Question

The following passage is from the opening of the science fiction short story “The Star,” by H. G. Wells. In the remainder of the story, an astronomical event pulls another planet into the center of our solar system. Read the passage. Then, answer the question(s). (1) It was on the first day of the New Year that the announcement was made, almost simultaneously from three observatories ... the motion of the planet Neptune, the outermost of all the planets that wheel about the sun, had become very erratic.... Such a piece of news was scarcely calculated to interest a world the greater portion of whose inhabitants were unaware of the existence of the planet Neptune, nor outside the astronomical profession did the subsequent discovery of a faint remote speck of light in the region ... cause any very great excitement. Scientific people, however, found the intelligence remarkable enough, even before it became known that the new body was rapidly growing larger and brighter,... (2) By the second day it was clearly visible to any decent instrument, as a speck with a barely sensible diameter, in the constellation Leo near Regulus. In a little while an opera glass could attain it. (3) On the third day of the new year the newspaper readers of two hemispheres were made aware for the first time of the real importance of this unusual apparition in the heavens. “A Planetary Collision,” one London paper headed the news, and proclaimed [the] opinion that this strange new planet would probably collide with Neptune.... [I]n most of the capitals of the world, on January 3rd, there was an expectation, however vague of some imminent phenomenon in the sky... (4) And in a hundred observatories there had been suppressed excitement, rising almost to shouting pitch, as the two remote bodies had rushed together…. There was a hurrying to and fro, to gather photographic apparatus and spectroscope, and this appliance and that, to record this novel astonishing sight, the destruction of a world. For it was a world, a sister planet of our earth,… that had so suddenly flashed into flaming death. Neptune… had been struck, fairly and squarely, by the strange planet from outer space…. Part A Which theme would most likely be developed in the story? Base your answer on the introduction and the details in the passage. A. Knowledge is important to humanity's survival. B. Space travel is a dangerous but necessary mission. C. Newspapers can create panic by printing incorrect information. D. Human life is unimportant compared to the rest of the universe. Part B Which details from the selection best support the answer to Part A? A. descriptions of the public reaction to the event B. descriptions of scientists rushing to and fro C. descriptions of how the planet's appearance changes over time D. descriptions of how people use science to discover danger
