Problem: Ship transport is an important component of Melbourne's transport system. The Port of Melbourne is Australia's largest container and general cargo port and also its busiest. The port handled two million shipping containers in a 12-month period during 2007, making it one of the top five ports in the Southern Hemisphere. Station Pier on Port Phillip Bay is the main passenger ship terminal with cruise ships and the Spirit of Tasmania ferries which cross Bass Strait to Tasmania docking there. Ferries and water taxis run from berths along the Yarra River as far upstream as South Yarra and across Port Phillip Bay.
Which is Australia's busiest port?

Answer: The Port of Melbourne

The mid-1970s saw the introduction of dbx-encoded records, again for the audiophile niche market. These were completely incompatible with standard record playback preamplifiers, relying on the dbx compandor encoding/decoding scheme to greatly increase dynamic range (dbx encoded disks were recorded with the dynamic range compressed by a factor of two in dB: quiet sounds were meant to be played back at low gain and loud sounds were meant to be played back at high gain, via automatic gain control in the playback equipment; this reduced the effect of surface noise on quiet passages). A similar and very short-lived scheme involved using the CBS-developed "CX" noise reduction encoding/decoding scheme.
When were DBX recordings released?
A: mid-1970s

Context and question: There is no green pigment in green eyes; like the color of blue eyes, it is an optical illusion; its appearance is caused by the combination of an amber or light brown pigmentation of the stroma, given by a low or moderate concentration of melanin, with the blue tone imparted by the Rayleigh scattering of the reflected light. Green eyes are most common in Northern and Central Europe. They can also be found in Southern Europe, West Asia, Central Asia, and South Asia. In Iceland, 89% of women and 87% of men have either blue or green eye color. A study of Icelandic and Dutch adults found green eyes to be much more prevalent in women than in men. Among European Americans, green eyes are most common among those of recent Celtic and Germanic ancestry, about 16%.
What is the appearance of green in th eyes attributed to?
Answer: an optical illusion

Question: Think-tanks such as the World Pensions Council have also argued that European legislators have pushed somewhat dogmatically for the adoption of the Basel II recommendations, adopted in 2005, transposed in European Union law through the Capital Requirements Directive (CRD), effective since 2008. In essence, they forced European banks, and, more importantly, the European Central Bank itself e.g. when gauging the solvency of financial institutions, to rely more than ever on standardised assessments of credit risk marketed by two non-European private agencies: Moody's and S&P.
Is there an answer to this question: What said that agencies had to start using Moody's and S&P to assess financial institutions?

Answer: the Basel II recommendations

Immunization against the pathogens that cause diarrheal disease is a viable prevention strategy, however it does require targeting certain pathogens for vaccination. In the case of Rotavirus, which was responsible for around 6% of diarrheal episodes and 20% of diarrheal disease deaths in the children of developing countries, use of a Rotavirus vaccine in trials in 1985 yielded a slight (2-3%) decrease in total diarrheal disease incidence, while reducing overall mortality by 6-10%. Similarly, a Cholera vaccine showed a strong reduction in morbidity and mortality, though the overall impact of vaccination was minimal as Cholera is not one of the major causative pathogens of diarrheal disease. Since this time, more effective vaccines have been developed that have the potential to save many thousands of lives in developing nations, while reducing the overall cost of treatment, and the costs to society.
What requires targeting disease for vaccination?
A:
unanswerable
