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: 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.

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

Q: Passage: As the British fleet closed with the opposing combined fleets of France and Spain, Lord Nelson signalled all the necessary battle instructions to his ships. Aware of the momentousness of events to come, Lord Nelson felt that something extra was required. He instructed his signal officer, Lieutenant John Pasco, to signal to the fleet, as quickly as possible, the message "England confides that every man will do his duty." Pasco suggested to Nelson that expects be substituted for confides (i.e. is confident), since the former word was in the signal book, whereas confides would have to be spelt out letter-by-letter. Nelson agreed to the change (even though it produced a less trusting impression):
His Lordship came to me on the poop, and after ordering certain signals to be made, about a quarter to noon, he said, 'Mr. Pasco, I wish to say to the fleet, ENGLAND CONFIDES THAT EVERY MAN WILL DO HIS DUTY' and he added 'You must be quick, for I have one more to make which is for close action.' I replied, 'If your Lordship will permit me to substitute the confides for expects the signal will soon be completed, because the word expects is in the vocabulary, and confides must be spelt,' His Lordship replied, in haste, and with seeming satisfaction, 'That will do, Pasco, make it directly.'
Thus, at around 11:45 a.m. on 21 October 1805, the signal was sent. The exact time the signal was sent is not known (one account puts it as early as 10:30), as the message was repeated throughout the fleet, but Pasco puts it at "about a quarter to noon" and logs from other ships of the line also put it close to this time.

A: Whose ships were signalled all the necessary battle instructions?

Q: Passage: Lloyd's police department became the first in the county to purchase a Segway, in 2007, for the express purpose of patrolling the rail trail. The trail has been occasionally vandalized. Lloyd's Police Chief felt that use of such a vehicle would enable officers to patrol the trail for longer periods of time, and that it could also be used to patrol other areas of the town. Seven officers were expected to use the Segway, which contains an automated external defibrillator, and can go as fast as 12 1⁄2 miles per hour (20.1 km/h).In March 2009, Ulster County received almost $21 million in stimulus funds. The funding included a $3.16 million project to complete the trail between Lloyd and the Poughkeepsie Bridge. Some funding for the architectural and engineering aspects of the project came from the reserve fund created after the town's fiber optic deal. The Rail Trail Association also received a $1,500 grant from a public-benefit corporation, the Hudson River Valley Greenway, to print brochures. Construction for the 1.28-mile (2.06 km) section was underway by that September. In March 2010, a portion of New Paltz Road was closed pending the replacement of a bridge over the trail.The official groundbreaking ceremony took place on May 4, 2010, and the trail was expected to be completed by October. The bridge over Vineyard Avenue was opened to pedestrian traffic on July 16, 2010. The only remaining obstruction was the placement of a bridge carrying Mile Hill Road over the trail, which was expected to be completed in August. The crossing at US 9W had been remedied; the new section let "users to cross either over or under" the highway. To celebrate the opening of the Vineyard Avenue bridge, Route 44–55 throughout Highland (which includes Vineyard Avenue) was shut down for the day. The eastern expansion does not deviate from the original route of the corridor, and officially opened on October 2, 2010.Between June 23 and 24, 2011, parts of the trail were spray-painted with "dozens of [...] words and images". Volunteers who removed some of the graffiti believed that different types of paint were used. Lloyd's highway superintendent noted similar vandalism elsewhere in the town, and Town Supervisor Ray Costantino stated that the incident would cause Lloyd residents to feel a personal connection to the trail and become outraged.Future expansion to the trail includes a 1-mile (1.6 km) extension to the west, to State Route 299. Lloyd has received a $1.93 million state grant to complete the western expansion, which will reach New Paltz by 2012. Both Lloyd and New Paltz have received grants to establish a connection between the Hudson Valley Rail Trail and the Wallkill Valley Rail Trail. There has never been a direct link between the Poughkeepsie Bridge and the Wallkill Valley corridor. Other plans include the development of commercial zones along the trail, and a project to connect the trail to Illinois Mountain.

A:
What is the full name of the rail trail that Lloyd's police department purchased a Segway to patrol?
