Without emotion, we can deliberate for hours, weighing the pros and cons, but we'd be unable to come to a decision.

没有情绪，我们可以思考几个小时，权衡利弊，但我们无法做出决定。

I'll be talking and they'll be weighing the pros and cons, right?

我会说话，他们会权衡利弊，对吗？

The same way that I make all the important decisions in my life, by weighing the pros and cons of both schools.

就跟做出人生中其他重大决定一样，权衡两所学校的利弊。

You may be weighing the pros and cons of that decision and in doing so you might say I'm of two minds on whether I should take this promotion.

您可能正在权衡该决定的利弊，在权衡的过程中，您可能会说，我对是否应该接受这次晋升犹豫不决。
