Identify the grammatical error in the sentence below.
Qatar has extended strict quarantine rules having required travellers to isolate for up to 14 days upon their arrival in the country.
Show answer & explanation
Correct answer: C
Explanation
Correct Answer: having required travellers
Explanation
The error lies in the use of the perfect participle phrase 'having required'.
A perfect participle (having + V3) represents an action completed prior to another action. In this context, the quarantine rules actively and continuously mandate the condition.
To correctly modify 'quarantine rules', the present participle 'requiring' (or relative clause 'which require') must be used.
Correct Sentence: Qatar has extended strict quarantine rules requiring travellers to isolate for up to 14 days upon their arrival in the country.
