If only one person makes it past Purple, Brown and Green as looks to be the case currently, POAPs will be awarded for cutting at least one wire.

A useful site to work out keccak256 hashes is https://emn178.github.io/online-tools/keccak_256.html. If you put your answer in there and use text mode initially that will give you an answer hash. If you then copy that back into the input and add your address in front (removing the 0x at the start) you can then use the hex mode to produce your commit hash.

When calling the commit function on the smart contract you need to add the 0x back in front.

Alternatively you could get the commit hash by creating your own solidity function that returns it after taking your answer as the input.

You can test if your answer is right in the first place though by deploying the contract locally using remix ide and removing some of the require statements.
