一道高中英语单选，求翻译和详解

Question

The way they were talking __the problem seemed impossible.
A.about settling B.of settling C.to settle D.about to settle
答案是D，求翻译和详解

Answer 1

选项D中的不定式to settle表示将来的动作
settle the problem 是固定搭配“处理解决那个问题”的意思
此句中的“way”是“方法”的意思
翻译：他们正在谈论的关于解决那个问题的方法似乎行不通。

Answer 2

D 句意为他们所讨论的以解决此问题的方法似乎不现实.
The way (they were talking about) to settle the problem seemed impossible.
括号内为定语从句修饰the way, to settle the problem为不定式短语作后置定语修饰the way。
