instruction:
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.

Passage: An inventory of medium and large mammals in the park confirmed the presence of 30 species in Saguaro National Park between 1999 and 2008. Of these, 21 were found in the Tucson Mountain District and 29 in the Rincon Mountain District. A partial list of the park's mammals includes cougars, coyotes, bobcats, white-tailed deer, mule deer, javelinas, gray foxes, black-tailed jackrabbits, desert cottontails, ring-tailed cats, white-nosed coatis, ground squirrels, and packrats. One endangered mammal, the lesser long-nosed bat, lives part of the year in the park and part of the year in Mexico.The wide range of habitats in the park supports a diverse population of birds including some, such as the vermilion flycatcher and the whiskered screech owl, uncommon elsewhere in the United States. Among the park's 107 bird species are great horned owls, cactus wrens, ravens, kestrels, turkey vultures, roadrunners, woodpeckers, hawks, quails, and hummingbirds, and one threatened species, the Mexican spotted owl.The park's 36 reptile species include desert tortoises, diamondback rattlesnakes (one of the more commonly seen snakes), coral snakes, Gila monsters, short-horned lizards, spiny lizards, and zebra-tailed lizards. Despite the aridity, three amphibian species inhabit the park: the canyon tree frog, the lowland leopard frog, and Couch's spadefoot, which lives in underground burrows, emerging to breed during summer rains. Forest fires, which create erosion-prone burned areas, have destroyed many of the leopard frog's breeding pools, which fill with sediment. The Arizona Game and Fish Department lists the lowland leopard frog as a species of special concern.Urban sprawl, air and water pollution, noise, light pollution, and a range of habitat restricted by human infrastructure put stress on the park's mammals and other animals, but the most serious immediate threat to them is roadkill. About 50,000 vertebrates a year die on the park's roads when they are hit by a vehicle. The Rincon Mountain District has few roads, but Picture Rocks Road, an east–west commuter highway crossing the Tucson Mountain District, is highly dangerous to wildlife. Attempts in 2002 to convert it to a hiking trail failed after the proposal met with stiff public resistance.
answer:
What was attempted to be converted into a hiking trail?


question:
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.
answer:
What state remained an undeveloped frontier into the 20th century?


question:
Passage: 18 year old Johnnie Simpson lives with his father and Aunt Martha, after his mother died when he was three. His dad is strict with Johnnie and is constantly criticizing him. Johnnie has a girlfriend, Betty Palmer, who works as a waitress at the local drive-in. Maurie Weston, the town bully, owns a fancy hot rod and teases Johnny about him not being allowed to have a car. One night at the drive in, Maurie makes a move on Betty, but she rebuffs his advances, and ends up letting Johnnie drive her home in her brother's car. On the way there, Johnnie gets stopped by the police for speeding and driving recklessly. The police drive him home and give his dad a summons to appear in court with his son. His father berates him for his careless behavior, while Aunt Martha suggests that maybe he should spend more time with his son.
Later, Johnnie gets a summer job at a gas station, without telling his dad. The owner of the station is building a hot rod to race and encourages Johnnie to help him with it. After his father finds out about his new job, he demands that he quit and come to work for him in his real estate office. Later that night, Johnnie and Betty are having dinner together when Maurie again tries to make a move on Betty, and Johnnie gets mad and challenges him to a fight. Maurie suggest that they race instead, and although Johnnie doesn't have a car, he agrees to meet him in an hour. Betty refuses to lend him her brother's car again, so Johnnie asks her to take him to a used car lot where he persuades the salesman to let him test drive a hot rod. Johnnie promises to return the car the next morning.
answer:

What is the full name of the person that Betty Palmer rebuffed thier advances?
