You could write a totally persuasive argument that simply consists of your own ideas and theories and logical connections.

你可以写一个完全有说服力的论点，简单地由你自己的想法、理论和逻辑联系组成。

In the original problem, the rules seemed more arbitrary, and when they’re abstracted that way, the logical connections become harder to see.

在最初的问题中， 规则似乎更随意，当它们以这种方式抽象时，逻辑联系变得更难看清。

So what that means is you're going to have to understand the main idea of the passage in order to figure out and make that logical connection to understand the answer.

这意味着你必须了解段落的中心思想，以便弄明白意思并与之建立逻辑联系，从而理解答案。
