instruction:
In this task, you're expected to write answers to questions involving multiple references to the same entity. The answer to the question should be unambiguous and a phrase in the paragraph. Most questions can have only one correct answer.
question:
Passage: After the Southwest became part of the U.S., explorers continued to look for good east–west routes along the 35th parallel. In 1853, a crew led by U.S. Army Lieutenant Amiel Whipple surveyed along a sandy wash in the northern part of the Petrified Forest. So impressed was Whipple by the petrified wood along the banks of the arroyo that he named it Lithodendron Creek (Stone Tree Creek). Geologist Jules Marcou, a member of the Whipple expedition, observed that the petrified trees were from the Triassic.A slightly later route along the parallel was a wagon road, built between 1857 and 1860, that involved experimental use of camels as transport. In the late 19th century, settlers and private stagecoach companies followed similar east–west routes. Homesteaders who stayed in the area developed cattle ranches on the grasslands, and cattle grazed in the Petrified Forest until the mid-20th century.Also close to the 35th parallel was the Atlantic and Pacific Railroad. Its opening in the early 1880s led to the founding of towns like Holbrook and Adamana. Visitors could stop at the Adamana train station, book a hotel room, and take a tour of what was then called the Chalcedony Forest. Over the years, the line changed hands, becoming the Atchison, Topeka and Santa Fe Railway, and then the BNSF. More than 60 BNSF trains, mostly carrying freight, pass through the park every day. U.S. Route 66, a former transcontinental auto highway developed in 1926 from part of the National Old Trails Road, ran parallel to the railroad tracks until it was decommissioned in 1985. The park has preserved within its boundaries a small grassy section of the road. Interstate 40, which crosses the park, replaced the older highway. 
Question: What town could you take a tour of the Chalcedony Forest from?
answer:
Adamana.


question:
Passage: Marojejy National Park is a national park in the Sava Region of northeastern Madagascar. It covers 55,500 ha (214 sq mi) and is centered on the Marojejy Massif, a mountain chain that rises to an elevation of 2,132 m (6,995 ft).  Access to the area around the massif was restricted to research scientists when the site was set aside as a strict nature reserve in 1952.  In 1998, it was opened to the public when it was converted into a national park.  It became part of the World Heritage Site known as the Rainforests of the Atsinanana in 2007.  Despite its rugged terrain, poaching and selective logging are still persistent problems, particularly since the start of the 2009 political crisis in Madagascar.  Mining, slash-and-burn agriculture, and wood collection also pose threats to the park and its wildlife.
The wide range of elevations and rugged topography of the massif create diverse habitats that transition quickly with changes in altitude.  Warm, dense rainforest can be found at lower elevations, followed by shorter forests at higher elevations, followed still by cloud forest, and topped near the peaks with the only remaining undisturbed mountain scrub in Madagascar.  Better growing conditions for plants can be found on the eastern side of the mountains, which receives more rain than the western side.  This habitat diversity lends itself to high levels of biodiversity.  At least 118 species of bird, 148 species of reptile and amphibian, and 11 species of lemur are known to occur within Marojejy National Park.  One of the lemurs, the silky sifaka (Propithecus candidus) is listed among "The World's 25 Most Endangered Primates".  The helmet vanga (Euryceros prevostii) is considered the iconic bird species of the park.
One path leads from the entrance of the park to the summit.  There are three camps along the route: Camp Mantella at 450 m (1,480 ft) in elevation in lowland rainforest, Camp Marojejia at 775 m (2,543 ft) at the transition between lowland and montane rain forest, and Camp Simpona at 1,250 m (4,100 ft) in the middle of the montane rainforest.  Camp Simpona acts as a base camp for the trek to the summit, a route that stretches 2 km (1.2 mi) and can take up to four or five hours to traverse. 
Question: How many km is the route that stretches to the summit in the park that is centered on the Marojejy Massif?
answer:
2.


question:
Passage: See also: FP (Catalogue of compositions), List of compositionsPoulenc's music is essentially diatonic. In Henri Hell's view, this is because the main feature of Poulenc's musical art is his melodic gift. In the words of Roger Nichols in the Grove dictionary, "For [Poulenc] the most important element of all was melody and he found his way to a vast treasury of undiscovered tunes within an area that had, according to the most up-to-date musical maps, been surveyed, worked and exhausted." The commentator George Keck writes, "His melodies are simple, pleasing, easily remembered, and most often emotionally expressive."Poulenc said that he was not inventive in his harmonic language. The composer Lennox Berkeley wrote of him, "All through his life, he was content to use conventional harmony, but his use of it was so individual, so immediately recognizable as his own, that it gave his music freshness and validity."  Keck considers Poulenc's harmonic language "as beautiful, interesting and personal as his melodic writing ... clear, simple harmonies moving in obviously defined tonal areas with chromaticism that is rarely more than passing". Poulenc had no time for musical theories; in one of his many radio interviews he called for "a truce to composing by theory, doctrine, rule!" He was dismissive of what he saw as the dogmatism of latter-day adherents to dodecaphony, led by René Leibowitz, and greatly regretted that the adoption of a theoretical approach had affected the music of Olivier Messiaen, of whom he had earlier had high hopes. To Hell, almost all Poulenc's music is "directly or indirectly inspired by the purely melodic associations of the human voice". Poulenc was a painstaking craftsman, though a myth grew up – "la légende de facilité" – that his music came easily to him; he commented, "The myth is excusable, since I do everything to conceal my efforts."The pianist Pascal Rogé commented in 1999 that both sides of Poulenc's musical nature were equally important: "You must accept him as a whole. If you take away either part, the serious or the non-serious, you destroy him. If one part is erased you get only a pale photocopy of what he really is." Poulenc recognised the dichotomy, but in all his works he wanted music that was "healthy, clear and robust – music as frankly French as Stravinsky's is Slav". 
Question: What is the name of the person whose use of conventional harmony was so individual, and so immediately recognizable as his own, that it gave his music freshness and validity?
answer:

Poulenc.
