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.

Q: Passage: The white-naped xenopsaris (Xenopsaris albinucha), also known as the reed becard and white-naped becard, is a species of suboscine bird in the family Tityridae, the only member of the genus Xenopsaris. It is found in South America, in humid subtropical and tropical savanna climates in most of the countries east of the Andes: Venezuela, Brazil, Bolivia, Paraguay, Uruguay, and Argentina. Living in open woodland and other open forest habitats, it is mostly sedentary, though some populations may be migratory. The species, which is closely related to becards and tityras, was thought to be either a tyrant-flycatcher or cotinga, before it was placed in Tityridae.
The bird is 12.5 to 13 cm (4.9–5.1 in) in length, with whitish undersides, a black crown, and grey-brown upperparts. The sexes are similar in appearance, though the females have duller upperparts. It feeds on insects in the foliage of trees and bushes, and sometimes on the ground. Nesting occurs in a simple cup nest placed in the fork of a tree. Both parents incubate the eggs and help feed the chicks. When the chicks fledge, the parents may divide up the brood to continue helping. The species is not common and little is known about it, but it is not considered in danger of extinction, and has been classified as of least concern by the International Union for Conservation of Nature. 
Question: What is the scientific name of the animal that is 12.5 to 13 cm?

A: Xenopsaris albinucha.

Q: Passage: Carmen (French pronunciation: ​[kaʁmɛn]; Spanish: [ˈkaɾmen]) is an opera in four acts by French composer Georges Bizet. The libretto was written by Henri Meilhac and Ludovic Halévy, based on a novella of the same title by Prosper Mérimée. The opera was first performed by the Opéra-Comique in Paris on 3 March 1875, where its breaking of conventions shocked and scandalized its first audiences.
Bizet died suddenly after the 33rd performance, unaware that the work would achieve international acclaim within the following ten years.  Carmen has since become one of the most popular and frequently performed operas in the classical canon;  the "Habanera" from act 1 and the "Toreador Song" from act 2 are among the best known of all operatic arias.
The opera is written in the genre of opéra comique with musical numbers separated by dialogue. It is set in southern Spain and tells the story of the downfall of Don José, a naïve soldier who is seduced by the wiles of the fiery gypsy Carmen. José abandons his childhood sweetheart and deserts from his military duties, yet loses Carmen's love to the glamorous torero Escamillo, after which José kills her in a jealous rage. The depictions of proletarian life, immorality, and lawlessness, and the tragic death of the main character on stage, broke new ground in French opera and were highly controversial.
After the premiere, most reviews were critical, and the French public was generally indifferent. Carmen initially gained its reputation through a series of productions outside France, and was not revived in Paris until 1883. Thereafter, it rapidly acquired popularity at home and abroad. Later commentators have asserted that Carmen forms the bridge between the tradition of opéra comique and the realism or verismo that characterised late 19th-century Italian opera.
The music of Carmen has since been widely acclaimed for brilliance of melody, harmony, atmosphere, and orchestration, and for the skill with which Bizet musically represented the emotions and suffering of his characters. After the composer's death, the score was subject to significant amendment, including the introduction of recitative in place of the original dialogue; there is no standard edition of the opera, and different views exist as to what versions best express Bizet's intentions. The opera has been recorded many times since the first acoustical recording in 1908, and the story has been the subject of many screen and stage adaptations. 
Question: What is the name of the man in the play that naïve soldier loses the love of the gypsy woman to?

A: Escamillo.

Q: Passage: The hartebeest (; Alcelaphus buselaphus), also known as kongoni, is an African antelope. Eight subspecies have been described, including two sometimes considered to be independent species. A large antelope, the hartebeest stands just over 1 m (3.3 ft) at the shoulder, and has a typical head-and-body length of 200 to 250 cm (79 to 98 in). The weight ranges from 100 to 200 kg (220 to 440 lb). It has a particularly elongated forehead and oddly shaped horns, short neck, and pointed ears. Its legs, which often have black markings, are unusually long. The coat is generally short and shiny. Coat colour varies by the subspecies, from the sandy brown of the western hartebeest to the chocolate brown of the Swayne's hartebeest. Both sexes of all subspecies have horns, with those of females being more slender. Horns can reach lengths of 45–70 cm (18–28 in). Apart from its long face, the large chest and the sharply sloping back differentiate the hartebeest from other antelopes.
Gregarious animals, hartebeest form herds of 20 to 300 individuals. They are very alert and non-aggressive. They are primarily grazers, with their diets consisting mainly of grasses. Mating in hartebeest takes place throughout the year with one or two peaks, and depends upon the subspecies and local factors. Both males and females reach sexual maturity at one to two years of age. Gestation is eight to nine months long, after which a single calf is born. Births usually peak in the dry season. The lifespan is 12 to 15 years. 
Question: What is the common English name of the animal that has eight subspecies?

A:
African antelope.
