PROBLEM: Although there were a number of department stores in Australia for much of the 20th Century, including chains such as Grace Bros. and Waltons, many disappeared during the 1980s and 1990s. Today Myer and David Jones, located nationally, are practically the national department stores duopoly in Australia. When Russian-born migrant, Sidney Myer, came to Australia in 1899 he formed the Myer retail group with his brother, Elcon Myer. In 1900, they opened the first Myer department store, in Bendigo, Victoria. Since then, the Myer retail group has grown to be Australia's largest retailer. Both, Myer and David Jones, are up-market chains, offering a wide variety of products from mid-range names to luxury brands. Other retail chain stores such as Target (unrelated to the American chain of the same name), Venture (now defunct), Kmart and Big W, also located nationally, are considered to be Australia's discount department stores. Harris Scarfe, though only operating in four states and one territory, is a department store using both the large full-line and small discount department store formats. Most department stores in Australia have their own credit card companies, each having their own benefits while the discount department stores do not have their own credit card rights.

SOLUTION: What were some of the original Australian department stores? 

PROBLEM: Despite being a persistent critic of some of the government's policies, the paper supported Labour in both subsequent elections the party won. For the 2005 general election, The Sun backed Blair and Labour for a third consecutive election win and vowed to give him "one last chance" to fulfil his promises, despite berating him for several weaknesses including a failure to control immigration. However, it did speak of its hope that the Conservatives (led by Michael Howard) would one day be fit for a return to government. This election (Blair had declared it would be his last as prime minister) resulted in Labour's third successive win but with a much reduced majority.

SOLUTION: Who did The Sun endorse in the 2005 general election?

PROBLEM: The migration of birds also aids the movement of other species, including those of ectoparasites such as ticks and lice, which in turn may carry micro-organisms including those of concern to human health. Due to the global spread of avian influenza, bird migration has been studied as a possible mechanism of disease transmission, but it has been found not to present a special risk; import of pet and domestic birds is a greater threat. Some viruses that are maintained in birds without lethal effects, such as the West Nile Virus may however be spread by migrating birds. Birds may also have a role in the dispersal of propagules of plants and plankton.

SOLUTION:
What other species does migration help?
