问题     When a medical procedure or technology first comes onto the scene, it is almost invariably met with controversy from all sides regarding the way it can, and should, be applied. The ongoing debate over abortion is certainly no exception, a contentious issue that has captured the attention of laymen and medical practitioners alike for decades. With the introduction of the French "abortion pill" RU-486, the situation has become an even more urgent one to proponents on both sides of the issue. Those in favor of a woman’s right to choose abortion argue that the pill indicates that, whether we like it or not, the means to accomplish the goal is out there, and we must respond or be left behind. Anti-abortion activists, however, see the pill as representing the greatest threat to their cause to date, and thus a development that urges all to mobilize for the fight against abortion.
    The RU-486 "abortion pill" has already been used in over 200,000 recorded instances in France, claiming a 95.5% effectiveness rate when used in the first 7 weeks of pregnancy. In France, it is seen as a more economical and safer alternative to surgery, which was the method by which abortions were performed prior to the development of the pill. Recent studies have discovered that the pill may have beneficial side effects as well, including use as a promising treatment for breast and ovarian cancer, glaucoma, adrenal cancer, and a host of other illnesses.
    Although generally considered safe for use, the use of the pill has not been without complications, most notably exemplified in the case of one French woman who died of a heart attack after ingesting the proper dosage of the medicine. Further, due to its relatively short history, the long-term effects of the RU-486 drug have yet to be conclusively examined. This and other concerns, including political ones, have prevented such states as Canada and the United States from approving the use of the pill within its borders. Other states have been undeterred, however, as a host of other nations currently use the pill as a viable method of abortion in some form or another.
    The underlying issue is one that goes beyond the use of the RU-486 pill, however, extending to the question of morality. Activists opposed to abortion, including the Catholic church, viewing life as beginning at conception, and thus abortion is a form of murder in every case. Those in favor of abortion see life as a process beginning at birth, thus equating abortion procedures to any other standard medical treatments. Until those deeper levels of contention are resolved, the issue of "the pill" will be one of only marginal importance.
From Paragraph 3, we learn that______.

选项 A、the use of the RU-486 pill is unsafe
B、the RU-486 abortion drug is unlikely to spread in use to other countries until more extensive tests are performed
C、although the track record is generally positive, some recorded effects of RU-486 warrant further study
D、health considerations are currently the main factor hindering efforts to expand drug-induced abortions

答案C

解析 属信息推断题。第三段第一、二句说:虽然普遍认为使用人流丸是安全的,但人流丸的使用并不是没有引起并发症……。RU-486“人流丸”的历史相对较短,它的长期影响还有待验证。由此可知,选项C正确。选项A与第一句意思不符;选项B、D都与第三句内容不符,影响“人流丸”使用范围的因素除疗效外,还有来自政治等方面的担心。
