Answer with Explanation:
Echo depends on<em> "how sound waves are reflected back."</em> A hard object, like the walls of the multipurpose hall, <em>reflects sound waves well; </em>thus, Seema could easily hear her echo. In addition to this, the walls of the hall are also smooth and this further allows the sound waves to bounce. On the other hand, soft objects like bed cushions in Seema's room<em> absorbs sound.</em> This prevents the sound waves from being reflected. In addition to this, the sound waves have hard time bouncing because there are many objects in Seema's room.
