Top 6 Unusual Guinness World Records Fastest 100 m running on all fours The 2008 Guinness World Records Day was, according to CWR, their biggest day of record-breaking ever, with more than 290,000 people taking part in record attempts in 15 different countries. Kenichi Ito's record attempt was part of this special day. He is just another example of Japanese with "super powers". His "super power" is to run with great speed on all fours. Kenichi Ito ran 100 m on all fours in 18.58 seconds. The Japanese set this record at Setagaya Kuritsu Sogo Undojyo, Tokyo, in 2008. Most people inside a soap bubble The Discovery Science Center in Santa Ana, California celebrated this year the 15th anniversary of the Bubble Festival. A bubble's math principles and science were presented and demonstrated at the three-week-long exhibition. The intriguing Bubble Show was also part of the program. Fan Yang and Deni Yang impressed the audience with their awesome skills for bubble making. The Yang family cooperated with the Discovery Science Center to set a new Guinness World Record for most people inside a soap bubble and they succeeded. The family that has been working with soap bubbles for 27 years created a huge soap bubble and got 118 people inside it. The record was set on April 4, 2011 Longest ears on a dog A bloodhound from Illinois has the longest ears ever measured a dog. The right ear is 13.75 inches long and the left one 13.5 inches. The dog named Tigger earned this title in 2004 and is owned by Christina and Bryan Flessner. Mr. Jeffries is the previous record holder of this title. Each of his ears measured approximately 11.5 inches long. His grandfather used to hold this amazing world record, but when he died Mr.Jeffries took over. Most living generations Did you ever wonder what is the Guinness World Record for most living generations in one family? Seven is the answer.

Read the following article and select the best answer. Article: Fish have ears. Really. They're quite small and have no opening to the outside world carrying sound through the body. For the past seven years, Simon Thorrold, a university professor, has been examining fish ears, small round ear bones called otoliths. As fish grow, so do their otoliths. Each day, their otoliths gain a ring of calcium carbonate . By looking through a microscope and counting these rings, Thorrold can determine the exact age of a young fish. As a fish gets older, its otoliths no longer get daily rings. Instead, they get yearly rings, which can also be counted, giving information about the fish's age, just like the growth rings of a tree. Ring counting is nothing new to fish scientists. But Thorrold has turned to a new direction. They're examining the chemical elements of each otolith ring. The daily ring gives us the time, but chemistry tells us about the environment in which the fish swam on any given day. These elements tell us about the chemistry of the water that the fish was in. It also says something about water temperature, which determines how much of these elements will gather within each otolith ring. Thorrold can tell, for example, if a fish spent time in the open ocean before entering the less salty water of coastal areas. He can basically tell where fish are spending their time at any given stage of history. In the case of the Atlantic croaker, a popular saltwater food fish, Thorrold and his assistant have successfully followed the travelling of young fish from mid-ocean to the coast, a journey of many hundreds of miles. This is important to managers in the fish industry, who know nearly nothing about the track of the young fish for most food fish in the ocean. Eager to learn about his technology, fish scientists are now lending Thorrold their ears. Question: How would you understand "fish scientists are now lending their ears"? - They are very interested in Thorrold's research findings. - They want to know where they can find fish. - They lend their fish for chemical studies. - They wonder if Thorrold can find growth rings from their ears.
(Answer)
They are very interested in Thorrold's research findings.

Read the following article and select the best answer. Article: As early as the mid-18th century, some people began raising doubts about Marco Polo's travels. In1995, historian Frances Wood argued in her bookDid Marco Polo Go to China? that the famous explorer from Venice never made it to pass the Black Sea. She noted that his travel journal left out the Great Wall of China,chopsticks and tea drinking among other details.Furthermore, Chinese documents from Polo's day made no mention of the explorer and his men. Wood and other scholars have argued that Marco Polo based his tales of China on information collected from fellow trades who had actually been there. Last year, a team of Italian researchers became the latest to challenge Polo's accounts . They said that evidence didn't support his description of Kublai Khan's Japanese invasions . Now, however, research by Hans Ulrich Vogel of Germany's Tubingen University might help prove Marco Polo was true. In a new bookMarco Polo Was in China,the professor of Chinese history tries to prove that Marco Polo spoke the truth. He suggests, for example, that Polo didn't include the Great Wall in his book because it only achieved its great importance in the Ming Dynasty several hundred years later. Vogel further explains that Chinese records from the 13th and 14th centuries avoided setting down visits from Westerners. Historians before him have touched on these issues. But Vogel also relies on another evidence:the explorer's very detailed descriptions of currency and salt production in the Yuan Dynasty. According to Vogel, Polo documented these aspects of Mongol Chinese culture in greater detail than any other of his time. This is a hint that Polo relied on his own powers of observation. Will we ever know whether Marco Polo traveled to China? Perhaps not, but the consequences ofhis real or fictional journey are still felt across the globe. One reader ofThe Travels of Marco Polowas Christopher Columbus, who stepped upon the New World while following his idol's footsteps. Question: France Wood doubted Marco Polo's travel's to China because his description _ . - missed some important culture of China - covered so much about traders' life - was full of obvious mistakes - seemed less detailed
missed some important culture of China
