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: Louis Salinger, an Interpol detective, and Eleanor Whitman, an Assistant District Attorney from Manhattan, are investigating the International Bank of Business and Credit, which funds activities such as money laundering, terrorism, arms trading, and the destabilization of governments. Salinger's and Whitman's investigation takes them from Berlin to Milan, where the IBBC assassinates Umberto Calvini, an arms manufacturer who is an Italian prime ministerial candidate. The bank's assassin diverts suspicion to a local assassin with political connections, who is promptly killed by a corrupt policeman. Salinger and Whitman get a lead on the second assassin, but the corrupt policeman shows up again and orders them out of the country. At the airport they are able to check the security camera footage for clues on the whereabouts on the bank's assassin, and follow a suspect to New York City.
In New York, Salinger and Whitman are met by two New York Police Department detectives, Iggy Ornelas and Bernie Ward, who have a photograph of the assassin's face when he arrived in New York airport. Salinger, Ornelas, and Ward locate Dr. Isaacson to whose practice the assassin's leg brace has been traced. They find the assassin and follow him to the Solomon R. Guggenheim Museum.
Jonas Skarssen, the chairman of the IBBC, reveals to his senior men White and Wexler that the bank had Calvini killed so that they could deal with his sons to buy missile guidance systems in which the bank has invested. Since the bank knows that Salinger and Whitman are close to finding their assassin, they send a hit team to kill him at a meeting between him and his handler, Wexler. Wexler leaves and is arrested by Ornelas. As Salinger speaks to the assassin, a shootout at the Guggenheim erupts when a number of gunmen attempt to kill them with automatic weapons. They escape, but the assassin is mortally wounded.
Question: What are the first names of the people who locate Dr. Isaacson?
[EX A]: Louis.

[EX Q]: Passage: The first three symphonies, to which Vaughan Williams assigned titles rather than numbers, form a sub-group within the nine, having programmatic elements, absent from the later six.A Sea Symphony (1910), the only one of the series to include a part for full choir, differs from most earlier choral symphonies in that the choir sings in all the movements. The extent to which it is a true symphony has been debated; in a 2013 study, Alain Frogley describes it as a hybrid work, with elements of symphony, oratorio and cantata. Its sheer lengthabout eighty minuteswas unprecedented for an English symphonic work, and within its thoroughly tonal construction it contains harmonic dissonances that pre-echo the early works of Stravinsky which were soon to follow.A London Symphony (19111913) which the composer later observed might more accurately be called a "symphony by a Londoner", is for the most part not overtly pictorial in its presentation of London. Vaughan Williams insisted that it is "self-expressive, and must stand or fall as 'absolute' music". There are some references to the urban soundscape: brief impressions of street music, with the sound of the barrel organ mimicked by the orchestra; the characteristic chant of the lavender-seller; the jingle of hansom cabs; and the chimes of Big Ben played by harp and clarinet. But commentators have heardand the composer never denied or confirmedsome social comment in sinister echoes at the end of the scherzo and an orchestral outburst of pain and despair at the opening of the finale. Schwartz comments that the symphony, in its "unified presentation of widely heterogeneous elements", is "very much like the city itself". Vaughan Williams said in his later years that this was his favourite of the symphonies.The last of the first group is A Pastoral Symphony (1921). The first three movements are for orchestra alone; a wordless solo soprano or tenor voice is added in the finale. Despite the title the symphony draws little on the folk-songs beloved of the composer, and the pastoral landscape evoked is not a tranquil English scene, but the French countryside ravaged by war. Some English musicians who had not fought in the First World War misunderstood the work and heard only the slow tempi and quiet tone, failing to notice the character of a requiem in the music and mistaking the piece for a rustic idyll. Kennedy comments that it was not until after the Second World War that "the spectral 'Last Post' in the second movement and the girl's lamenting voice in the finale" were widely noticed and understood.
Question: What is the title of the symphony that draws little on the folk-songs beloved by the composer?
[EX A]: A Pastoral Symphony.

[EX Q]: Passage: After the demise of the migratory Turkish colony, the northern bald ibis was known to survive in the wild only at the Moroccan sites, although occasional sightings of birds in Yemen, Eritrea, Saudi Arabia, and Israel during the 1980s and 1990s suggested that there was still a colony somewhere in the Middle East. Intensive field surveys in spring 2002, based on the knowledge of Bedouin nomads and local hunters, revealed that the species had never become completely extinct on the Syrian desert steppes. Following systematic searches, 15 old nesting sites were found, one, near Palmyra, was still hosting an active breeding colony of seven individuals. Although the ibis had been declared extinct in Syria more than 70 years earlier, the bird appears to have been relatively common in the desert areas until 20 years ago, when a combination of overexploitation of its range lands and increasing hunting pressures initiated a dramatic decline.The Moroccan breeding birds are resident, dispersing along the coast after the nesting season. It has been suggested that coastal fog provides extra moisture for this population, and enables the ibises to remain year-round. In the rest of its former range, away from the Moroccan coastal locations, the northern bald ibis migrated south for the winter, and formerly occurred as a vagrant to Spain, Iraq, Egypt, the Azores, and Cape Verde.Satellite tagging of 13 Syrian birds in 2006 showed that the three adults in the group, plus a fourth untagged adult, wintered together from February to July in the highlands of Ethiopia, where the species had not been recorded for nearly 30 years. They travelled south on the eastern side of the Red Sea via Saudi Arabia and Yemen, and returned north through Sudan and Eritrea.
Question: What is the full name of the birds that returned through Sudan?
[EX A]:
northern bald ibis.
