Question: Read the following paragraph and extract the answer for the question: What is the full name of the person who, along with their colleagues, recommended moving the red and pink-headed warblers to the genus Cardellina?  English jeweller and naturalist William Bullock and his son travelled to Mexico soon after its independence, spending six months in 1823 collecting archeological artifacts and many bird and fish species new to science. The bird specimens were given to naturalist William John Swainson, their countryman, to formally describe, which he did in 1827. Among these was the red warbler, which was assigned to the genus Setophaga, as Setophaga rubra. Over the next half century, other authorities moved it to Cardellina, with the red-faced warbler, and to the widespread tropical warbler genus Basileuterus, as well as to the Old World warbler genus Sylvia and the Old World tit genus Parus. In 1873, English naturalists Philip Lutley Sclater and Osbert Salvin moved the species to the genus Ergaticus, where it remained for more than a century.The red warbler forms a superspecies with the pink-headed warbler of Chiapas and Guatemala. Despite their disjunct ranges and considerably different plumages, the two have sometimes been considered conspecific. Conversely, it has also been suggested that the red warbler should be split into a northern gray-eared species (C. melanauris) and a southern white-eared species (C. rubra). A comprehensive 2010 paper by Irby Lovette and colleagues analysing mitochondrial and nuclear DNA of the New World warblers found that the red and pink-headed warblers are each others' closest relative and that their common ancestor diverged from a lineage that gave rise to the red-faced warbler. The authors recommended moving the red and pink-headed warblers to the genus Cardellina, a suggestion which has been adopted by the International Ornithologists' Union (IOC).There are three subspecies, which differ slightly in appearance: C. r. rubra, described by Swainson in 1827, has white ear patches and is found from southern Jalisco and southern Hidalgo to Oaxaca.
Answer: Irby Lovette

[Q]: Read the following paragraph and extract the answer for the question: Who owns the car the Bulter's crashed?  Sam Clayton is too good for his own good. A sermon by Rev. Daniels persuades him to help others in every way he can, including his wife Lu's good-for-nothing brother, Claude, who's been living with them rent-free for six months, and their neighbors the Butlers, who need a car for a vacation when theirs breaks down. Sam is a department store manager whose boss, H.C. Borden, wants him to sell more and socialize less. Sam's a shoulder for clerk Shirley Mae to cry on when her romance breaks up. He also gives a $5,000 loan, without his wife's knowledge, to Mr. and Mrs. Adams, who need it to save a gas station they bought. Lu is fed up with Sam's generosity, particularly when he ends up paying for the Butlers' car repairs, then letting the mechanic come over for home-cooked meals. The last straw for Lu comes when she learns they have a chance to put a down payment on a new house, except Sam has lent their nest egg to the Adamses. Sam is unhappy, too. He's annoyed with the Butlers, who have crashed his car and can't pay to fix it. He also wants Claude to move out. Shirley Mae's troubles come to his door after she takes too many pills. Sam even gets robbed, and the bank refuses to make him a loan. He is at his wit's end when the Adamses surprise him with a check for $6,000. They also give Claude a job, and Shirley Mae suddenly thinks she and Claude could have a future together. Sam and Lu feel better about life, particularly when Borden surprises him with a promotion at work.

[A]: Sam Clayton

input: Please answer the following: Read the following paragraph and extract the answer for the question: What genres are defined chiefly by lyrical focus?  The term "Viking metal" has sometimes been used as a nickname for the 1990s Norwegian black metal scene, which was "noisy, chaotic, and often augmented by sorrowful keyboard melodies". It has also been variously described as a subgenre of black metal, albeit one that abandoned black metal's Satanic imagery, "slow black metal" with influences from Nordic folk music, straddling black metal and folk metal almost equally, or running the gamut from "folk to black to death metal". Typically, Viking metal artists rely extensively on keyboards, which are often played at a "swift, galloping pace". These artists often add "local cultural flourishes" such as traditional instruments and ethnic melodies. It is similar to folk metal, and is sometimes categorized as such, but it uses folk instruments less extensively. For vocals, Viking metal incorporates both singing and the typical black metal screams and growls. Overall, Viking metal is hard to define since, apart from certain elements like anthem-like choruses, it is not based entirely on musical features and overlaps with other metal genres, with origins in black and death metal Some bands, such as Unleashed and Amon Amarth, play death metal, but incorporate Viking themes and thus are labeled as part of the genre. Generally, Viking metal is defined more by its thematic material and imagery than musical qualities. Rather than being a mock-up of medieval music, "it is in the band names, album titles, artwork of album covers and, especially, in the song lyrics that Viking themes are so evident." Viking metal, and the closely related style pagan metal, is more of a term or "etiquette" than a musical style. Since they are defined chiefly by lyrical focus, any musical categorizations of these two styles is controversial. Thus, Viking metal is more of a cross-genre term than a descriptor of a certain sound. Ashby and Schofield write that "The term 'Viking metal' is one of many that falls within a complex web of genres and subgenres, the precise form of which is constantly...
