The musical is definitely the genre of the day. (1).

There are 42 musicals currently running in New York, 31 in London, 10 in Paris, and six in Berlin. In six months, Moscow will catch up with Paris, as several premiers are being readied for launch, even prior to the opening of the next theatre season.

The musical is not like an ordinary theatrical production. In this musical, actresses fly over the stage, while the stage itself transforms into an icebreaker. (2). The musical presents a lot of unfamiliar music, creating an atmosphere the audience can really enjoy.

It goes without saying that this musical has also become a symbol in Moscow of the recent hostage tragedy. The bandits who took the audience hostage in the Dubrovka Theatre Centre on Melnikova Street knew exactly where to find a group of contemporary middle-class Muscovites. (3). The result is well-known to everyone around the globe: three nightmarish days and nights.

A completely new attitude has developed towards musicals after those unforgettable days in October. Even as the tragedy was unfolding, voices were being raised demanding Nord-Ost never again be shown to the public, and that collaterally, all other musicals should be shut down as well. (4). The terrorists failed in one respect: they could not sow the seeds of sadness and despondency in our hearts, or to turn spectators off to the most positive and optimistic of theatrical styles.

Task
Four sentences have been removed from the text. Choose from the sentences the one which fits each gap (1-4). There is one extra sentence which you do not need to use.

But cooler heads, as well as the general optimism and cheerfulness of Muscovites have prevailed, and Nord-Ost will continue its triumphant run in the Russian capital.

Even the choice of Nord-Ost was probably not random: it is definitely the most patriotic and domestic musical.

Musicals are doing good business once again, and the communication between artists and audiences is at an unprecedented level.

Actors sing, dance and even turn cartwheels, while sets change every five minutes.

Even though musicals have been showing in Moscow for a number of years, there has never been as great boom as there is this season.
