But this specific part of the problem has a very clear solution.

但这一特定的问题有着十分清晰的解决方案。

And there's not always a solution – a clear solution.

而且并不总是有解决方案——一个明确的解决方案。

Like most problems related to the climate crisis there doesn't seem to be one clear solution.

像大多数与气候危机有关的问题一样，似乎没有一个明确的解决方案。

And reluctantly it seemed to me that the only clear and possible solution was that of Giraud — which Poirot despised.

不情愿地在我看来， 唯一明确和可能的解决方案是吉罗的解决方案——波洛鄙视这一点。
