Problem: What's your favorite cartoon? It may be difficult for you to decide. But for pianist Lang Lang, Tom and Jerry is the best one. When Lang was two years old, he saw Tom play the piano. This was his first time to enjoy western music and this experience encouraged him to learn to play the piano. His talent at the keyboard has taken him from Shenyang to the world. Lang became a good piano student at three. Ever since, the boy has been doing better and better. In 1997, the 15-year-old boy studied at a famous American music college. Lang's performances are energetic. He is well-known for making facial expressions and moving around while playing the piano. The road to success has never been easy. Lang's father stopped his job to look after him, while his mother stayed in Shenyang to make money. But Lang thinks himself lucky and believes he should give something back. He has helped the children in poor areas a lot.

Problem: Penguin Books is a British publishing house. It was co-founded in 1935 by Sir Allen Lane, his brothers Richard and John, as a line of the publishers The Bodley Head, only becoming a separate company the following year. Penguin revolutionised publishing in the 1930s through its inexpensive paperbacks, sold through Woolworths and other high street stores for sixpence, bringing high-quality paperback fiction and non-fiction to the mass market. Penguin's success demonstrated that large audiences existed for serious books. Penguin also had a significant impact on public debate in Britain, through its books on British culture, politics, the arts, and science. 

Penguin Books is now an imprint of the worldwide Penguin Random House, an emerging conglomerate which was formed in 2013 by the merger of the two publishers. Formerly, Penguin Group was wholly owned by Pearson PLC, the global media company which also owned the "Financial Times", but it now retains only a minority holding of 47% of the stock against Random House owner Bertelsmann which controls the majority stake. It is one of the largest English-language publishers, formerly known as the "Big Six", now the "Big Five". 

The first Penguin paperbacks were published in 1935, but at first only as an imprint of The Bodley Head (of Vigo Street) with the books originally distributed from the crypt of Holy Trinity Church Marylebone. Only paperback editions were published until the "King Penguin" series debuted in 1939, and latterly the "Pelican History of Art" was undertaken: these were unsuitable as paperbacks because of the length and copious illustrations on art paper so cloth bindings were chosen instead. Penguin Books has its registered office in the City of Westminster, London, England.

Problem: From 1989 through 1996, the total area of the US was listed as 9,372,610 km2 (3,618,780 sq mi) (land + inland water only). The listed total area changed to 9,629,091 km2 (3,717,813 sq mi) in 1997 (Great Lakes area and coastal waters added), to 9,631,418 km2 (3,718,711 sq mi) in 2004, to 9,631,420 km2 (3,718,710 sq mi) in 2006, and to 9,826,630 km2 (3,794,080 sq mi) in 2007 (territorial waters added). Currently, the CIA World Factbook gives 9,826,675 km2 (3,794,100 sq mi), the United Nations Statistics Division gives 9,629,091 km2 (3,717,813 sq mi), and the Encyclopædia Britannica gives 9,522,055 km2 (3,676,486 sq mi)(Great Lakes area included but not coastal waters). These source consider only the 50 states and the Federal District, and exclude overseas territories. 

By total area (water as well as land), the United States is either slightly larger or smaller than the People's Republic of China, making it the world's third or fourth largest country. China and the United States are smaller than Russia and Canada in total area, but are larger than Brazil. By land area only (exclusive of waters), the United States is the world's third largest country, after Russia and China, with Canada in fourth. Whether the US or China is the third largest country by total area depends on two factors: (1) The validity of China's claim on Aksai Chin and Trans-Karakoram Tract. Both these territories are also claimed by India, so are not counted; and (2) How US calculates its own surface area. Since the initial publishing of the World Factbook, the CIA has updated the total area of United States a number of times.
