From the words or group of words lettered A to D, choose the word or group of words that best completes each of the following sentences.
………………..a new teacher, she does not know much about the behaviour of the students.
The correct answer is: A
Explanation
The sentence would read: "Having been a new teacher, she does not know much about the behaviour of the students."
This option correctly uses the perfect participle to indicate that she was a new teacher in the past, which is the reason she doesn't know much about the students' behaviour.
