Read the following passage and mark the letter A, B, C, or D to indicate the correct answer to each of the questions.

The advent of the Internet may be one of the most important technological developments in recent years. Never before have so many people had access to so many different sources of information. For all of the Internet’s advantages, however, people are currently becoming aware of some of its drawbacks and are looking for creative solutions. Among the current problems, which include a general lack of reliability and numerous security concerns, the most crucial is speed.

First of all, the Internet has grown very quickly. In 1990, only a few academics had ever heard of the Internet. In 1996, over 50 million people used it. Every year, the number of people with access to the Internet doubles. The rapid growth has been a problem. The computer systems which run the Internet have not been able to keep up with the demand. Also, sometimes, a request for information must pass through many routing computers before the information can be obtained. A request for information made in Paris might have to go through computers in New York, Los Angeles and Tokyo in order to obtain the required information. Consequently, the service is often slow and unpredictable. Service also tends to be worse when the Internet is busiest - during the business day of the Western Hemisphere - which is also when companies need its service the most.

Some people are trying to harness the power of networked computers in such a way as to avoid this problem. In 1995, a group of American universities banded together to form what has come to be known as Internet II. Internet II is a smaller, more specialized system intended for academic use. Since it is more specialized, fewer users are allowed access. Consequently, the time required to receive information has decreased.

Businesses are beginning to explore a possible analogue to the Internet II. Many businesses are creating their own “Intranets”. These are systems that can only be used by the members of the same company. In theory, fewer users should translate into a faster system. Intranets are very useful for large national and international companies whose branches need to share information. Another benefit of an Intranet is an increased amount of security. Since only company employees have access to the information on the Intranet, their information is protected from competitors. While there is little doubt that the Internet will

eventually be a fast and reliable service, industry and the academic community have taken their own steps toward making more practical global networks.

As it can be inferred from the passage, what benefits does Internet II have over the Internet I?

A. Small businesses pay higher premiums to access to the Internet

B. Internet II contains more information than the Internet.

C. Internet II has fewer users and therefore is faster to access

D. There is no governmental intervention regulating Internet II.

LESSONS FROM CURITIBA

Urban planning deals with the physical, economic, and social development of cities. Today urban populations are increasing rapidly, and growing cities are putting enormous pressure on the environment. For this reason, the type of urban planning found in Curitiba, in southern Brazil, is more important than ever.

Curitiba is a fine example of how urban planning can work. This has not always been the case, however. At one time, Curitiba faced the same problems as many other cities all over the world, namely overcrowding, pollution, and an increased demand for services, transport, and housing. How, then, did Curitiba address these problems?

By the 1940s the population of Curitiba had grown to about 150,000 as immigrants from countries such as Japan, Syria, and Lebanon came to work in agriculture and industry. These people needed both housing and transportation. Curitiba's leaders realised that it was not sensible to deal with these problems separately. Consequently, they employed a French planner and architect, Alfred Agache, to find an overall solution.

Agache studied all aspects of the problem. He designed a scheme which gave priority to public services such as sanitation and public transport. At the same time, the scheme included centres which helped both community life and commerce to develop, and reduced traffic congestion. This was the first scheme to address several problems of growing cities at the same time. Unfortunately, some parts of his plan were not completed. The result, as described below, was that his scheme only served Curitiba for another 20 years.

By the 1960s, the population of Curitiba had grown to about 430,000 inhabitants, so the city had to rethink its needs. In order to do this, the mayor put together a team of architects and town planners led by Jaime Lerner. This team produced the Curitiba Master Plan. This consisted of taking Agache's original plan and adding wide, high-speed roads which crossed the smaller streets. Their proposals also included plans to minimise urban growth, reduce city centre traffic, and preserve the city's historic district. It is clear that the Curitiba Master Plan was one of the first attempts to integrate all aspects of city planning.

This integrated approach to urban design was maintained throughout the 1980s as Curitiba's population grew to almost one million inhabitants. Environmental facilities were added, such as a recycling programme for household waste, and parks and 'green' spaces were protected from development. However, good transportation remained central to the planning.

Good transportation still remains a priority, together with the needs for jobs. A growing population needs employment, so business parks and centres have been added to encourage new small businesses. All these changes will continue be the population of Curitiba increases, but its city planners are continually searching for solutions to the problems.

How many problems are mentioned in the passage as commonly shared by many cities?

A. 2

B. 3

C. 4

D. 5
