This question assesses the ability to distinguish between the meanings of similar verbs. 'Predicts' is correctly used in option A, as it means to say that something will happen in the future, which aligns with the context of an experiment's outcome. 'Displays' (B) means to show, 'proves' (C) means to demonstrate the truth or existence of something, and 'discovers' (D) means to find something for the first time, none of which fit the context of forecasting an experiment's result.
