The formula for inference is simply “text + background knowledge = inference”. This formula gives individuals a guide to help them use what they know and the text evidence to make a inference. Furthermore, it could lead to incorporate accountable talks as well as their background knowledge and text evidence to make a “logical” inference. However, if one is missing the background knowledge, he/she will not be able to make an inference even with the inference formula.
