Article: Nanjing, one of the nation's most important cities for over a thousand years, is recognized as one of the Four Great Ancient Capitals of China, and had been the world's largest city aggregately for hundreds of years, enjoyed peace and prosperity and beared wars and disasters. Nanjing served as the capital of Eastern Wu, one of the three major states in the Three Kingdoms period (211-280); the Eastern Jin and each of the Southern Dynasties (Liu Song, Southern Qi, Liang and Chen), which successively ruled southern China from 317-589; the Southern Tang, one of the Ten Kingdoms (937-76); the Ming dynasty when, for the first time, all of China was ruled from the city (1368-1421); and the Republic of China (192737, 194549) prior to its flight to Taiwan during the Chinese Civil War. The city also served as the seat of the rebel Taiping Heavenly Kingdom (185164) and the Japanese puppet regime of Wang Jingwei (194045) during the Second Sino-Japanese War, and suffered appalling atrocities in both conflicts, including the Nanjing Massacre. It has been serving as the capital city of Jiangsu province after the China was established, and is still the nominal capital of Republic of China that accommodates many of its important heritage sites, including the Presidential Palace and Sun Yat-sen Mausoleum. Nanjing is famous for human historical landscapes, mountains and waters such as Fuzimiao, Ming Palace, Chaotian Palace, Porcelain Tower, Drum Tower, Stone City, City Wall, Qinhuai River, Xuanwu Lake and Purple Mountain. Key cultural facilities include Nanjing Library, Nanjing Museum and Art Museum.

Here is a question about this article: In 1938 Otto Hahn and Fritz Strassmann discovered nuclear fission with radiochemical methods, and in 1939 Lise Meitner and Otto Robert Frisch wrote the first theoretical interpretation of the fission process, which was later improved by Niels Bohr and John A. Wheeler. Further developments took place during World War II, which led to the practical application of radar and the development and use of the atomic bomb. Though the process had begun with the invention of the cyclotron by Ernest O. Lawrence in the 1930s, physics in the postwar period entered into a phase of what historians have called "Big Science", requiring massive machines, budgets, and laboratories in order to test their theories and move into new frontiers. The primary patron of physics became state governments, who recognized that the support of "basic" research could often lead to technologies useful to both military and industrial applications. Currently, general relativity and quantum mechanics are inconsistent with each other, and efforts are underway to unify the two.
What is the answer to this question: What event was going on during the creation of the atomic bomb?
****
So... World War II

The problem: Answer a question about this article:
At the inception of the Premier League in 199293, just eleven players named in the starting line-ups for the first round of matches hailed from outside of the United Kingdom or Ireland. By 200001, the number of foreign players participating in the Premier League was 36 per cent of the total. In the 200405 season the figure had increased to 45 per cent. On 26 December 1999, Chelsea became the first Premier League side to field an entirely foreign starting line-up, and on 14 February 2005 Arsenal were the first to name a completely foreign 16-man squad for a match. By 2009, under 40% of the players in the Premier League were English.
In 2009, what percent of the players were English in the Premier League?
****
The answer: By 2009, under 40% of the players in the Premier League were English.

Problem: Please answer a question about the following article about Myanmar:
Typical jungle animals, particularly tigers and leopards, occur sparsely in Myanmar. In upper Myanmar, there are rhinoceros, wild buffalo, wild boars, deer, antelope, and elephants, which are also tamed or bred in captivity for use as work animals, particularly in the lumber industry. Smaller mammals are also numerous, ranging from gibbons and monkeys to flying foxes and tapirs. The abundance of birds is notable with over 800 species, including parrots, peafowl, pheasants, crows, herons, and paddybirds. Among reptile species there are crocodiles, geckos, cobras, Burmese pythons, and turtles. Hundreds of species of freshwater fish are wide-ranging, plentiful and are very important food sources. For a list of protected areas, see List of protected areas of Myanmar.
What industry is supported by animal labor in Burma ?
A: the lumber industry

Unfortunately, requiring two characters to mark the end of a line introduces unnecessary complexity and questions as to how to interpret each character when encountered alone. To simplify matters plain text data streams, including files, on Multics used line feed (LF) alone as a line terminator. Unix and Unix-like systems, and Amiga systems, adopted this convention from Multics. The original Macintosh OS, Apple DOS, and ProDOS, on the other hand, used carriage return (CR) alone as a line terminator; however, since Apple replaced these operating systems with the Unix-based OS X operating system, they now use line feed (LF) as well.

Why is adding two characters at the ned of a line problemsome?
Answer: introduces unnecessary complexity and questions as to how to interpret each character when encountered alone

Some species of marine animals exist and rely, directly or indirectly, on the phytoplankton. Antarctic sea life includes penguins, blue whales, orcas, colossal squids and fur seals. The emperor penguin is the only penguin that breeds during the winter in Antarctica, while the Adelie penguin breeds farther south than any other penguin. The rockhopper penguin has distinctive feathers around the eyes, giving the appearance of elaborate eyelashes. King penguins, chinstrap penguins, and gentoo penguins also breed in the Antarctic.
What feature does the rockhopper penguin have around its eyes?
feathers
