Problem: 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.
How many chests of opium did China confiscate in 1839?
The answer is the following: 20,000

Problem: Mexico City is one of the most important economic hubs in Latin America. The city proper (Federal District) produces 15.8% of the country's gross domestic product. According to a study conducted by PwC, Mexico City had a GDP of $390 billion, ranking it as the eighth richest city in the world after the greater metropolitan areas of Tokyo, New York City, Los Angeles, Chicago, Paris, London and Osaka/Kobe (and the richest in the whole of Latin America). Excluding the rest of the Mexican economy, Mexico City alone would rank as the 30th largest economy in the world. Mexico City is the greatest contributor to the country's industrial GDP (15.8%) and also the greatest contributor to the country's GDP in the service sector (25.3%). Due to the limited non-urbanized space at the southmost of which is protected through environmental lawsthe contribution of the Federal District in agriculture is the smallest of all federal entities in the country. Mexico City has one of the world's fastest-growing economies and its GDP is set to double by 2020.
What is the GDP of Mexico City?
The answer is the following: $390 billion

Problem: The New York Times reported that "government officials in Beijing and Sichuan have said they are investigating the collapses. In an acknowledgment of the weakness of building codes in the countryside, the National Development and Reform Commission said on May 27 that it had drafted an amendment to improve construction standards for primary and middle schools in rural areas. Experts are reviewing the draft, the commission said." To limit protests, officials pushed parents to sign a document, which forbade them from holding protests, in exchange of money, but some who refused to sign were threatened. The payment amounts varied from school to school but were approximately the same. In Hanwang, parents were offered a package valued at 8,800 USD in cash and a per-parent pension of nearly 5,600 USD. Furthermore, officials used other methods of silencing: riot police officers broke up protests by parents; the authorities set up cordons around the schools; and officials ordered the Chinese news media to stop reporting on school collapses.
What are officials offering parents in exchange of protests?
The answer is the following: money

Problem: This growing coalition expanded the potential enemies that Rome might face, and moved Rome closer to confrontation with major powers. The result was more alliance-seeking, on the part of both the Roman confederacy and city-states seeking membership (and protection) within that confederacy. While there were exceptions to this (such as military rule of Sicily after the First Punic War), it was not until after the Second Punic War that these alliances started to harden into something more like an empire, at least in certain locations. This shift mainly took place in parts of the west, such as the southern Italian towns that sided with Hannibal.
What towns had chosen Hannibal's side?
The answer is the following:
southern Italian
