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.

Example Input: Passage: Geologically, Portland is separated into two areas; the steeply sloping land at its north end called Underhill, and the larger, gently sloping land to the south, called Tophill. Portland stone lies under Tophill; the strata decline at a shallow angle of around 1.5 degrees, from a height of 151 metres (495 ft) near the Verne in the north, to just above sea level at Portland Bill. The geology of Underhill is different to Tophill; Underhill lies on a steep escarpment composed of Portland Sand, lying above a thicker layer of Kimmeridge Clay, which extends to Chesil Beach and Portland Harbour. This Kimmeridge Clay has resulted in a series of landslides, forming West Weares and East Weares.2.4 kilometres (1.5 mi) underneath south Dorset lies a layer of Triassic rock salt, and Portland is one of four locations in the United Kingdom where the salt is thick enough to create stable cavities. Portland Gas applied to excavate 14 caverns to store 1,000,000,000 cubic metres (3.51010 cu ft) of natural gas, which is one percent of the UK's total annual demand. It was proposed that the caverns should be connected to the National gas grid at Mappowder via a 37-kilometre (23 mi) pipeline. Plans had it that the surface facilities should be complete to store the first gas in 2011, and the entire cavern space available for storage in winter 2013. As part of the 350 million scheme, the Grade II listed former Old Engine Shed would be converted into a 1.5 million educational centre with a cafe and an exhibition space about the geology of Portland.
Example Output: What is the full name of the acronym UK?

Example Input: Passage: Dr. Watson is serving as resident doctor at Musgrave Manor in Northumberland, a stately home which is also used as a hospital for a number of servicemen suffering from shell shock.When Sally Musgrave displays her feelings for one of the wounded American fighter pilots, Captain Pat Vickery, who is currently recovering at the family estate, her brothers Geoffrey and Phillip are quick to show their dismay.
Then one of the physicians working at the estate, Dr. Sexton, is assaulted by an unknown assailant when out on a walk. Dr. John Watson, who is in charge of the medical facility, goes to fetch his dear friend Sherlock Holmes to bring some clarity to the case of the attack.
Upon his arrival to the estate, Sherlock Holmes discovers the dead body of one of the brothers, Geoffrey. Inspector Lestrade of the Scotland Yard is put on the case to solve the murder, and immediately arrests the captain as a suspect.
Holmes is of another opinion about the flyer's guilt and continues to investigate on his own. Phillip is formally made the new head of the estate the next day with the aid of his sister. But after only one day of ruling the estate, Phillip too is found murdered, lying in the trunk of the car.
Lestrade suspects the family butler, Alfred Brunton, to be the murderer because Phillip had just fired the butler. Trying to arrest the butler, Lestrade gets lost in the manor's secret passageways. Meanwhile Holmes and Watson look into the special "Musgrave Ritual" that the family uses to appoint the new head of the family. They find the words used in the ritual hidden in Sally's room and try to copy the ritual, which involves replaying a giant chess game on the checkered floor of the house main hall. As pieces in the game they use the household staff.
Example Output: Who fired the butler before the crimes were committed?

Example Input: Passage: Before he entered the third grade, Peter Gwazdauskas was originally in a separate school for students with disabilities. When he entered the third grade, he enrolled in a traditional school due to a change in federal law stating that students with disabilities should be educated with typically developing students in general education. Even though Peter had improved since third grade, he still had some social issues, including suffering through depression and having occasional behavioral outbursts. During the school day, Peter was accompanied by paraprofessionals to help him stay directed and learning. Sometimes during class, he was pulled out of the lesson in order to work with a paraprofessional in a one-on-one setting. To increase his social skills, Peter had some community-based jobs during the time he was in middle school and high school. In the summer, he had a summer aide in order to continue his functional education, learning vocational skills and community-based living practices. Peter also participated in extracurricular activities at his school, like being in the concert band as well as being the manager of the soccer team. He was also in a school club with both typically developing peers and peers with disabilities. Since joining, it has helped Peter improve his social skills. He improved even more in social and vocational skills by the end of his senior year of high school and went on to graduate with his classmates.
Example Output:
When did Peter join a class of normal children?
