When "None of+ plural" is plural?

[rajendraprasad1984]

Hi,

As per Manhattan SC Guide, SANAM pronouns (Some, Any, None, All, More/Most) can be either singular or plural depending on the context of the sentence. It says one should look at the noun object of the Of-phrase to determine the number of the subject.

Ex: Some of the money was stolen.
Some of the documents were stolen.

But How to determine the number with None?

SC Question 22 from OG-12 says "None of the attempts to specify the causes of crime explains". Here the number is singular. Why it is not plular here?

When it is plural and when it is singular?

Hi, take a look here.
