Problem: Sichuan:

Sichuan was China's most populous province before Chongqing became a directly-controlled municipality; it is currently the fourth most populous, after Guangdong, Shandong and Henan. As of 1832, Sichuan was the most populous of the 18 provinces in China, with an estimated population at that time of 21 million. It was the third most populous sub-national entity in the world, after Uttar Pradesh, India and the Russian Soviet Federative Socialist Republic until 1991, when the Soviet Union was dissolved. It is also one of the only six to ever reach 100 million people (Uttar Pradesh, Russian RSFSR, Maharashtra, Sichuan, Bihar and Punjab). It is currently 10th.

How many sub-national entities have surpassed 21 million people in total?

A: unanswerable


Problem: Georgian architecture:

After about 1840, Georgian conventions were slowly abandoned as a number of revival styles, including Gothic Revival, that had originated in the Georgian period, developed and contested in Victorian architecture, and in the case of Gothic became better researched, and closer to their originals. Neoclassical architecture remained popular, and was the opponent of Gothic in the Battle of the Styles of the early Victorian period. In the United States the Federalist Style contained many elements of Georgian style, but incorporated revolutionary symbols.

What style from the United States used many elements of Georgian style but with revolutionary symbols?
---
A: Federalist Style


Problem: Letter case:

As regards publication titles it is, however, a common typographic practice among both British and U.S. publishers to capitalise significant words (and in the United States, this is often applied to headings, too). This family of typographic conventions is usually called title case. For example, R. M. Ritter's Oxford Manual of Style (2002) suggests capitalising "the first word and all nouns, pronouns, adjectives, verbs and adverbs, but generally not articles, conjunctions and short prepositions". This is an old form of emphasis, similar to the more modern practice of using a larger or boldface font for titles. The rules for which words to capitalise are not based on any grammatically inherent correct/incorrect distinction and are not universally standardized; they are arbitrary and differ between style guides, although in most styles they tend to follow a few strong conventions, as follows:

Which book of literature standards suggests capitalizing the first word and all nouns, pronouns, adjectives, verbs, and adverbs?

A: R. M. Ritter's Oxford Manual of Style


Problem: Roman Republic:

In process known as the Marian reforms, Roman consul Gaius Marius carried out a programme of reform of the Roman military. In 107 BC, all citizens, regardless of their wealth or social class, were made eligible for entry into the Roman army. This move formalised and concluded a gradual process that had been growing for centuries, of removing property requirements for military service. The distinction between the three heavy infantry classes, which had already become blurred, had collapsed into a single class of heavy legionary infantry. The heavy infantry legionaries were drawn from citizen stock, while non-citizens came to dominate the ranks of the light infantry. The army's higher-level officers and commanders were still drawn exclusively from the Roman aristocracy.

Who would likely make up the majority of the Roman army's light infantry?
---
A:
non-citizens
