Problem: Glacier:

A glacier (US /ˈɡleɪʃər/ or UK /ˈɡlæsiə/) is a persistent body of dense ice that is constantly moving under its own weight; it forms where the accumulation of snow exceeds its ablation (melting and sublimation) over many years, often centuries. Glaciers slowly deform and flow due to stresses induced by their weight, creating crevasses, seracs, and other distinguishing features. They also abrade rock and debris from their substrate to create landforms such as cirques and moraines. Glaciers form only on land and are distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water.

What other kinds of ice are thicker than glaciers?

Problem: Swaziland's most well-known cultural event is the annual Umhlanga Reed Dance. In the eight-day ceremony, girls cut reeds and present them to the queen mother and then dance. (There is no formal competition.) It is done in late August or early September. Only childless, unmarried girls can take part. The aims of the ceremony are to preserve girls' chastity, provide tribute labour for the Queen mother, and to encourage solidarity by working together. The royal family appoints a commoner maiden to be "induna" (captain) of the girls and she announces over the radio the dates of the ceremony. She will be an expert dancer and knowledgeable on royal protocol. One of the King's daughters will be her counterpart.
What fosters loyalty to the Queen Mother?

The city's University publishes the UCC Express and Motley magazine.

Context and question: The city's municipal government was dominated by about 12–15 merchant families, whose wealth came from overseas trade with continental Europe — in particular the export of wool and hides and the import of salt, iron and wine. The medieval population of Cork was about 2,100 people. It suffered a severe blow in 1349 when almost half the townspeople died of plague when the Black Death arrived in the town. In 1491, Cork played a part in the English Wars of the Roses when Perkin Warbeck a pretender to the English throne, landed in the city and tried to recruit support for a plot to overthrow Henry VII of England. The then mayor of Cork and several important citizens went with Warbeck to England but when the rebellion collapsed they were all captured and executed. The title of Mayor of Cork was established by royal charter in 1318, and the title was changed to Lord Mayor in 1900 following the knighthood of the incumbent Mayor by Queen Victoria on her Royal visit to the city.
Who did Henry VII want to overthrow in 1491?
Answer: unanswerable


Question: There are several theories to the Islamisation process in Southeast Asia. Another theory is trade. The expansion of trade among West Asia, India and Southeast Asia helped the spread of the religion as Muslim traders from Southern Yemen (Hadramout) brought Islam to the region with their large volume of trade. Many settled in Indonesia, Singapore, and Malaysia. This is evident in the Arab-Indonesian, Arab-Singaporean, and Arab-Malay populations who were at one time very prominent in each of their countries. The second theory is the role of missionaries or Sufis.[citation needed] The Sufi missionaries played a significant role in spreading the faith by introducing Islamic ideas to the region. Finally, the ruling classes embraced Islam and that further aided the permeation of the religion throughout the region. The ruler of the region's most important port, Malacca Sultanate, embraced Islam in the 15th century, heralding a period of accelerated conversion of Islam throughout the region as Islam provided a positive force among the ruling and trading classes.
Is there an answer to this question: Where did the traders from Yemen settle?

Answer: Indonesia, Singapore, and Malaysia


QUES: 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?
What is the answer?
ANS:
polished rice
