Organize os parágrafos a seguir numerando os parênteses em ordem crescente, conforme a cronologia dos fatos. Para auxiliá-lo (a), o título do texto já está marcado. Não se esqueça de utilizar as ferramentas que aprendeu até agora, como também de observar as palavras conhecidas e os recursos tipográficos (números que indicam data, ano, tempo etc.). Tudo isso facilitará a sua compreensão.

1. () In 1930, Vannevar Bush built the first analog computer, which was used to help aim guns in World War II. In the period between 1938-1942, John V. Atanasoff and Clifford Berry designed and built the first electronic digital computer, the ABC, which provided the basis for the development of the ENIAC.
2. () In 1822, Charles Babbage built a machine called "The Difference Engine," which he showed at The Paris Exhibition in 1855. During the same period, Lady Ada Lovelace invented an arithmetic code for Babbage's machine based on a binary system similar to the one used with modern computers. For this reason, she is considered to be the first programmer.
3. () The modern computer as we know it today is a result of lots of research and inventions of the past. The following paragraphs will show you the evolution of this miraculous machine.
4. () In the period called the Scientific Revolution, which began circa 1540 and lasted until 1687, many scientists tried to find ways of calculating. As a consequence, other computational devices were invented. In 1642, Blaise Pascal invented the first mechanical calculator. In 1673, Gottfried von Leibniz invented another calculating device.
5. () The Scientific Revolution was followed by the Industrial Revolution, which started in England and brought many advances in technology. Several machines were developed in this period, and these machines later had a great impact on the development of computers.
6. () The Pre-History of Computers
7. () Between 1943 and 1946, funded by the U.S. Army, John Mauchly and J. Eckert built the first major eletronic digital computer using vacuum tubes. The ENIAC (Electronic Numerical Integrator and Computer) was huge and weighed about 30 tons.
8. () The developments which took place during World War II led to the advances made in the period that followed the war. The period after the war led to the subsequent generations of computers, which may be described as the modern age of computers.
9. () In 1944, Howard Aiken and some engineers from IBM completed MARK 1, an electro-mechanical calculating device controlled by punched cards. This first digital computer could figure out long lists of mathematical problems and was used military ballistics.
