问题    The first pre-election poll, or " straw vote" , as it was then called, was conducted by the Harrisburg Pennsylvanian before the 1824 presidential election. This straw vote and the many that followed it really registered nothing but local opinion. However, as communications improved and elections were won by closer and closer margins, newspapers and journals tried desperately to satisfy their readers’ curiosity in more reliable ways.
   Before the 1928 elections, no fewer than eighty-five publications made private inquiries, generally by means of questionnaires (问卷调查表) sent to subscribers (订户) and by telephone surveys. The principle common to all these inquiries was that they depended on quantity rather than quality: little effort was made to reach representatives of all segments (部分) of the population. Still, the erroneous belief persisted that the greater the number of questionnaires, the more accurate the results would be. The record was held by the American monthly Literary Digest, which sent out millions of postcards with short and pointed questions before each election, and received many hundreds of thousands of replies. In fact, in 1932, the forecast of Literary Digest was off by only 1 percent.
   In view of such striking achievements, it seemed rather impertinent (粗鲁的) for the young American journalist, George Gallup, to claim that large numbers were irrelevant, and that equally accurate or better predictions could be made with a small but carefully selected sample of the population and a small team of skilled interviewers.
   In 1936, it took Gallup a long time to convince thirty-five newspaper editors that his system was much cheaper than the customary mass inquiries and that it could provide surprisingly accurate predictions. The editors finally agreed, on condition that if Gallup’ s predictions were less accurate than those obtained by the tried method of the Literary Digest, he would have to refund (赔偿) the entire cost of the investigation. Although the Literary Digest broke its own record by obtaining two million replies to its electoral postcards that year, its prediction was wrong by 19 percent, whereas Gallup’ s was off by less than 1 percent.
From the passage we know that the earliest pre-election polls were______in reflecting the public opinions.
选项 A、meaningful
B、inaccurate
C、satisfying
D、successful
答案B
解析 推理题。根据文章第一段第二句可知，最初的选举前的民意测验反映的仅仅是地方性的、局部的意见，由此可以推断出，它在反映民意方面是片面的、不准确的，选项B(不准确的)符合文意。选项A(有意义的)、选项C(令人满意的)和选项D(成功的)都与原文意义相反。故本题选B。
