I knew what the answer was, and thought that "The maximum Tax Rates across all State/Province IDs" described it well. I supopose I should have read more closely and realised that "The maximum Tax Rates per State/Province ID" also described it well, then tried to work out the difference between the two statements. Though I'd probably have picked the wrong one anyway.Should it have said "The maximum Tax Rate [singular] across all State/Province IDs"?
I was lucky. I didn't look at all the answers, just went for the first one that was obviously correct. If I'd read the other one, I would have had great difficulty deciding what the difference was supposed to be and ended up with only an even chance of getting it right because to me those two answer options mean exactly the same. Now if the second had used singular instead of plural it would indeed have meant something quite different and been wrong, but as it stands I believe they both mean the same and both are correct.
