We use occupied for a room (like a toilet), and engaged for a telephone. They both mean busy.

correct sentence:
I'm afraid the number you want is engaged at the moment so I suggest you ring back later.

Correct entry: engaged
The error was: (b) occupied

You have found the error but your entry is incorrect.
your sentence:
I'm afraid the number you want is busy at the moment so I suggest you ring back later.

If 'engaged' means 'busy' why is the answer incorrect?

[Torsten]

You are right, busy can be used instead of engaged here and we'll add this option as another correct answer.

Hi, all my kind teachers:
I really like these kinds of grammar exercises as they help me revise things i've learned during my self-study.
All i want to say is to thank you (the person who write the test) and your co-workers at www.english-test.net for your committed work.
I've been looking for more exercises to practise. Thanks so much.

1) The Number of Occupied Hotel Rooms: A Time Series Model that
Accounts for Constrained Capacity and Prices
2) While watching BBC Horizon : To Infinity and Beyond a question is mentioned:
In a hotel with infinite rooms all of which are occupied. Can you accomodate a newly arriving guest?
3) Labor Day may see record for occupied hotel rooms
-So, what's wrong with 'occupied room/number'?
Thanks.

[Mister Micawber]

Nothing, but the question is talking about telephone numbers, not room numbers.

Oh, it somehow didn't happen to come to my mind. I wonder if I was the only one who hadn't felt the question.
Thank you, Mr. M.
