Embarrassment over the discovery of ( element 118,announced with great fanfare and then retracted amid accusations of scientific fraud,has left ) the nuclear physics comminity feeling bruised.
A.element 118,announced with great fanfare and then retracted amid accusations of scientific fraud,has left
B.element 118,which was announced with great fanfare and afterwards which was retracted amid accusations of scientific fraud,has left
答
选A,插入句正确形容主语“embarrassment”.
在B中,PARALLEL STRUCTURE出错,多余,并改变原句意思,不该有的第二个"which"错误指代之前的"great fanfare",但是作者可能意指的是EMBARRASSMENT.
