a. homemade soymilk
b. tofu made using gypsum as the coagulant

Answer: homemade soymilk (a).
Most of the calcium naturally present in whole soybeans is lost when preparing soymilk.

Tofu, made from soymilk, is an excellent source of calcium when made using a calcium-rich coagulant such as gypsum.

Question: When were soybeans first planted in North America?

a. 1765
b. 1801
c. 1844

Answer: 1765 (a).
Introduction of the Soybean to North America by Samuel Bowen in 1765 (1)
Theodore Hymowitz and J.R. Harlan (2)

This paper documents the history of the introduction of the soybean (Glycine max), a domesticate of China, to North America. Henry Yonge, the Surveyor-General of Georgia, planted soybeans on his farm at the request of Samuel Bowen in 1765. Mr. Bowen, a former seaman employed by the East India Company, brought soybeans to Savannah, Georgia, from China via London. From 1766, Mr. Bowen planted soybeans on his plantation "Greenwich" located at Thunderbolt, Georgia. The soybeans were used to manufacture soy sauce and vermicelli (soybean noodles). In addition, he manufactured a sago powder substitute made from sweet potatoes. The 3 products were then exported to England. Samuel Bowen received a patent for his manufacturing inventions for producing these products. Another early introduction of soybeans to North America was by Benjamin Franklin. In 1770 he sent seeds from London to John Bartram in Philadelphia.

Question: Which country was the second largest leading soybean producer and exporter in 2000/2001?

a. US
b. Brazil
c. China

Answer: Brazil (b).
Generous rainfall was very favorable for soybeans in the major producing areas of the south and center-west, although drought cut yields in the northern states. Based on slight increases in area and yield, Brazilís 2001 soybean harvest grew to a record 38.4 million metric tons. With a soybean carryover slightly larger than the previous season, greater supply availability helped boost Brazilian exports to a record 15.0 million tons in 2000/01.
