              Amit and Vivan were waiting to go across a railway crossing. Amit jumped over the barrier and curiously put his ear on the railway track. Vivan opposed Amit and pulled him away from the railway track. Read the above passage and answer the following questions (a) Why did Amit put his ear on the railway track? (b) Sound travels faster through copper or water? (c) Why did Vivan pulled Amit away from the railway track? What value of Vivan does this show?  

Answer:

                            (a) Amit put his ear on the railway track to hear the sound of the coming train. Sound travels within railway track and gives the idea of distance of incoming train.                              (b) Copper, because sound travels faster in solid.   (c) Vivan pulled Amit away from the railway track for the safety of his friend. This shows the caring and concern value of Vivan.
