Input: Consider Input: Question: Were either of the men that Slater accompanied aboard the  HMS Shearwater born in Scotland? Passage:In 1874 he accompanied the botanist Isaac Bayley Balfour and George Gulliver aboard HMS Shearwater on an expedition to observe the transit of Venus on Rodrigues. In addition to studies of the flora and fauna, Slater excavated the subfossil bones of extinct birds, including the Rodrigues solitaire (Pezophaps solitaria) and Rodrigues starling (Necropsar rodericanus). His records were used by the zoologists Albert Günther and Alfred Newton to write the first scientific description of the Rodrigues starling in 1879. During a stay in Mauritius in 1875 he and George Gulliver explored the flora, the herpetofauna, and the aquatic avifauna. In 1885 he traveled with Thomas Carter to Iceland. Based partly on his work there, he wrote the Manual of the Birds of Iceland, published in 1901. In 1897 Slater described the short-tailed parrotbill (Paradoxornis davidianus) and the sulphur-breasted warbler (Phylloscopus ricketti). Together with William Bernhardt Tegetmeier and Frederick William Frohawk, he wrote the fifth volume of British Birds With Their Nests and Eggs (1898). In 1877 Slater was elected a Fellow of the Zoological Society of London (FZS). He was also a member of the British Ornithologists' Union.

Input: Consider Input: Question: Which was created first, Little Quacker (1950) or The Yogi Bear Show? Passage:Another recurring character in the series was Little Quacker the duckling, who was later adapted into the Hanna-Barbera character Yakky Doodle. He appears in Little Quacker (1950), Just Ducky (1953), Downhearted Duckling (1954), Southbound Duckling (1955), That's My Mommy (also 1955), Happy Go Ducky (1958), and The Vanishing Duck (1958). Quacker talks a lot compared to Tom and Jerry. His voice is a 'duck voice' not dissimilar to Disney's Donald Duck. In many shorts, he is the only character who speaks. He is very trusting, even trusting Tom in many situations in which Tom wishes to eat him. He is a friend of Jerry, but unlike Jerry harbors no hard feelings towards Tom. He appeared in The Tom and Jerry Show episode "The Lost Duckling" (1975). He also got his own series of shorts on The Yogi Bear Show (renamed Yakky Doodle) after guesting in several Hanna-Barbera TV shows. Quacker was then used as a template for the 'Hard Luck Duck' character starring in the titular character's short from the What a Cartoon! series. His What a Cartoon! counterpart Hard Luck Duck was voiced by Russi Taylor.

Passage:Matheson was born on April 7, 1949 in Winnipeg, Manitoba to Jack and Peggy Matheson.

He got his first job upon completing school with the Regina Leader-Post, but moved west to Edmonton, Alberta six months later. Upon moving to Edmonton, Matheson got a job with the Edmonton Journal in 1970. He initially covered local curling and university sports, but quickly switched to hockey, when, in 1973, Edmonton was granted a WHA franchise, the Edmonton Oilers. Matheson became the beat writer for the Oilers then, and continued when the Oilers joined the NHL in 1979. He spent countless hours covering the team and its five Stanley Cups, and completed more than 300 stories per winter. In addition to writing, Matheson also was a part of the CFRN radio broadcasting team that covered the Oilers. After 24 years, he completed his tenure as beat writer for the Oilers in 1997. He now continues to write for the Edmonton Journal covering the NHL and the Oilers.
