Problem: Pacific War:

The largest and bloodiest American battle came at Okinawa, as the U.S. sought airbases for 3,000 B-29 bombers and 240 squadrons of B-17 bombers for the intense bombardment of Japan's home islands in preparation for a full-scale invasion in late 1945. The Japanese, with 115,000 troops augmented by thousands of civilians on the heavily populated island, did not resist on the beaches—their strategy was to maximize the number of soldier and Marine casualties, and naval losses from Kamikaze attacks. After an intense bombardment the Americans landed on 1 April 1945 and declared victory on 21 June. The supporting naval forces were the targets for 4,000 sorties, many by Kamikaze suicide planes. U.S. losses totaled 38 ships of all types sunk and 368 damaged with 4,900 sailors killed. The Americans suffered 75,000 casualties on the ground; 94% of the Japanese soldiers died along with many civilians.

Problem: Hellenistic period:

However, William Woodthorpe Tarn, between World War I and World War II and the heyday of the League of Nations, focused on the issues of racial and cultural confrontation and the nature of colonial rule. Michael Rostovtzeff, who fled the Russian Revolution, concentrated predominantly on the rise of the capitalist bourgeoisie in areas of Greek rule. Arnaldo Momigliano, an Italian Jew who wrote before and after the Second World War, studied the problem of mutual understanding between races in the conquered areas. Moses Hadas portrayed an optimistic picture of synthesis of culture from the perspective of the 1950s, while Frank William Walbank in the 1960s and 1970s had a materialistic approach to the Hellenistic period, focusing mainly on class relations. Recently, however, papyrologist C. Préaux has concentrated predominantly on the economic system, interactions between kings and cities and provides a generally pessimistic view on the period. Peter Green, on the other hand, writes from the point of view of late 20th century liberalism, his focus being on individualism, the breakdown of convention, experiments and a postmodern disillusionment with all institutions and political processes.

Who focused on the issue of racial and cultural confrontation?

A: William Woodthorpe Tarn


Problem: Melbourne:

As the centre of Australia's "rust belt", Melbourne experienced an economic downturn between 1989 to 1992, following the collapse of several local financial institutions. In 1992 the newly elected Kennett government began a campaign to revive the economy with an aggressive development campaign of public works coupled with the promotion of the city as a tourist destination with a focus on major events and sports tourism. During this period the Australian Grand Prix moved to Melbourne from Adelaide. Major projects included the construction of a new facility for the Melbourne Museum, Federation Square, the Melbourne Exhibition and Convention Centre, Crown Casino and the CityLink tollway. Other strategies included the privatisation of some of Melbourne's services, including power and public transport, and a reduction in funding to public services such as health, education and public transport infrastructure.

Which government in 1992 began a campaign to revive the economy?

A: Kennett


Problem: Infection:

In the absence of suitable plate culture techniques, some microbes require culture within live animals. Bacteria such as Mycobacterium leprae and Treponema pallidum can be grown in animals, although serological and microscopic techniques make the use of live animals unnecessary. Viruses are also usually identified using alternatives to growth in culture or animals. Some viruses may be grown in embryonated eggs. Another useful identification method is Xenodiagnosis, or the use of a vector to support the growth of an infectious agent. Chagas disease is the most significant example, because it is difficult to directly demonstrate the presence of the causative agent, Trypanosoma cruzi in a patient, which therefore makes it difficult to definitively make a diagnosis. In this case, xenodiagnosis involves the use of the vector of the Chagas agent T. cruzi, an uninfected triatomine bug, which takes a blood meal from a person suspected of having been infected. The bug is later inspected for growth of T. cruzi within its gut.

What can Mycobacterium leprae and Treponema pallidum be grown in?

A:
animals
