Dr. Kim: Electronic fetal monitors, now routinely
used in hospital delivery rooms to check fetal
heartbeat, are more intrusive than ordinary
stethoscopes and do no more to improve the
chances that a healthy baby will be born.
Therefore, the additional cost of electronic
monitoring is unjustified and such monitor-jog
should be discontinued.
Dr. Anders: I disagree. Although you and I know
that both methods are capable of providing the
same information, electronic monitoring has been
well worth the cost. Doctors now know the warning
signs they need to listen for with stethoscopes,
but only because of what was learned from using
electronic monitors.

看不懂   Doctors now know the warning
signs they need to listen for with stethoscopes,
but only because of what was learned from using
electronic monitors.  这句话什么意思？ 有谁帮助翻译一下？

番茄炒蛋

doctor因为有了Electronic fetal monitors以后才知道了warning
signs they need to listen for with stethoscopes
但是这个题有一个逻辑上的问题就是，既然已经知道了，那么就没有必要再用Electronic fetal monitors咯，因为这个咚咚好贵啊
呵呵，你看完全题就知道了
