Is there still a chance it will be saved?
I was rescued by the relationship advice that my teacher Koichi gave me.
"So, are we going out or what? Make it clear!" "Um…" (The front doorbell rings: ring-ring.) "Phew, saved by the bell."
You know that 助ける means "to help" - so, this is a different version of that. This is when someone is helping someone else, or something is helping you, but you're not doing the action of helping someone. Use the か to help you remember: The "car" helps you to drive around. That's why this word means to be helped.
It also can be used to talk about how you were rescued, which is like being helped, right? If you want to memorize it that way, that's fine too.
The reading is the same as 助ける, so hopefully you know that word and can apply that knowledge over here.
