Question

Most of the factual information are wrong . Some of it at the most elementary level.
Identify the error

Answer 1

instead of 'are' there should have been' 'is'

and cut off 'most'

Answer 2

The correct form will be-

Most of the factual information "is" wrong. Some of it at the most elementary level.

Information as a mass noun:

• The noun information has no plural form as it is a mass noun.
• This means that information is a singular noun, hence it will be always followed by 'singular verb forms.'
• However, when it is used for a single fact or detail it can be written as a bit of information or piece of information.

In the above text , information is followed by 'are- a plural verb form' hence we correct that error and change the verb to 'is'.
