An inference is a conclusion or deduction made based on evidence and reasoning rather than from explicit statements or direct observation. It involves taking available information and reading between the lines to draw a logical conclusion.
For example, if you see dark clouds in the sky, you might infer that it might rain soon, even if no one has explicitly said it's going to rain.
So, an option that describes an inference would be something along the lines of: "A conclusion drawn from evidence and reasoning."
