Irene introduces us to Venice, unique city, rare and famous throughout the world. Not only for its architectural beauty and historic monuments, but also for its art and cultural exhibitions. Venice is definitive a must-see city.

In this video, Irene talks about the Rialto Bridge, the most famous and important of the bridges that cross the Grand Canal in Venice.

Irene tells us about one of the most famous squares in the world: St. Mark's Square in Venice, with its splendid and architecturally important buildings.

If you have ever wondered how to make the traditional Easter bread called la Colomba (the dove), in the shape of a dove, the head of a Turin pastry shop invites us into his laboratory-kitchen where Federica gives us detailed instructions as she demonstrates the first phase. Key is il lievito madre (sourdough starter).

Federica continues working on the dough, adding various ingredients, and making sure that the dough "meshes" without breaking apart. Finally she will shape the dough into the form of a dove.

Federica demonstrates the final stages of making the Colomba. Once ready, she cuts it open to show us what it looks like on the inside, with its particular consistency.

Serena tells us a little bit about Yabla and some of its special features, notably, the option for slow and loop listening, and captions that can be visible or hidden.

Arianna just got her Marketing degree and is looking for a job. Let's see how she goes about it.

Arianna goes to her job interview. How did she do? Should she have answered any questions differently? Are there some important questions she neglected to ask? Do you think she will get the job?

Arianna is on tenterhooks waiting for the phone call that could change the course of her life. When she can't bear it any longer, the phone rings. No caller ID.

Arianna starts work at Phones and More. Her first task is to call a list of publications to find out about ad space. When she gives her email address, she uses the word chiocciola [snail] for the @ sign. Koreans also say "snail shell" when they see an @ sign, while the Dutch see a monkey's tail, and the Norwegians see a pig's tail.

Arianna has been made the head of a new marketing team. Too bad the woman reporting to her let things go sideways.

Marika's goof-up and an increase in printing costs make Arianna's job all the harder. Fortunately, she and Adriano may be able to work something out.
