Answer:
I would say that the correct choice to fill in the blank in the question: The best way to make inferences is to combine background knowledge with:______, or the proof found in the details provided in the text, would be: Evidence.
Explanation:
An inference is precisely the conclusion, or the understanding, that you reach on something, given the details, the background and the evidence that is given to you. Without this, inferences would be devoid of veracity. But in order to make a good inference, a valid one, an analyst needs to first get some information, basic information, from a text, or discourse, to be able to reach such a conclusion. These pieces of information are: the background data, and most importantly, the evidence.
