Ex Input:
passage: A peer-to-peer network is designed around the notion of equal peer nodes simultaneously functioning as both ``clients'' and ``servers'' to the other nodes on the network. This model of network arrangement differs from the client--server model where communication is usually to and from a central server. A typical example of a file transfer that uses the client-server model is the File Transfer Protocol (FTP) service in which the client and server programs are distinct: the clients initiate the transfer, and the servers satisfy these requests.
 question: in peer to peer network each computer runs both client and server software?

Ex Output:
Yes


Ex Input:
passage: Cascading Style Sheets (CSS) is a style sheet language used for describing the presentation of a document written in a markup language. Although most often used to set the visual style of web pages and user interfaces written in HTML and XHTML, the language can be applied to any XML document, including plain XML, SVG and XUL, and is applicable to rendering in speech, or on other media. Along with HTML and JavaScript, CSS is a cornerstone technology used by most websites to create visually engaging webpages, user interfaces for web applications, and user interfaces for many mobile applications.
 question: the primary purpose of css is to format the display of a web page?

Ex Output:

Yes
