问题 It sounds like the premise for a science fiction novel, but scientists are today developing a drug that could eliminate traumatic events from our memories. Thus far the research is focused on altering memories immediately following one particular type of trauma, car accidents, with promising results. But the potential applications of the research are far more wide reaching and morally ambiguous. On one hand, such a drug could provide a breakthrough in the treatment of post-traumatic stress disorder in war veterans and rape victims. On the other hand, by relegating our memories to oblivion, such a drug could fundamentally change our sense of self and personal history. It is unclear how the human brain stores memories, and much is unknown about why painful memories of traumatic events come back to haunt some and not others. But one thing is certain—as research into the technology of altering memories continues, so will the ethical debates on whether this pharmaceutical innovation falls outside the spectrum of appropriate medical interventions.
It can be inferred from the passage that
选项 A、scientists have discovered a means by which human memories can be completely eliminated
B、only drugs that affect memory are morally ambiguous
C、ethical debates are a predictable result of certain types of scientific research
答案C
解析 The best answer is C only. According to the passage, one thing is certain: debate will continue in this field. Therefore, it is implied that ethical debates are a predictable result of certain types of medical research.
