laddie is reunited with his master and thereafter the two race for their lives to reach friendly lines as the Nazis pursue them. Finally free, both Joe and Laddie make their way back to the Rudling estate to reunite with Lassie, Sam Carraclough, Joe's father and Priscilla, the Duke of Rudling's granddaughter.


Output: What is the full name of the person that Laddie searches for help for?
