An ordinary man... an extraordinary business
Ben Silbermann was an ordinary boy. He was born in 1982 in Iowa in the USA and he loved collecting things: stamps, leaves, and especially insects. As a young man in his 20s, his love of collecting became big business.
He went to Yale University and studied chemistry and political science. In 2006, when he graduated from university, he moved to the state of California and got a job at Google. Silbermann met a lot of people there who were very interested in technology, and he decided two things: he wanted to start a business and he wanted to do something he loved.
He worked at Google for two years. Then, in 2008, Silbermann left his job and he started his own business with two friends: Paul Sciarra and Evan Sharp. In November 2009, they got an apartment together in Palo Alto, California and started work on Pinterest. Silbermann and Sharp realised they both loved collecting, and they made a “virtual pinboard” - pages online where you “pin” pictures of things you like and things you “collect”. Their idea was to connect everyone in the world through the things they find interesting.
And it seemed that a lot of people liked their idea. When Pinterest started in March 2010, it grew quickly and had 10 million users after the first year. This was an amazing number compared with Twitter and Facebook: Twitter took two years to reach 10 million users and Facebook took over five years. Just a year after starting, Pinterest was worth $200 million and had over 421 million page views. Silbermann’s ordinary interest as a boy certainly became an extraordinary business.

The Magical Mind of Leonardo Da Vinci
When someone shows great skills in a certain field, we call them a genius. In particular, the term is most associated with two people. One is the famed scientist Albert Einstein, and the other is Leonardo Da Vinci. However, unlike Einstein, whose achievements were essentially all related to science, Leonardo Da Vinci was a master at art, architecture, invention, and several other areas.
Da Vinci was born in Italy in 1452. He took to art at an early age and at age 14, he went to study as an apprentice in Florence under the artist Verrocchio. For the next six years. Da Vinci picked up drawing, carpentry, sculpting, and many other techniques from his master and his talent was evident. In fact, Da Vinci was such a good painter that his talent frustrated his master. Eventually, Verrocchio was so frustrated by his student’s genius that he stopped painting altogether. By the age of 20, Da Vinci was considered a master artist and set up his own workshop. It was there that Da Vinci was approached to create a painting for the Duke of Milan. The Duke was so impressed by his work that he would bring him under his service. In addition to creating paintings and sculptures, the Duke also had him design innovative buildings, machines, and weapons. Da Vinci would draw up plans for several futuristic inventions including tanks, submarines, and flying machines. He also mastered the art of drawing every muscle and detail of the human body. The only criticism one could make of Da Vinci is that his brilliant mind jumped so quickly from subject to subject that he rarely completed the works he started. The ones he did finish were often spectacular masterpieces, such as his paintings The Last Supper and the timeless Mona Lisa. The latter, which is on display at the Louvre in Paris, is arguably the most famous painting of all times because of its incredible detail and realism.
Although Da Vinci died in 1519, his effect on the art world has never waned. He helped coin the term “Renaissance man” which refers to someone who excels in many different areas. Perhaps the greatest present Da Vinci left behind was his journals. Admirers and students of his work can examine 13,000 pages of his notes, drawings, and ideas to better understand what made this genius tick.
1. How is Einstein different from Da Vinci?
	A. He was much more intelligent. 	B. He was a slightly better painter
	C. He lived many years before Da Vinci. 	D. He mainly specialized in one subject.
2. Why did Verrocchio retire from painting?
	A. He found another way to make more money.
	B. He needed to spend more time instructing Da Vinci.
	C. He knew that he would never be as talented as Da Vinci.
	D. He was offered a job working for the Duke of Milan.
3. Which of the following best describes Da Vinci’s plans while working for the Duke of Milan?
	A. They were ahead of their time. 	B. They were common and predictable.
	C. They were all related to painting. 	D. They were easily put into action.
4. What could replace the word “waned” in the third paragraph?
	A. increased	B. decreased	C. stayed the same 	D. made people angry
5. In the second paragraph, what does the phrase “The latter” refer to?
	A. Da Vinci’s paintings	B. Mona Lisa
	C. The Last Supper	D. The final years of Da Vinci’s career
6. The word “coin” in the third paragraph is closest in meaning to ________.
	A. invent a new phrase	B. make coins out of metal
