1. Have you heard of Sir Charles Babbage? He is often as the “Father of the Computer” because of the computer he in the 19th century. Computers are one of the most important tools in , but Babbage’s name is not so well-known. He was an English mathematician and , and he lived from 1791 to 1871. He wanted to design a that could do math with fewer mistakes than humans. He couldn’t finish it, but in 1991 the Science Museum in London used his to create a . Amazingly, Babbage’s design produced a computer that worked.

Eight hundred years ago, a man in southern Turkey invented an amazing clock. It was more than 23 feet (seven meters) high. At its base was a life-size model elephant. Every half hour, something amazing happened. The whole clock came alive: Model birds, dragons, and people started to move. The clock’s inventor was an engineer named al-Jazari. He lived in Diyarbakir, a city in Turkey. Al-Jazari was probably one of the greatest engineers in history. Some historians call him “the father of modern-day engineering.”
We know about al-Jazari mostly from a book that he wrote. It describes a number of machines of all shapes and sizes. They include clocks, hand-washing machines, and pumps for lifting water. The book also has drawings that show how each machine works. Many everyday items today – from toys to car engines – still use al-Jazari’s ideas. Without his machines with moving parts, we might not have modern-day robots.
Bill Gates is sometimes called “the father of home computing.” Born in 1955, Gates grew up in the United States. When he was 13, his school bought one of the earliest computers, and Gates showed huge interest in it. After discussing it with his teachers, he was allowed to miss math class and instead spend time on the computer. His aim was to be able to write his own computer programs. Gates became not just a brilliant computer programmer but also a smart businessman. In 1975, before he finished university, Gates co-founded Microsoft. As the company became successful, Gates had no reason to finish his university studies. In 2015, the company celebrated its 40th birthday and is now the world’s largest computer software company.
Ada Lovelace was born in 1815 and grew up in London, England. As a young girl, she was brilliant at math and science. At the age of 13, she even created a design for a flying machine.
When she was 17 years old, Lovelace met a mathematician named Charles Babbage. They became friends and enjoyed discussing math together. At the time, Babbage was working on a design for a machine called an “Analytical Engine.” The machine would be able to work on difficult math problems. Lovelace was very interested.
In 1843, Lovelace helped write an article on the Analytical Engine. She added her own ideas and notes to it. One of her notes described a step-by-step calculation that the Analytical Engine could perform. Today, the Analytical Engine is thought to be the first design of what we now call a computer. And Lovelace’s step-by-step calculation is thought to be the first ever computer program.

Pregunta 4 of 12
4. Pregunta
A
Sometimes people discover things or invent products by accident. Then they can’t find a way to use their invention, so they don’t think it’s important. Later, however, someone else may realize how to make the discovery useful. The “Post-it Notes” that you probably have in your home or office right now are a good example of this.
B
In 1968, a scientist was doing research at a large company called 3M. His goal was to create a very strong glue to stick things together. Instead, the glue he made was weak and not very sticky, and he thought it was a failure. He told his coworkers about his discovery, but none of them could think of any way to use it. Six years later, in 1974, another person at 3M had an idea. He put some of the weak glue on a piece of paper and used it to mark the page he was reading in a book. When he removed the piece of paper, it came off easily and didn’t make the page sticky. Best of all, he could use it again and again. He had found a good use for the weak glue.
C
This time 3M liked the invention, and in 1977 it began to give samples of the small, sticky paper to shoppers. The company called their product “Post-it Notes.” When the shoppers tried Post-it Notes, they loved them. They quickly discovered many uses for the small squares of paper, and most of them said that they would use Post-it Notes again. 3M realized it had a great product, and these days, people from all over the world use them all the time.
Read the passage. Then look at the statements and write in CAPITAL LETTERS:
TRUE if a statement is the same as information in the passage
FALSE if a statement is different to information in the passage
NOT GIVEN if there is no information about this in the passage
