Question

which part is error

It is interesting to note/ that none of these orders/ has been signed by the minister/ no error​

Answer 1

Answer:

have been instead of "has been", because has is used for singular here plural is referred so we should use have.

Answer 2

No error -This is the answer.

Rectifying error:

• In the question given, we must find out the error in it and also correct it.
• When we are given a sentence to spot the mistake, we must check if there is agreement among the parts of speech in it.
• Especially, the agreement between subject and verb must be looked into.
• Here the subject is 'non of these orders'. Though 'these orders' is plural, 'none' means no and so it is considered to be singular.
• The verb 'has been' is also in singular and thus it is right here.
• The preposition 'to' and 'by' are also correctly used.
• There is no other mistake in the sentence that must be corrected.
• Therefore the answer is: no error.
