Here is my sentence:
The report further identifies two partial sets, which are not in themselves default sets but which one can—wholly or partly—combine with default sets A or B, or indeed with any permutation of options.
Should that have been "set A or B"? Is the set singular or plural?
Here is a simpler sentence on (I believe) the same principle:
When you reach customs, depending on whether you are a citizen, join queues A or B.
One could reword the latter sentence to evade the question, of course, but I seek an answer rather than a way to avoid an answer.
The second sentence is just something I made up for this question, but here is part of a third sentence, which comes from the same report as the first:
[It] earns exactly one of the adjudications respectively of Tables 3, 4, 5 or 6.
Should that be Table rather than Tables? Should that be and rather than or?
(Extra appreciation is given if you can provide a reference for your answer or, better, can quote a great writer to illustrate. If you cannot but still know the answer, though, please still give it. My copies of the AP Stylebook and the Little, Brown Handbook do not seem to answer the question.)
