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: Sitting in deckchairs and touring churches is not the holiday 17-year-old Richard wants, but his parents insist on taking him. They are staying at the Tregarron guesthouse in the (fictional) seaside town of Easton in Suffolk. This traditional English boarding house is owned and run by the formidable  Miss Wilbraham.   
On arrival, Richard befriends Edwin, who is girl-crazy and takes Richard under his wing. In search of girls, Richard and Edwin attend a beach service organized by the local church  youth group. After the type of evening one might expect at such a gathering, they enjoy a brief tryst with the twin daughters of the minister. 
The following evening another visitor, Julia, agrees to a date with Edwin but only on condition that Anna, her Dutch foreign exchange student friend, can join them. Edwin persuades Richard to join them to make up a foursome. Escaping from his parents on the pretence that the quartet is heading to the youth group's Sausage Sizzle, Richard and his friends visit a local jazz club instead. 
Anna attempts to sneak away with some local bikers and Richard gives chase. As Anna rides away on the back of one biker's machine, Richard jumps on the other. The bikes race off into the sand dunes; where Richard and Anna fall off the pillions and into each other's arms. Richard is annoyed but Anna finds the whole affair amusing. Reaching for a handkerchief to clean a cut on his head, Richard also pulls out a condom that he has taken from Edwin's room.
Julia and Edwin, meanwhile, have been to fetch help. Julia's father, Richard's parents and the minister from the youth group set off to rescue Richard and Anna. A lady walking her dog along the beach stumbles across Richard and Anna as it becomes clear that Richard has experienced sexual initiation. The parents and the minister round the corner just in time to catch the teenagers in flagrante delicto.
Both families make excuses to end their holidays early and head for home.

Output: What are the first names of the foursome that are going out together?


Input: Consider Input: Passage: The St. Johns River (Spanish: Río San Juan) is the longest river in the U.S. state of Florida and its most significant one for commercial and recreational use. At 310 miles (500 km) long, it flows north and winds through or borders twelve counties. The drop in elevation from headwaters to mouth is less than 30 feet (9 m); like most Florida waterways, the St. Johns has a very low flow rate 0.3 mph (0.13 m/s) and is often described as "lazy". Numerous lakes are formed by the river or flow into it, but as a river its widest point is nearly 3 miles (5 km) across. The narrowest point is in the headwaters, an unnavigable marsh in Indian River County. The St. Johns drainage basin of 8,840 square miles (22,900 km2) includes some of Florida's major wetlands. It is separated into three major basins and two associated watersheds for Lake George and the Ocklawaha River, all managed by the St. Johns River Water Management District.
A variety of people have lived on or near the St. Johns, including Paleo-indians, Archaic people, Timucua, Mocama, French and Spanish settlers, Seminoles, slaves and freemen, Florida crackers, land developers, tourists and retirees. It has been the subject of William Bartram's journals, Marjorie Kinnan Rawlings' books, and Harriet Beecher Stowe's letters home. Although Florida was the location of the first permanent European settlement in what would become the United States, it was the last U.S. territory on the east coast to be developed; it remained an undeveloped frontier into the 20th century. When attention was turned to the state, however, much of the land was rapidly overdeveloped in a national zeal for progress. The St. Johns, like many Florida rivers, was altered to make way for agricultural and residential centers. It suffered severe pollution and human interference that has diminished the natural order of life in and around the river. In all, 3.5 million people live within the various watersheds that feed into the St. Johns River. The St. Johns, named one of 14 American Heritage Rivers in 1998, was number 6 on a list of America's Ten Most Endangered Rivers in 2008. Restoration efforts are under way for the basins around the St. Johns as Florida continues to deal with population increases in the river's vicinity.

Output: What state remained an undeveloped frontier into the 20th century?


Input: Consider Input: Passage: Audrey Alston encouraged Britten to go to symphony concerts in Norwich. At one of these, during the triennial Norfolk and Norwich Festival in October 1924,  he heard Frank Bridge's orchestral poem The Sea, conducted by the composer. It was the first substantial piece of modern music he had ever encountered, and he was, in his own phrase, "knocked sideways" by it. Audrey Alston was a friend of Bridge; when he returned to Norwich for the next festival in 1927 she brought her not quite 14-year-old pupil to meet him. Bridge was impressed with the boy, and after they had gone through some of Britten's compositions together he invited him to come to London to take lessons from him. Robert Britten, supported by Thomas Sewell, doubted the wisdom of pursuing a composing career; a compromise was agreed by which Britten would, as planned, go on to his public school the following year but would make regular day-trips to London to study composition with Bridge and piano with his colleague Harold Samuel.Bridge impressed on Britten the importance of scrupulous attention to the technical craft of composing and the maxim that "you should find yourself and be true to what you found." The earliest substantial works Britten composed while studying with Bridge are the String Quartet in F, completed in April 1928, and the Quatre Chansons Françaises, a song-cycle for high voice and orchestra. Authorities differ on the extent of Bridge's influence on his pupil's technique. Humphrey Carpenter and Michael Oliver judge that Britten's abilities as an orchestrator were essentially self-taught; Donald Mitchell considers that Bridge had an important influence on the cycle.


Output: What is the first name of the person Alston encouraged to go to symphony concerts?
