The question consists of two capitalized words that have a certain relationship to each other, followed by 4 pairs of words. Choose the pair that is related to each other in the same way as the capitalized pair
Subsequent means coming after something in time or following. Previous means existing or occurring before in time or order. These two are opposite in meaning. Inconsequential means not important or significant which is opposite to significant. Therefore 'Significant: Inconsequential' is the correct answer while the other pairs bear similar meaning.
