To confirm, is "a man, a dog, and a cat" considered singular or plural?
Posted from my mobile device If we consider that "what" is used to replace "things that", then we can probably reach a conclusion:
Correct:
Things that are interesting to note are that GMAT scores can be cancelled, that cancelled GMAT scores do not show up on official GMAT reports, and that cancelled GMAT scores can be reinstated.... correct.
( The first verb ARE is the verb of the relative clause that starts with "that"; "that" refers to "things" and hence the first verb (within the clause) should be plural. The second verb ARE is the main verb of the sentence whose subject is directly "things", hence the second verb ARE also should be plural.)
A thing that is interesting to note is that GMAT scores can be cancelled, that cancelled GMAT scores do not show up on official GMAT reports, and that cancelled GMAT scores can be reinstated... wrong (A thing cannot be 3 things)
With this reasoning, I would say the following would be correct:
What are interesting to note are that GMAT scores can be cancelled, that cancelled GMAT scores do not show up on official GMAT reports, and that cancelled GMAT scores can be reinstated.
