Read the following paragraphs from "Behind the Veil." The street, although wide, was inconveniently full of strollers passing to and fro. The situation was not helped by the sleek swift cars, which sped by from time to time. They carried wealthy occupants, young women and ladies, who, protected from the curiosity of the outside world, displayed radiant faces. Their shining gaze roved across the street, smiling or frowning as they took in the sights which pleased or displeased them. Among the surging crowd was an amazing mixture of different clothes and contrasting shapes, which if nothing else, serve to emphasize the varying tastes of these passers-by. A European who had never been to the East before might be excused for thinking that its people were in the middle of a great festival.
