Problem: Read the following paragraph and extract the answer for the question: What animal's species is easiest to tell apart by their call?  The territorial call of the Australian raven is a slow, high ah-ah-aaaah with the last note drawn out. It uses this call to communicate with other Australian ravens in the area. When giving this call, the species has a horizontal posture, holding its head forward and body parallel to the ground, while perched on a prominent position. It ruffles its hackles and lowers its tail, and sometimes holds its beak open between calls. In contrast, the little raven and forest raven hold their bodies in an upright posture. This call becomes louder if trespassers encroach upon the Australian raven's territory. The five Australian species are very difficult to tell apart, with the call being the easiest way to do so, although the drawing-out of the final note—long held to be solely recorded for the Australian raven—has been recorded for the other species and is hence not diagnostic.The volume, pitch, tempo and order of notes can be changed depending on the message the Australian raven intends to convey. There is a variety of contact calls: a pair often makes a low murmuring sound when preening each other while roosting, and members of a flock carry on with a quiet chattering while at rest. Birds make a call and answer sequence if temporarily out of sight of one another while foraging. Birds in flocks make a single high-pitched caa while flying over another territory as a transit call to signify they are just passing through. An Australian raven will give a longer caa with a downward inflection to signify its return to the nest to its mate.

A: Australian raven


Problem: Read the following paragraph and extract the answer for the question: What is the full name of the person who knew that John had died?  For 27 years, invalid Katherine Chandler has been waiting for her missing son John to return to her. A nearby college buys her apartment building and intends to evict her and construct a men's dormitory, but Katherine has a lease that stipulates she cannot be moved without her consent. Workmen begin the construction all around her unit, but rather than drive her away, Katherine charms the young men and invites them for tea. Assisted by her longtime chauffeur Tom McKay, she is carried up and down the stairs in her chair by the workers and students. One night, Julie Horton breaks in through the fire escape. Julie is having trouble with her boyfriend Johnny, a former Marine who is now in school.  Katherine wants to meet him. She begins to wonder if this could be the son of her long-lost Johnny and quickly begins to enjoy his company and trust him. Johnny's grades and behavior are poor, resulting in him being expelled.

A: Tom McKay


Problem: Read the following paragraph and extract the answer for the question: What is the first name of the person who employed a wide variety of musical styles from the time of his earliest recordings?  From the time of his earliest recordings in the 1960s, Bowie employed a wide variety of musical styles. His early compositions and performances were strongly influenced by rock and rollers like Little Richard and Elvis Presley, and also the wider world of show business. He particularly strove to emulate the British musical theatre singer-songwriter and actor Anthony Newley, whose vocal style he frequently adopted, and made prominent use of for his 1967 debut release, David Bowie (to the disgust of Newley himself, who destroyed the copy he received from Bowie's publisher). Bowie's music hall fascination continued to surface sporadically alongside such diverse styles as hard rock and heavy metal, soul, psychedelic folk, and pop.Musicologist James Perone observes Bowie's use of octave switches for different repetitions of the same melody, exemplified in his commercial breakthrough single, "Space Oddity", and later in the song "Heroes", to dramatic effect; Perone notes that "in the lowest part of his vocal register ... his voice has an almost crooner-like richness."Voice instructor Jo Thompson describes Bowie's vocal vibrato technique as "particularly deliberate and distinctive". Schinder and Schwartz call him "a vocalist of extraordinary technical ability, able to pitch his singing to particular effect." Here, too, as in his stagecraft and songwriting, the singer's role playing is evident: historiographer Michael Campbell says that Bowie's lyrics "arrest our ear, without question. But Bowie continually shifts from person to person as he delivers them ... His voice changes dramatically from section to section." In a 2014 analysis of 77 "top" artists' vocal ranges, Bowie was 8th, just behind Christina Aguilera and just ahead of Paul McCartney. In addition to the guitar, Bowie also played a variety of keyboards, including piano, Mellotron, Chamberlin, and synthesizers; harmonica; alto and baritone saxophones; stylophone; viola; cello; koto (in the Heroes track "Moss Garden"); thumb piano; drums (on the Heathen...

Problem: Read the following paragraph and extract the answer for the question: What is the first name of the person that tries out his father's fishing rod?  It's Christmas Eve and Richie Rich, the world's richest kid, is all excited to spend the day with his friends. While racing wildly with his friends in the snow, Richie's butler, Herbert Cadbury, controls the cars using a remote and guides the children back to Richie's house. He then reminds him about his responsibilities that are due to be executed on Christmas Eve, and instructs him to change his clothes and get ready for tea. Before going to do so, he visits his home scientist, Professor Keanbean, who shows him his recent invention, a wishing machine which works only on Christmas Eve. The day being that, Richie wishes for a "big pie" from it, and is given a "pig sty" instead. Cadbury is disgusted seeing this, and sends him off to change his clothes. He meets his parents, Richard and Regina Rich, to ask what they would like to have for Christmas. While with them, he also tries out his father's new fishing rod invented by Keanbean, which hooks on to a tuna sandwich in the vicinity. He then goes on to change his clothes. During tea, Richie meets his spoiled cousin, Reggie Van Dough, who wishes that he was as rich as Richie. Later, he dresses up like an elf with Cadbury as Santa Claus to distribute Christmas presents to the orphanage. While getting ready, Cadbury tells Richie about how he was a rock star in his youth days, in a band called Root Canal. When they take off in the sleigh with Richie driving it, Reggie takes control of it using the remote invented by Keanbean that Cadbury used earlier. He guides it through streets by shops, houses, and people, thus nearly destroying everything in the whole process. Richie and Cadbury end up in an accident in which the sleigh falls and literally explodes along with the presents, while Cadbury hurts his ankle badly. Richie runs off to fetch help, but once he enters the city, he sees that the situation has changed dramatically. Reggie is cooking up rumors about him, and all the people have turned against him.

A:
Richie
