What is Coinbase earn quiz?

I'm curious, can you explain to me what the Coinbase Earn Quiz is? I've heard it's a way to learn about cryptocurrencies and potentially earn some as well, but I'd like to get a better understanding of how it works. Is it just a simple quiz that rewards users with crypto for answering questions correctly, or is there more to it? I'm eager to learn more about this opportunity and see if it's something I could benefit from.
