What's the error in "Either he or I is right"? [closed]

Solution 1:

Either he or I am right is the answer.

The subject-verb agreement rule for either...or and neither... nor says that the verb will agree with the subject that is closest to it. Proximity of the subject to the verb is the only thing that matters when it's a question of either...or or neither ...nor.

Some may argue that even Either I or he(closest subject) is(verb) right is correct, but I think it's better to put he before I.(There is a name for this rule that I cannot recollect, it's called some 'donkey' rule.)
