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.

[EX Q]: 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: What is the name of the person whose hearing was temporarily impaired?
[EX A]: Sasha.

[EX Q]: Passage: There is considerable uncertainty about the identities of the Grand Dukes of Lithuania between Traidenis' death in 1282 and Vytenis' assumption of power in 1295. This is in part because the two main sources for Lithuanian history in the 13th century, the Hypatian Codex and the Livonian Rhymed Chronicle, end in the early 1290s. In 1285, one chronicle mentions Daumantas as Grand Duke. He attacked the Bishop of Tver and was severely wounded or even killed in the battle. However, that is the only information about him.
The Gediminid dynasty began its ascent in Lithuania during this time with the emergence of its first leader, Butigeidis. In 1289, leading about 8,000 troops, he attacked Sambia. In 1289 the Teutonic Knights built a castle in present-day Sovetsk (Tilsit) and their raids intensified. Butigeidis was the first to build strong castles along the Neman River. He died in 1290 or 1292, and his brother Butvydas (also known as Pukuveras) inherited the crown. Butvydas was the father of Vytenis and probably of Gediminas. During his short reign Butvydas tried to defend the duchy against the Teutonic Knights; he also attacked Masovia, an ally of the knights. His son, Vytenis, advanced to power in 1295 and ended the period of relative instability. His reign marks the transition from the state's establishment to the point at which it was poised for expansion. 
Question: What is the alias of the person that inherited the crown from Butigeidis?
[EX A]: Pukuveras.

[EX Q]: Passage: Because of the 1932 Byrd Road Act, the state government controls most of Virginia's roads, instead of a local county authority as is usual in other states. As of 2018, the Virginia Department of Transportation owns and operates 57,867 miles (93,128 km) of the total 70,105 miles (112,823 km) of roads in the state, making it the third largest state highway system in the United States. Although the Washington Metropolitan Area, which includes Northern Virginia, has the second highest rate of traffic congestion in the nation, Virginia as a whole has the 21st-lowest rate of congestion and the average commute time is 26.9 minutes. Virginia hit peak car usage before the year 2000, making it one of the first such states.
Virginia has Amtrak passenger rail service along several corridors, and Virginia Railway Express (VRE) maintains two commuter lines into Washington, D.C. from Fredericksburg and Manassas. VRE is one of the nation's fastest growing commuter rail services, handling nearly 20,000 passengers a day. Arlington accounted for 40% of Virginia's public transit trips as of 2013, with most of that being from the Washington Metro transit system, which also serves Alexandria  and communities in Fairfax County along I-66. The system is currently expanding west into additional areas of Loudoun County. Major freight railroads in Virginia include Norfolk Southern and CSX Transportation, the former of which is headquartered in Norfolk. Commuter buses include the Fairfax Connector and the Shenandoah Valley Commuter Bus. The Virginia Department of Transportation operates several free ferries throughout Virginia, the most notable being the Jamestown-Scotland ferry which crosses the James River in Surry County.Virginia has five major airports: Washington Dulles International and Reagan Washington National in Northern Virginia, both of which handle over 20 million passengers a year; Richmond International; and Newport News/Williamsburg International Airport and Norfolk International serving the Hampton Roads area. Several other airports offer limited commercial passenger service, and sixty-six public airports serve the state's aviation needs. The Virginia Port Authority's main seaports are those in Hampton Roads, which carried 17,726,251 short tons (16,080,984 t) of bulk cargo in 2007, the sixth most of United States ports. The Eastern Shore of Virginia is the site of Wallops Flight Facility, a rocket testing center owned by NASA, and the Mid-Atlantic Regional Spaceport, a commercial spaceport. Space tourism is also offered through Vienna-based Space Adventures. 
Question: What is the name of the rocket testing center in the state with Norfolk Southern?
[EX A]:
Wallops Flight Facility.
