How does the information in the listening passage add to the ideas presented in the reading passage?

In the paragraph we read, we were informed about the meaning of unintended, that these are unexpected effects or a decision you take, like not planned effects that may be positive or negative.

After that, the text introduced us to some legal terminology and gave us examples of positive unintended consequences for the citizen’s health.

Then, in the listening passage, the woman that spoke talks again of the meaning of unintended in the legal context, and gave an example of the raise of taxes and all the negative unintended consequences that that decision or change had made in the citizens and in the government and it’s initial plan of obtain more revenues.
