Three men traveling on a train began a conversition about the world's greatest wonders.
“ In my opinion,” the first man said, “ the Egyptian pyramids are the world’s greatest wonder. Although they were built thousands of years ago, they are still standing. And remember: the people who built them had only simple tools. They didn’t have the kind of machinery that builders and engineers have today.
“ I agree that the Egyptian pyramids are wonderful,” the second man said, “ But I don’t think they’re the greatest wonder. I believe computers are more wonderful than the pyramids. They have taken people to the moon and brought them back safely. They carry out mathematical calculations in seconds that would take a person a hundred years to do.”
