Duke Kahanamoku promoted the sport of surfing as well as popularized it.


Duke Kahanamoku popularized the sport of surfing as well as promoting it.


Duke Kahanamoku promoted not only the sport of surfing but also popularized it.

Answer 1

Duke Kahanamoku promoted the sport of surfing as well as popularized it.

Answer 2

The correct answer is: Duke Kahanamoku promoted the sport of surfing as well as popularized it.

This sentence is parallel because the two actions -- or verbs -- are in the same form: promoted and popularized.

Any sentence that uses promoted/popularizing OR promoting/popularized is incorrect. These verbs need to be in the same form -- either both must end in -ed or both must end in -ing.
