Here is a question about this article: From its base in India, the Company had also been engaged in an increasingly profitable opium export trade to China since the 1730s. This trade, illegal since it was outlawed by the Qing dynasty in 1729, helped reverse the trade imbalances resulting from the British imports of tea, which saw large outflows of silver from Britain to China. In 1839, the confiscation by the Chinese authorities at Canton of 20,000 chests of opium led Britain to attack China in the First Opium War, and resulted in the seizure by Britain of Hong Kong Island, at that time a minor settlement.
What is the answer to this question: How many chests of opium did China confiscate in 1839?
****
So... 20,000

Here is a question about this article: Street vendors play their trade from stalls in the tianguis as well as at non-officially controlled concentrations around metro stations and hospitals; at plazas comerciales, where vendors of a certain "theme" (e.g. stationery) are housed; originally these were organized to accommodate vendors formerly selling on the street; or simply from improvised stalls on a city sidewalk. In addition, food and goods are sold from people walking with baskets, pushing carts, from bicycles or the backs of trucks, or simply from a tarp or cloth laid on the ground.
What is the answer to this question: Similar tianguis might set up shop where?
****
So... plazas comerciales

Here is a question about this article: After the American Revolutionary War broke out in 1776, the Connecticut colonial government ordered the construction of Black Rock Fort (to be built on top of an older 17th-century fort) to protect the port of New Haven. In 1779, during the Battle of New Haven, British soldiers captured Black Rock Fort and burned the barracks to the ground. The fort was reconstructed in 1807 by the federal government (on orders from the Thomas Jefferson administration), and rechristened Fort Nathan Hale, after the Revolutionary War hero who had lived in New Haven. The cannons of Fort Nathan Hale were successful in defying British war ships during the War of 1812. In 1863, during the Civil War, a second Fort Hale was built next to the original, complete with bomb-resistant bunkers and a moat, to defend the city should a Southern raid against New Haven be launched. The United States Congress deeded the site to the state in 1921, and all three versions of the fort have been restored. The site is now listed on the National Register of Historic Places and receives thousands of visitors each year.
What is the answer to this question: After which revolutionary war hero and New Haven native was Black Rock Fort rechristened upon reconstruction in 1807?
****
So...
Nathan Hale
