A QUE S ! is a provocative post-intermediate Spanish conversation book designed to increase students' awareness of Hispanic culture. The text encourages critical thinking while challenging the students' ability to express themselves in Spanish by providing them with an opportunity for in-depth exploration of relevant contemporary issues. The Fourth Edition presents four main themes around which all the text and supplemental materials revolve: Espacios: Publicos y privados, Encuentros y desencuentros, Patria/Nacion: Acercamientos, and De ac para all . Each thematic unit is supported by creative activities and engaging authentic materials. Both Spain and Latin American countries are represented, as are male and female writers, and a few of the different ethnic groups that comprise Hispanic culture.
