急:提问一道GRE填空
Read’s apology to Heflin was not exactly abject and
did little to _____their decades-long quarrel, which had been as _____ as the
academic etiquette of scholarly journals permitted. AE/AF



Blank (i)



Blank (ii)





A resolve



D sporadic





B encourage



E
courteous





C blur



F acrimonious


请问which指代谁?为何E不行,用来表示apology的礼貌程度?

楼上说的对,acrimonious基本是academic etiquette of scholarly journals permitted的对应词
再问： etiquette是礼节，礼仪的意思啊，跟争吵有什么关系
