Answer :
In the book "The Diary of a Young Girl" by Anne Frank, most of the annex residents are worried that the burglar may have seen some of the them and may choose at any moment to report their presence to the authorities.
This is a great threat to the residents of the annex as they are very cautious to be discovered and take great pains to ensure that their secret remains a secret.
In the office, all the chairs are arranged in a circle around the radio which is tuned into an English broadcast. This scares the annex residents because if the police were to be alerted about their presence their secret would be disclosed and the annex residents and their helpers would have to face serious repercussions.
