Questão 96585

Examine the following statements concerning the use of 'neither' with subject-verb agreement:

I. In the phrase 'Neither the manager nor the employees...', the verb that follows must agree with the closest subject, 'employees', and therefore must be plural.
II. When 'neither' is used as a pronoun, as in 'Neither of the reports is complete,' it is treated as singular and requires a singular verb.
III. The sentence 'Neither he nor I am responsible' is considered grammatically correct in contemporary informal English, although formal usage would prefer 'am responsible.'

Based on a rigorous analysis according to formal grammar rules, which statements are correct?
