You can’t imagine what great trouble they have _____ the problem _____.

你想象不出在这个正在讨论的问题中他们有多么大的困难

从句中第一个空考察have trouble doing sth，干某事有困难，这个用what构成感叹句作主句的宾语

第二个空现在分词被动形式表示正在被讨论 的

希望对你有帮助，满意请采纳

选D 第一个空考查have trouble (in)doing 结构，第二个空考查过去分词的进行式作定语，表示“正在被讨论的（问题）”

You cant imagine what great trouble they have solving the problem being discussed.
