Identify the segment that contains a grammatical error. If there is no error, select 'No error'.

'He wants something done, / and it has not happen / fast enough,' he said.

The correct answer is option (4).Key Points

• The erroneous segment is “and it has not happen”.
• This segment is in the present perfect tense. Rule (Subject + have/has +V3)
• ‘happen’ is the base form(V1) of verb. The past participle(V3) form of the verb is ‘happened’.
• Hence, it should be written as “and it has not happened”.
  • For example: He has completed his task.

Therefore, the correct sentence is “He wants something done, and it has not happened fast enough,” he said.

Additional Information 

• The phrase "something done" is a way of expressing that a task or action needs to be completed without specifying the exact task.
• It's a general term used when someone wants a particular action to be taken care of, but they may not provide all the details about what that action is.

Confusion Points

• It is a direct speech.  
• It is not necessary to change the tense which is under quotation.
• If we change it into indirect, we have to change it into past tense.
• In this context, no need to change it.
