问题 There was a lack of preparedness when the coronavirus arrived and that could be avoided had there been adequate medical resources.

选项 A、could have been avoided
B、would be avoided
C、would have been avoided
D、can have been

答案 A

解析 could have been done表示“原本可以做某事结果却没做”。句意：当冠状病毒到来时，人们缺乏准备。如果有充足的医疗资源，这种情况是可以避免的。请注意虚拟语气的条件句had there been应是if there had been的省略与倒装形式。
