Here is a question about this article: By the end of the 18th century the population had risen to 300 million from approximately 150 million during the late Ming dynasty. The dramatic rise in population was due to several reasons, including the long period of peace and stability in the 18th century and the import of new crops China received from the Americas, including peanuts, sweet potatoes and maize. New species of rice from Southeast Asia led to a huge increase in production. Merchant guilds proliferated in all of the growing Chinese cities and often acquired great social and even political influence. Rich merchants with official connections built up huge fortunes and patronized literature, theater and the arts. Textile and handicraft production boomed.
What is the answer to this question: What crops were imported?
****
So... peanuts, sweet potatoes and maize. New species of rice


Here is a question about this article: Some organizations have begun working with teachers, policymakers, and managed foodservice contractors to mandate improved nutritional content and increased nutritional resources in school cafeterias from primary to university level institutions. Health and nutrition have been proven to have close links with overall educational success. Currently, less than 10% of American college students report that they eat the recommended five servings of fruit and vegetables daily. Better nutrition has been shown to have an impact on both cognitive and spatial memory performance; a study showed those with higher blood sugar levels performed better on certain memory tests. In another study, those who consumed yogurt performed better on thinking tasks when compared to those that consumed caffeine-free diet soda or confections. Nutritional deficiencies have been shown to have a negative effect on learning behavior in mice as far back as 1951.
What is the answer to this question: Which animal was shown to have a negative effect on learning behavior due to nutritional deficiencies back in 1951?
****
So... mice


Here is a question about this article: The Western powers, largely unsatisfied with the Treaty of Nanjing, gave grudging support to the Qing government during the Taiping and Nian Rebellions. China's income fell sharply during the wars as vast areas of farmland were destroyed, millions of lives were lost, and countless armies were raised and equipped to fight the rebels. In 1854, Britain tried to re-negotiate the Treaty of Nanjing, inserting clauses allowing British commercial access to Chinese rivers and the creation of a permanent British embassy at Beijing.
What is the answer to this question: When did the British try to redo the Treaty of Nanjing?
****
So...
1854
