- USB 3.1 Gen 2 is the same as USB 3.2 Gen 2 and is only found at 10Gbps.
- The 40Gbps entry is wrong, the real spec name is USB4 Gen 3x2. But it was never really advertised as such so I'd leave that out.
- 20Gbps is either USB 3.2 Gen 2x2 or USB4 Gen3x1, but I'd caution against adding this as the latter is quite rare to see (plus the above reason).
For the quiz, I would split up connecting storage devices and PCIE enclosures. Most storage only goes up to 10Gbps, and it will specifically say if it's built for Thunderbolt.
The USB versioning table needs some corrections:
