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.

Input: Consider Input: 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 is the name of the place that 60 BNSF trains pass through everyday?

Output: Petrified Forest.


Input: Consider Input: Passage: When two grade-school boys get into a fight in the park that results in one boy, Zachary Cowan, hitting the other, Ethan Longstreet, in the face with a stick, their parents meet in a Brooklyn apartment to discuss the matter. Zachary's parents, Alan and Nancy Cowan, visit the home of Michael and Penelope Longstreet, Ethan's parents. Their meeting is initially intended to be short, but due to various circumstances, the conversation continues to draw out.
In fact, Alan and Nancy begin to leave the apartment on two occasions, but are drawn back in to further discussion.
At first, the couples are friendly to each other, but their respective comments start to hurt feelings, making everyone argue with one another. Apart from fighting among themselves, the couples blame each other about who is responsible for the fight between their sons. Nancy calls the Longstreets "superficially fair-minded" and Penelope and Michael complain about Alan's arrogant and dull attitude. Everyone also gets irritated with Alan when he accepts endless business phone calls on his BlackBerry, interrupting the discussion, and showing he has more interest in his business problems than the matter at hand. Michael also receives many phone calls from his ailing mother, to his frustration.
Nancy accuses Michael of being a murderer because he, annoyed by the constant noise it made during the night, had earlier turned his daughter Courtney's pet hamster loose in the street. Penelope becomes emotional about the hamster and with everyone arguing with each other. Other issues include a risky drug Alan is working to defend and Michael's mother has been prescribed, and the question of idealism and responsibility that is part of Penelope's current work. 
Question: Who is Courtney's father?

Output: Michael.


Input: Consider Input: Passage: During the latter half of 2002, Sasha collaborated with big beat artist Junkie XL on the single "Breezer". Junkie XL, along with Charlie May, also assisted Sasha on his second album of original material, Airdrawndagger.  Airdrawndagger took several years to produce due to Sasha's desire for the album to be "as near to perfection as possible."  That March, Sasha suffered a perforated eardrum in a traffic accident, further delaying the album's production. Though the accident temporarily impaired his hearing, he drew inspiration for the album from his ordeal.  Airdrawndagger was finally released, in August 2002, to much fanfare. However, the album was "received with a lot of head scratching", according to Sasha, which he attributed to its unexpected mix of genres. The album did not feature the heavier "club sound" of Sasha's previous mix albums, bearing a closer resemblance to ambient music.  Airdrawndagger generally received favorable reviews, though critics noted that it was not as consistent and well produced as his DJ mixes. Sasha himself described it as "a selfish, slightly self-indulgent record", though he maintains that he is "happy with it to this day".  Some critics, however, called it "sleepy"; E!Online described it as being "more in league with Yanni than Moby".  To encourage listeners' interest, Sasha held an amateur remix contest for the album's single, "Wavy Gravy".  Due to the contest's success, Sasha released all the tracks from Airdrawndagger on his website, so that fans could download and create their own versions.After the release of Airdrawndagger, Sasha took the young DJ James Zabiela "under his wing". He introduced Zabiela to the CDJ1000 turntable, and signed Zabiela to the Excession talent agency.  The two toured the United States together, which extended Sasha's influence to already-popular American DJs such as Kimball Collins.
In 2004, Sasha signed with Global Underground to produce another mix album. However, he found the process of creating a standard mix album unrewarding, and decided to apply his production and DJing skills to a mix compilation that resembled a "real" album—that is, one featuring original material.  Sasha's next studio album, Involver, was "a fusion of mix album and production record", consisting entirely of Sasha's reworkings of tracks by other artists.  "I tried to take all the separate sounds to all the tracks [and recombine them]", he later explained, "and it allowed me to mix the tracks together on a much deeper level."  He accomplished this by sequencing the album using Ableton Live and Logic Pro.  Ableton Live is a music loop-based software package that Sasha uses to engineer tracks in real-time, whereas he used Logic Pro primarily for premeditated edits to audio tracks. 
Question: Whose album was "received with a lot of head scratching?"?


Output: Sasha.
