Flair - when somebody does something with what seems natural talent. Doing something amazing
David Copperfield has a flair for captivating illusions
People can have a flair for drama, style, humor.
A knack.
Having a flair for style would mean you were not poorly dressed as a non-example.
People that practice really hard to the point of proficiency will appear to have a flair for the thing they have practiced.
Sorry for the disjointed thought stream in this post, I apparently lack the flair of organized thought today.
Hm, are you sure you got the question right? Because all of the sentences are written in active voice! Active voice is essentially everything that is not in the passive voice, and I don't see any passive voice here.
Passive voice would be formed with subject+form of "to be" + past participle,
and we have no example of this. All of the sentences here are in active voice.
