The letter was one of the earliest documents on record     6     mentioned tofu in the West.

Alice Thompson is a girl from Sydney, Australia. She had her first long     1     (distant) train ride at the age of 18. Together with a friend, she got     2     the famous Ghan train in Sydney and got off in Alice Springs. During the two days and nights, they ate meals     3     (cook) by experts and saw fields, desert and     4     (abandon) farms. In the daytime, Alice talked to other passengers and read some books.

Buried deep in the ruins of the Shang Dynasty,     1     (specific) in Anyang City of Henan Province, bones of the rhino (犀牛) were found.

A collection of archaeological evidence has confirmed the     2    (exist) of rhinos in ancient China. The animal    3    (distribute) across China’s Central Plains,     4     Chinese civilization originated.

Nevertheless, the rhino was no longer wandering in the region after the Han Dynasty. One explanation is that it was the colder climate of Northeast Asia that saw the creature    5    (appear) from the pages of history. However, Zhou Yu, the writer of History of Chinese Armor (盔甲), offered up    6     explanation: the crafting of armor.

Armor was originally made of bamboo but the material possessed limited    7    (defend) capabilities. Leather armor later became popular during the pre-Qin period. Zhou’s book    8    (read) that the rhino’s thick skin was a primary material for the creation of warriors’ armor. Many ancient accounts recorded the killing of rhinos and     9    (turn) their skin into protective covering. “The huge demand     10     rhino skins might have caused the animal’s disappearance or at least its migration from the Central Plains to the southwestern regions,” Zhou told Beijing Review.

Cholera used to be one of the most feared diseases in the world. In the early 19th century, when cholera     1     (break) out in Europe, John Snow became frustrated because no one knew how to prevent or treat cholera. However, he never lost his desire to destroy cholera once and for all. Snow subscribed     2     the theory that cholera was caused by an infection from germs in food or water. He suspected that the water pump was     3     (blame). Snow began by marking on a map the exact places     4     all those who died had lived. As     5     consequence, John Snow was able to announce that the pump water carried cholera germs.     6     (according), he had the handle of the pump     7     (remove) so that it could not be used. The truth was     8     there was a link between cases of cholera and the different water companies in London. The people who drank this water were much     9     (likely) to get cholera than those who drank pure or boiled water. Fortunately, we now know how to prevent cholera, thanks to the work of John Snow. Moreover, by     10    (use) maps and statistics, Snow transformed the way scientists study diseases. For this reason, Snow is considered the father of modern epidemiology.
