Wait, what's the difference between float before production and queue time? I'm not sure I fully understand how those fit into a routing operation. I'll have to guess on this one.

I'm a bit unsure about this one. The options seem pretty similar, but I'll go with proportionate since that seems to fit the legal requirements mentioned in the question.

This seems like a straightforward question about improving a machine learning model. I'd start by looking at the performance metrics in Stackdriver and analyzing them in BigQuery to identify areas for improvement.

I'm a bit confused on this one. I'll have to review the material again to make sure I understand where the loadbalancing mode is specified.

Block hashes? Isn't that like using the weather to predict the stock market? I'll stick with the oracle, thanks.
