Final answer:
The correct verb form to use with 'none' depends on whether it refers to a singular or plural noun. 'Was' is used for singular or uncountable nouns, while either 'have' or 'has' can be used for plural nouns depending on the regional variation of English.
Step-by-step explanation:
The correct verb form to use with none in a sentence depends on the context in which none is used. If none refers to none of a singular noun or an uncountable noun, it should be followed by a singular verb. For example, if the sentence is 'None of the information was correct,' the correct verb to use is 'was.' On the other hand, if none refers to none of a plural noun, it can be followed by either a singular or a plural verb depending on the preferred style (British or American English) and the implied meaning. For instance, 'None of the students have (American English often prefers plural) / has (British English often prefers singular) received their certificates' is correct.
