C. Read the passage and answer the questions given below.
Since the advent of the internet, there have been profound changes in the way we live, work or play. Firstly, the internet has brought e- mail to the masses, which made it possible to send messages, digital photos, music, and videos to anywhere in the world instantly. Gone 'are the days when it took about fifteen days for a letter from Lahore to reach San Francisco. Besides e- mail, further innovations like instant messaging has also become the norm. With a web camera, users can actually see each other on the computer monitor and speak to each other through a microphone at no extra cost. In the past, this convenience was only available to companies that could afford highly expensive video conferencing equipment at exorbitant charges. The effect of this technological development is that people are able to stay in close touch with each other even though they are thousands of kilometres apart. Not long ago, this was only possible in science fiction movies and our fantasies. Internet has also changed the way we access information. In the past, one had to search books, magazines and libraries if one needed to know something. Now, search engines e.g. Google and Yahoo give us a list of websites that provide the information that we need. There are even free online dictionaries, encyclopedias and maps. As technology advances, the impact of the internet will be even more profound in the future. Now it is up to us to use its power to serve mankind in a positive way.
