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: As far as we know, the earliest cantatas of Johann Sebastian Bach were performed in Mühlhausen from 1706 to 1708. He was employed as an organist there, but he occasionally composed cantatas, mostly for special occasions. The cantatas were based mainly on biblical texts and hymns, such as Aus der Tiefen rufe ich, Herr, zu dir, BWV 131 (a psalm setting), and the Easter chorale cantata Christ lag in Todes Banden, BWV 4.
Bach was next appointed organist and chamber musician in Weimar on 25 June 1708 at the court of the co-reigning dukes in Saxe-Weimar, Wilhelm Ernst and his nephew Ernst August. He initially concentrated on the organ, composing major works for the instrument, including the Orgelbüchlein, the Toccata and Fugue in D minor, BWV 565, and the Prelude and Fugue in E major, BWV 566. He was promoted to Konzertmeister on 2 March 1714, an honour that entailed performing a church cantata monthly in the Schlosskirche. The first cantatas he composed in the new position were Himmelskönig, sei willkommen, BWV 182, for Palm Sunday, Weinen, Klagen, Sorgen, Zagen, BWV 12 for Jubilate Sunday, and Erschallet, ihr Lieder, BWV 172, for Pentecost. Mostly inspired by texts by the court poet, Salomo Franck, they contain recitatives and arias. When Johann Samuel Drese, the Kapellmeister (director of music), died in 1716, Bach hoped in vain to become his successor. Bach looked for a better position and found it as Kapellmeister at the court of Leopold, Prince of Anhalt-Köthen. However, the duke in Weimar did not dismiss him and arrested him for disobedience. He was released on 2 December 1717.In Köthen, Bach found an employer who was an enthusiastic musician himself. The court was Calvinist, therefore Bach's work from this period was mostly secular, including the orchestral suites, the cello suites, the sonatas and partitas for solo violin, and the Brandenburg Concertos. He composed secular cantatas for the court for occasions such as New Year's Day and the prince's birthday, including Die Zeit, die Tag und Jahre macht, BWV 134a. He later parodied some of them as church cantatas without major changes, for example Ein Herz, das seinen Jesum lebend weiß, BWV 134. 
Question: What is full the name of the person whose successor Bach hoped in vain to become?
[EX A]: Johann Samuel Drese.

[EX Q]: 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 road did Interstate 40 replace?
[EX A]: U.S. Route 66.

[EX Q]: Passage: Mother rodents provide both direct parental care, such as nursing, grooming, retrieving and huddling, and indirect parenting, such as food caching, nest building and protection to their offspring. In many social species, young may be cared for by individuals other than their parents, a practice known as alloparenting or cooperative breeding. This is known to occur in black-tailed prairie dogs and Belding's ground squirrels, where mothers have communal nests and nurse unrelated young along with their own. There is some question as to whether these mothers can distinguish which young are theirs. In the Patagonian mara, young are also placed in communal warrens, but mothers do not permit youngsters other than their own to nurse.Infanticide exists in numerous rodent species and may be practiced by adult conspecifics of either sex. Several reasons have been proposed for this behavior, including nutritional stress, resource competition, avoiding misdirecting parental care and, in the case of males, attempting to make the mother sexually receptive. The latter reason is well supported in primates and lions but less so in rodents. Infanticide appears to be widespread in black-tailed prairie dogs, including infanticide from invading males and immigrant females, as well as occasional cannibalism of an individual's own offspring. To protect against infanticide from other adults, female rodents may employ avoidance or direct aggression against potential perpetrators, multiple mating, territoriality or early termination of pregnancy. Feticide can also occur among rodents; in Alpine marmots, dominant females tend to suppress the reproduction of subordinates by being antagonistic towards them while they are pregnant. The resulting stress causes the fetuses to abort. 
Question: What rodents are raised communally but kept from nursing from anyone other than their own moms?
[EX A]:
Patagonian mara.
