I can tell you what it's not if you're having trouble understanding parallel structure...
"I think I will make a good president because I am honest, trustworthy, and I’m behaving responsibly.<span>"
If this was using parallel structure, it would be "...</span>because I am honest, trustworthy, and responsible."
"<span>I have many plans for the student council, such as making the council more organized, to ensure everyone has a voice, and I’ll be managing meetings more efficiently."
</span>For this, it'd have to be, "...such as making the council more organized, ensuring everyone has a voice, managing meetings more efficiently."
I'm not sure which sentence it actually is though. It's possible it's the last sentence.
