Final answer:
Comparative adjectives and adverbs are used to show differences, as in the statement 'Soccer is more continuous than football,' which compares the flow of play in the two sports.
Step-by-step explanation:
The comparative forms of adjectives and adverbs are used to compare differences between the two things they modify. In the context of soccer and football, one could say: "Soccer is generally more continuous than football, as football often has longer breaks between plays." Here, "more continuous" is a comparative adjective modifying soccer, and "longer" is another comparative adjective comparing the duration of breaks in football to those in soccer.
