Read the following article. Then, answer the question(s). (1) It can be easy to take for granted the incredible computing power squeezed into today’s electronics. Compared to the first “computers,” today’s devices are as magical as Aladdin’s lamp. One of the first mechanical calculators, built in the 1600s, could work with eight digits, but had trouble carrying numbers because its gears tended to jam. In 1820 or 1821, Charles Babbage began working on a “difference engine”—a mechanical calculator designed to print astronomical tables. It is hard for us to imagine, but it was powered by steam. Today’s tiny batteries power handheld devices for hours on end.

(2) The first all-purpose electronic computer was unveiled in 1946. It was called ENIAC—the Electronic Numerical Integrator and Computer—and it weighed a monstrous 30 tons and occupied a 30-by-50-foot room. Funded for use in World War II, it was so large that it had power lines dedicated just for its use! Some people were nervous that the whole thing might blow up when it was turned on. It didn’t, and it proved to be very useful. Mathematical calculations that had previously taken 12 hours to do by hand could be completed in 30 seconds. Even so, the ENIAC’s computing power was less than that of today’s throwaway chips that play music in greeting cards! It is simply astonishing just how far technology has come in the last 75 years. Can you imagine what might happen in the next 75 years?

Announcer two: ladies and gentlemen, following on the news given in our bulletin a moment ago, the government meteorological bureau has requested the large observatories of the country to keep an astronomical watch on any further disturbances occurring on the planet mars. due to the unusual nature of this occurrence, we have arranged an interview with noted astronomer professor pierson, who will give us his views on the event. in a few moments we will take you to the princeton observatory at princeton, new jersey. we return you until then to the music of ramón raquello and his orchestra. the passage is from the transcript of the radio adaptation of the war of the worlds by h. g. wells. instead of including expert interviews, h. g. wells uses a narrator to tell about an alien invasion that occurred a few years earlier. by including expert interviews, how does the radio broadcast change the story most effectively? o.a. it puts the story in the past tense, increasing its personal tone. o o b. it makes the broadcast sound more like a fictional story. o o c. it makes the broadcast sound like a news report. o d. it makes the story sound less believable by changing who presents the story's details.
