Problem: Nutrition:

A dramatic example of the effect of food processing on a population's health is the history of epidemics of beri-beri in people subsisting on polished rice. Removing the outer layer of rice by polishing it removes with it the essential vitamin thiamine, causing beri-beri. Another example is the development of scurvy among infants in the late 19th century in the United States. It turned out that the vast majority of sufferers were being fed milk that had been heat-treated (as suggested by Pasteur) to control bacterial disease. Pasteurisation was effective against bacteria, but it destroyed the vitamin C.

What did people who became ill with beri-beri have as their main food source?
---
A: polished rice

Problem: Antibiotics:

In 1939, coinciding with the start of World War II, Rene Dubos reported the discovery of the first naturally derived antibiotic, tyrothricin, a compound of 20% gramicidin and 80% tyrocidine, from B. brevis. It was one of the first commercially manufactured antibiotics universally and was very effective in treating wounds and ulcers during World War II. Gramicidin, however, could not be used systemically because of toxicity. Tyrocidine also proved too toxic for systemic usage. Research results obtained during that period were not shared between the Axis and the Allied powers during the war.

What was tyrothricin used for during toxicity?
---
A: unanswerable

Problem: Hokkien:

There are many Hokkien speakers among overseas Chinese in Southeast Asia as well as in the United States. Many ethnic Han Chinese emigrants to the region were Hoklo from southern Fujian, and brought the language to what is now Burma (Myanmar), Indonesia (the former Dutch East Indies) and present day Malaysia and Singapore (formerly Malaya and the British Straits Settlements). Many of the Hokkien dialects of this region are highly similar to Taiwanese and Amoy. Hokkien is reportedly the native language of up to 98.5% of the Chinese Filipino in the Philippines, among which is known locally as Lan-nang or Lan-lang-oe ("Our people's language"). Hokkien speakers form the largest group of Chinese in Singapore, Malaysia and Indonesia.[citation needed]

What group brought the Amoy language to Burma, Malaysia and Singapore?
