Read the passage and choose the correct answer to each of the following questions.

Computers are machines that can help uss in many ways. However, they can’t think or do things on their own. Humans have to feed them with information and tell them what to do with it. They can’t come up with any new information. However, they can save a lot of time. For example, all the information and the office files can be stored in a computer’s “memory”. If a clerk were to trace any information from a particular file, the computer would only take some seconds to find It. It would take a clerk days or even weeks to go through every file if no computers were used.

The first computers were huge and costly. They filled up almost the whole floor of large offices. Later, because of the usefulness and demand for computers in business, scientists soon found ways to produce cheaper and smaller computers. They invented chips which made it possible to store more information.

Today, computers are not only cheaper but also more compact. They can be carried from place to place easily. Computers can be used in offices by companies, and they can be also used at home, by families who can afford them.
