Answer:
When I first started to learn how to ride my bike it was scary and I fell and scraped my knees a lot.
Then my dad supported me until I was able to ride on my own and that was nice to have my dads support
Then finally I am able to ride hands-free, down a hill, at breakneck speed.
The pronoun that correctly completes the sentence is the pronoun "Who". So the complete sentence would be: "About who was the article written?" We used the pronoun "who" because it is used as the subject of the sentence, therefore a subjective pronoun should be used. The "whom" pronoun is an objective pronoun and should be used only as a direct object.
