question 213

Multiple Choice

In 1958, the magazine Popular Science predicted that the "age-old dream of flying like a bird may be closer than we think." How was this supposed to come to pass? The magazine predicted that people would be flying around with the greatest of ease using rocket-powered jetpacks. Indeed, such means of locomotion exist today. But there are many hurdles to pass before they become widely used. They are literally rockets, so they make a terrible racket-up to 130 decibels, which is actually louder than a 747 at takeoff. They're heavy, too. At eighty-five pounds, they're far too heavy for use by the majority of the population today. Finally, they're extremely costly. Entry-level jetpacks go for around a quarter of million dollars. And prices soar upwards from there. So while personal jetpacks are a great idea in theory, reality will prevent them from becoming a viable source of transportation anytime soon.
Which of the following key ideas is true according to the passage?

• A)People once believed that jetpacks would be widely used someday.
• B)They can propel a user through the air faster than a 747 at takeoff.
• C)The cost of rocket-powered jetpacks has gone down recently.
• D)They use a power source similar to that of a modern locomotive.
