【分析解答题】

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.

Select the sentence that mentions a specific moral dilemma resulting from the use of a memory-altering drug.
