Answer:
The responses of the Public Health Departments in Europe and in the United States represented the ideas prevalent in society and in the scientific community. While most of the measures were solidly grounded in the current scientific concepts, they could also be traced back to Medieval and even Classical times of plague and pestilence. The idea of contagion prompting quarantines and isolation dates back to the Justinian Plague. However, epidemiological work by Snow and others in the 19th century did further these notions of contagion and understanding of transmission. Public Health Departments grew out of these advances and the belief in the ability of man to control nature. Sanitation, vaccination programs and other public hygiene efforts in the late 19th century enabled public health officials to gain power and authority. However, the Influenza Pandemic of 1918-19 challenged the public health agencies.

Rice fell by ⅔<span>
between 1929 and 1932. The price of persisted high all over in Asia in the
summer of 1930. In 1930, Japan had a
very abundant rice harvest. Before, the Japanese government was trailing a
deflationary policy in order to sustain the yen, which had just been pegged to
the gold standard. The twice impact of deflation and the rich harvest
caused the rice price to decrease by about one-third in October 1930. This
should have been an only local concern since Japan did not export or import
rice, but grain traders all over the world understood this as an indication
that the rice price would now be part the fate of the wheat price. In November
1930, the rice price in Liverpool was bargained by half, and Calcutta followed
the Liverpool precedent in January 1931. At that point, the rice price
experienced a free fall, and by 1933 rice was low-priced than wheat in India.
Actually, the making, consumption, and export volume of rice did not drop very
much in this period—only the price continued to be low, and so did the income
of the producers.</span>
